CNC Rotary Table Pre-Shipment Checklist: Inspection, Packing and Shipping Details

Before ordering a CNC rotary or tilting table, agree what will be checked, what evidence will be supplied and who is responsible for packing, transport and installation. A clear written scope helps both buyer and sourcing service coordinate the shipment.

ROTIVEX provides sourcing support from Shanghai, including technical confirmation, inspection and packing/shipping coordination with the scope agreed in the quotation. The checklist below is a planning tool. It is not a statement that every listed test, document or service is included in every order.

What should a CNC rotary table quotation include?

A useful quotation identifies the exact model and configuration, lists included and excluded components, and states the agreed inspection, packing, shipment and service responsibilities. Compare the complete scope before comparing the headline price. A catalogue model name alone does not establish what will be supplied or whether it will integrate with your machine.

Question to ask	What the quotation should make clear
Which configuration is quoted?	Complete model and suffix, quantity, drawing revision and accepted specification.
What hardware is included?	Table, motor, drive, encoder, cables, connectors and controller or interface items, each identified as included, excluded or requiring confirmation.
What must the buyer provide?	Clamping supply, machine-side interfaces, fixtures and any other application-specific items.
Who confirms integration?	Responsibility for reviewing the actual machine/controller and for installation, wiring and commissioning.
How will the order be checked?	Agreed evidence, test conditions where applicable, acceptance criteria and any inspection charges.
What happens after dispatch?	Shipment scope, receiving arrangements and the written warranty and service-cost responsibilities applicable to that order.

Not sure about every technical detail yet? Start with your machine and controller model, intended machining mode, workpiece plus fixture details, quantity and destination. Mark unknown items for review. Use the compatibility checklist to prepare questions, or browse the ROTIVEX catalogue for reference models. Final configuration and commercial terms require written confirmation.

1. Confirm the ordered configuration

Exact model and suffix: for example, MRNC-255 versus MRNC-255N.
Accepted specification and installation drawing, including revision.
Motor, encoder, cables, connectors, controller or interface scope, including excluded items.
Clamping supply, accessories, fixtures and tailstock where applicable.
Quantity, consignee, destination and agreed shipment terms.

Keep the accepted quotation and configuration record together. A catalogue page is a reference; it does not replace the final agreed order specification.

2. Agree the inspection evidence before payment

Specify the checks and evidence needed before dispatch. Ask for confirmation of their availability, cost and timing before treating them as part of the order.

Model identification and, where available, serial-number records.
Overall-condition photos and close-ups of mounting faces, table surface and connection points.
Confirmation of agreed accessories and separately packed components.
Checks of agreed mounting dimensions or interfaces where included.
Movement and clamping demonstration where the necessary test setup is available.
Accuracy or repeatability records if specifically required and agreed.

A photo or movement video does not verify positioning accuracy, loaded cutting performance or compatibility with the buyer’s machine. Where a measured test is required, agree the method, conditions, acceptance limits and report before ordering.

Also record how discrepancies will be handled: who reviews the evidence, which issues must be resolved before release and whether a revised shipment date is needed.

3. Review surface protection and packing

The MRNC-255/320 units shown in the supplied reference photos have an anti-rust oil coating. Confirm the protection method for the actual shipment and request the relevant cleaning and handling instructions before installation.

Protection of exposed metal, connection points and vulnerable components.
Restraint and support suitable for the actual unit and shipment.
Separate identification and protection of loose accessories.
Package quantity, gross weight and external dimensions.
Handling information and package markings required for the chosen shipment.
Final packing photos, if agreed.

If a wooden package is proposed, ask the logistics provider to confirm the destination’s applicable packaging and documentation requirements. Do not assume that a particular crate type or treatment is included without written confirmation.

4. Separate dispatch timing from delivery timing

ROTIVEX’s stated dispatch timing is within 10 working days after receipt of the agreed payment and confirmation of the technical configuration. Dispatch means shipment from origin. International transit, customs clearance and delivery to the buyer’s site are additional.

Before accepting the quotation, confirm the delivery destination, shipping method, shipment terms, freight charge, insurance scope if requested, customs responsibilities and unloading arrangements. Ask for any required inspection or documentation to be included in the agreed schedule.

Do not arrange installation around an assumed arrival date. Use the confirmed shipment information and current logistics estimate.

5. Prepare the receiving and installation handover

Confirm who receives the shipment and checks package condition and item count.
Record visible discrepancies promptly and retain the relevant packaging and photos for review.
Confirm safe handling arrangements and the supplier’s installation instructions.
Keep the accepted drawings, packing list and available operating documents accessible to the installation team.
Confirm machine integration, labor and commissioning responsibilities before work starts.

Receiving checks do not replace technical acceptance or the installation procedure. If a problem is found, contact the seller with identification details and evidence before arranging repairs or returns.

Warranty and service-cost scope

One-year limited warranty runs from the dispatch date for confirmed manufacturing or material defects under normal use. The seller covers approved replacement parts and standard outbound freight for those parts. The buyer covers removal and installation labor, duties and taxes, and any expedited freight surcharge. On-site service or factory-return costs must be agreed in writing before work begins. Remote diagnosis is available without a service charge.

Read the procurement service and warranty overview. The contracting seller and final order terms are confirmed before purchase; request clarification of any cost or responsibility not stated in the quotation.

Send your requirements in one message

Provide the model and quantity, machine/application details, destination, required timing, inspection evidence required, packing requirements and any documents requested by your receiving team. Mark unknown items for review.

Use the technical inquiry worksheet for machine and workpiece details, and include your inspection and logistics requirements with the saved PDF and drawings.

Vera provides an initial reply within 12 hours. Technical confirmation, inspection scope, quotation and shipment arrangements follow review.

TRNC-255A vs TRNC-255B vs TRNC-321: Comparing Tilting Rotary Tables

TRNC-255A and TRNC-255B both have a 255 mm worktable, but their catalogue dimensions, load limits, tilt ranges and weights differ. TRNC-321 has a 320 mm worktable. Compare the complete installation and machining requirement before choosing by diameter.

Key catalogue differences

Selection item	TRNC-255A	TRNC-255B	TRNC-321
Worktable diameter	255 mm	255 mm	320 mm
Through-hole diameter	Not listed (—)	100 mm	100 mm
Table height, horizontal position	400 mm	330 mm	350 mm
Center height at 90°	400 mm	235 mm	255 mm
Tilting range	−30° to +120°	−40° to +120°	±110°
Allowable load at 0°, horizontal	100 kg	140 kg	200 kg
Catalogue tilting load	75 kg	80 kg	100 kg
Net weight, motor excluded	650 kg	300 kg	450 kg

Source: the supplied TANSHING catalogue, printed pages 47–50 (PDF pages 25–26 in the supplied scan). Values are references for the catalogue configuration and require confirmation against the accepted order drawing. The tilting-load row is labelled 0°–90° and 0° to −90° on the TRNC-255A/255B sheet, and 0°–90° on the TRNC-321 sheet. Read these labels together with each model’s mechanical tilt range; they do not establish load capacity across the full travel. Confirm the required angle and load geometry. A dash is not a confirmed zero or proof of an available passage.

Same diameter does not mean the same installation

The two 255 mm models have different listed heights and unit weights. Include the rotary unit, motors, fixtures, workpiece and other equipment in the machine-table payload check. Separately check the rotary table’s workpiece-and-fixture load limits.

Review the exact drawings for the base, mounting interface, motor and cable envelope, tool access and the swept envelope at each required tilt angle. A lower table height or lower unit weight alone does not establish clearance or suitability.

Use the model comparison and dimensional references on our CNC 5-axis tilting rotary table page.

Match the load to the machining position

Add the workpiece, chuck, fixture and attached components. Use the load row corresponding to the operating position. Also confirm load offset, inertia, allowable moments, cutting forces and clamping conditions.

For an illustrative combined load of 90 kg, the catalogue horizontal-load values alone would leave all three models as candidates. In the catalogue tilting-load row, 90 kg exceeds the TRNC-255A and TRNC-255B values and is below the TRNC-321 value. This is a screening example, not application approval; the actual angle and load geometry still require review.

Verify the required tilt direction and through passage

State the actual angles needed and check the drawing’s sign convention. TRNC-321’s ±110° range is different from the −30°/+120° and −40°/+120° ranges of the 255 models. Confirm the part, fixture, spindle and machine enclosure remain clear throughout the intended movement.

If a through passage is required, describe its intended use and required clear diameter. TRNC-255B and TRNC-321 list a 100 mm through hole, but an installed fixture or another component may restrict the usable passage. TRNC-255A has a dash in this catalogue row; request confirmation rather than assuming a usable bore.

Separate 3+2 positioning from simultaneous machining

Two rotary axes do not by themselves establish simultaneous five-axis capability on the machine. Confirm the CNC control, enabled functions, drives, motors, encoders, interfaces and integration scope for the required operation.

For the broader decision between indexed positioning and simultaneous machining, read how to choose a CNC 5-axis rotary table. Confirm rotary-axis and tilt-axis specifications separately before ordering; the table above is not a complete performance specification.

Request a comparison for your machine and part

Machine model, CNC controller and required machining mode.
Required rotary and tilt angles, with the installation drawing.
Part and fixture drawings, combined mass and load offset.
Available mounting space, machine payload and travel limits.
Required passage, clamping supply, quantity and destination.

MRNC-255 vs MRNC-320: Which CNC Rotary Table Fits Your Setup?

Compare MRNC-255 / 255N and MRNC-320 / 320N by installation orientation, combined workpiece and fixture load, mounting space and control requirements. A larger table diameter alone does not establish suitability.

MRNC-255 is a candidate where a 255 mm faceplate and its catalogue load limits suit the application. MRNC-320 provides a 320 mm faceplate and higher listed load limits, but also adds table mass and installation space requirements. Both require application and configuration confirmation before ordering.

Catalogue comparison

Selection item	MRNC-255 / 255N	MRNC-320 / 320N
Worktable diameter	255 mm	320 mm
Through-hole diameter	33 mm	40 mm
Table height, horizontal installation	167 mm	222 mm
Center height, vertical installation	160 mm	210 mm
Allowable load, vertical installation	100 kg	150 kg
Allowable load, horizontal installation	250 kg	350 kg
Allowable load, with tailstock	250 kg	350 kg
Indexing accuracy / repeatability	15 / 4 arcseconds	15 / 4 arcseconds
Maximum table speed	16.6 rpm	16.6 rpm
Net weight, motor excluded	93 kg	174 kg

Source: the supplied TANSHING catalogue, printed pages 13–14 (PDF page 8 in the supplied scan). These are catalogue reference values, subject to the accepted order configuration and drawing. Maximum speed is not a guaranteed loaded machining speed. Positioning figures are not finished-part tolerances.

Start with the combined load and its orientation

Add the workpiece, chuck, fixture and attached components. Compare that total with the rating for the actual installation orientation. Do not apply the horizontal rating to a vertical setup.

For example, an illustrative 120 kg combined load exceeds the MRNC-255 vertical catalogue limit of 100 kg and is below the MRNC-320 vertical limit of 150 kg. This makes MRNC-320 a candidate for further review; it does not approve the application. Load offset, inertia, allowable moments, cutting forces and clamping still need checking.

A tailstock arrangement also requires alignment, support and mounting confirmation. A listed tailstock load figure does not mean a tailstock is included in the quotation.

Two workpieces clamped on a bridge fixture between rotary and support units. — Multi-station bridge-fixture application reference. Include all workpieces, fixtures, clamps and adapters in the load review, together with their orientation and offset from the rotary axis. Suitability requires configuration-specific technical confirmation.

Check the machine envelope before choosing the larger model

MRNC-320 adds 81 kg of catalogue net weight before the motor. Check the machine-table payload including the rotary unit, motor, fixtures, workpiece and other installed equipment. Machine payload and rotary-table allowable load are separate checks.

The different table and center heights affect tool access, tailstock matching and travel clearance. Review the exact dimensional drawing, mounting interface, cable and motor clearance, and the swept envelope of the rotating part and fixture.

See the drawings on the MRNC-255 / 255N product page and MRNC-320 / 320N product page.

Rotary unit and tailstock installed on a machining-centre table. — Rotary unit and tailstock installation reference. Check the combined installation length, centre height, spindle clearance and tool access for the proposed setup. The photograph does not establish a specific MRNC model or machine compatibility.

Standard or N: confirm the motor-cover dimensions

The catalogue groups standard and N versions in shared specification columns. N identifies the shortened motor-cover configuration. Select the exact suffix from its drawing and confirmed motor installation; do not treat N as an accuracy or load-capacity upgrade.

Confirm the control and clamping configuration

Specify whether the job needs indexed positioning or simultaneous fourth-axis machining. Controller brand alone does not establish compatibility: confirm the control model, enabled axis functions, drive, motor, encoder, interfaces and installation scope. Check hydraulic clamping requirements and the agreed supply scope as well.

Use the fourth-axis compatibility checklist to collect the machine details. For terminology and parameter interpretation, see the rotary table specifications guide.

4th-Axis Rotary Table Compatibility Checklist

Before buying a fourth-axis rotary table for an existing machining center, check both machine integration and the complete workholding setup. A suitable table diameter is only one part of the decision. The controller, drive, servo feedback, installation space and clamping system must also match the proposed configuration.

Use this checklist to prepare a technical review with your machine supplier or integrator. If your main question is which table size to choose, start with our 4-axis rotary table selection guide.

1. Define the Machining Mode First

Indexed positioning: the rotary moves to an angle, then the part is machined with the axis held as required by the setup. Simultaneous fourth-axis machining: the rotary axis moves in coordination with the machine axes during cutting.

A separate indexing controller triggered by an M-code does not, by itself, provide coordinated fourth-axis interpolation. Confirm the required machining mode before comparing the controls or requesting a quote. Include a drawing or a short description of the operation.

2. Confirm the Exact CNC and Servo Configuration

Information to collect	What needs confirmation
Machine make, model and build year	The exact machine configuration and available axis provisions.
Controller model and software version	Fourth-axis functions, enabled options and supported operating mode.
Installed drive/amplifier and spare axis provision	Whether the required hardware is present or an upgrade is needed.
Servo motor and encoder identification	Motor, drive and feedback compatibility for the proposed configuration.
Connector and cable information	Verified electrical interfaces and cable requirements; connector appearance alone is insufficient.
Clamp/unclamp signals and status feedback	The control sequence, interlocks and confirmation signals required by the machine.

“FANUC,” “Siemens” or another controller brand is not enough to establish compatibility. Send the exact model and configuration for review. Electrical changes, parameter settings and commissioning should be handled by the machine supplier or a qualified integrator.

3. Check the Entire Installation Envelope

Compare the drawing of the exact rotary version against the machine table, T-slots, travel limits and spindle clearance. Include the motor cover, connectors, cable bend space, chuck, fixture and workpiece. Check the swept envelope through all intended rotary positions, as well as tool changes, probing and door access.

For long parts, include the tailstock or support unit in the layout. Its center height and mounting position need to suit the selected rotary setup. The N versions of MRNC products have a different motor-cover arrangement, so use the drawing for the version being quoted.

Bridge fixture between a rotary unit and opposing support inside a machining centre. — Rotary table and opposing support with a bridge fixture inside a machining centre. Review the complete fixture envelope, support arrangement and available machine travel. Application reference; the exact model and compatibility require confirmation.

4. Separate Machine Payload from Rotary Load

The machine table supports the rotary unit, motor, fixture, workpiece and any support equipment. The rotary’s allowable work load is a separate limit. Confirm installation orientation, fixture and part mass, center-of-gravity offset, inertia and cutting moments. A part weighing less than the catalog load rating can still require further review.

For example, the catalog net weights of MRNC-255 / 255N and MRNC-320 / 320N are 93 kg and 174 kg respectively, excluding the motor. Include the other setup components when checking machine capacity. These weights do not establish suitability for a particular machine.

5. Confirm Clamping Supply and Delivery Scope

Check the required hydraulic or pneumatic supply for the exact model: operating pressure, available supply equipment, hoses, fittings, valves and electrical control. Confirm which items are included in the quotation and which are supplied by the buyer or integrator.

Record responsibility for mounting, electrical integration, control setup, alignment and acceptance checks. Agree how positioning, clamp operation, clearance and the intended machining cycle will be checked before production use. For specification definitions, see rotary table specifications explained.

Send These Details for a Compatibility Review

Copy the following into your inquiry. If something is unknown, mark it “to be confirmed” rather than guessing.

Machine make / model / year:
Controller model / software version:
Existing fourth-axis drive or option:
Indexed positioning or simultaneous machining:
Preferred rotary model, if known:
Machine table dimensions / payload limit:
Available mounting space / spindle clearance:
Installation orientation:
Workpiece and fixture dimensions / combined mass:
Workpiece offset / support or tailstock requirement:
Available hydraulic or pneumatic supply:
Quantity / destination country:
Available drawings or identification photos:

Common Questions

Can any three-axis machining center accept a fourth axis?

It requires machine-specific confirmation. Physical space, control options, drive hardware and interfaces must be checked together. A machine may require additional hardware or may not support the intended operating mode.

Can I reuse my existing servo motor?

Do not assume that a matching controller brand or motor mounting pattern is sufficient. Provide the motor identification, drive details and encoder information for technical review.

What if I do not have all the technical details?

Start with the machine and controller identification, application and available drawings. ROTIVEX can help identify the remaining information needed for the proposed setup.

Technical References

Manufacturer guidance illustrates why integration must be checked by configuration. Haas documents axis-drive requirements in its rotary installation guide and distinguishes motor and control versions in its compatibility guide. These references apply to Haas equipment; they do not establish MRNC compatibility with a Haas machine or replace the manuals for the equipment being supplied.

CNC Rotary Table Specifications: What Do Table Diameter, Through Hole and Accuracy Mean?

When selecting a CNC rotary table, buyers often compare a long list of technical specifications.

Table diameter, through hole, load capacity, indexing accuracy, repeatability and maximum speed can all affect whether a rotary table is suitable for a particular machining application.

Understanding these specifications can make it easier to compare different models and select a suitable configuration for your CNC machine.

Read the Specification Together with Its Conditions

Before comparing two models, record the installation orientation, included equipment and measurement conditions for each value. A specification without its conditions may describe a different setup from yours.

Specification	Selection check
Load capacity	Add the workpiece, chuck, fixture and attached components. Confirm the rated orientation, load offset and applicable machining conditions.
Drive torque and clamping torque	Keep these separate: the capacity to move an axis and the capacity to hold it for cutting answer different questions.
Indexing accuracy and repeatability	Check units, test conditions and whether the value applies to the rotary or tilting axis.
Maximum speed	Confirm the permitted load, drive configuration and required duty; the maximum figure alone does not define a machining cycle.
Center bore and through hole	Check the dimension drawing for the usable passage, bore depths and mounting interfaces.

Angular Accuracy Is Not a Finished-Part Tolerance

An arcsecond is an angular unit: 1° = 60 arcminutes = 3,600 arcseconds. It is not a time measurement. Keep angular units separate from millimetres when comparing specifications.

As a geometric illustration, an angular deviation of 20 arcseconds at a radius of 100 mm corresponds to about 0.0097 mm of tangential displacement (radius × angle in radians). This calculation is not a model specification or a prediction of finished-part accuracy. Machine geometry, workholding, cutting conditions and the rest of the setup also affect the result.

For rotary-and-tilting equipment, confirm the rotary and tilting axes separately. The TRNC comparison table helps identify model-specific values to check.

What Specifications Should You Check?

The most important CNC rotary table specifications usually include:

Table diameter
Table height
Center height
Through hole
Load capacity
Indexing accuracy
Repeatability
Maximum speed
Reduction ratio
Clamping or braking capability
Motor and control configuration

Not every specification has the same importance for every application.

The correct selection depends on your CNC machine, workpiece and machining requirements.

1. Table Diameter

Table diameter refers to the diameter of the rotary table’s working surface.

It affects the size of the workpiece and workholding system that can be installed.

When selecting table diameter, consider:

Workpiece dimensions
Chuck diameter
Fixture dimensions
Available machine space
Required machining access

A larger table is not automatically better.

The table should be large enough for the application while remaining compatible with the machining center.

2. Table Height and Center Height

Table height and center height can affect the available machining space.

This is particularly important when the rotary table is installed on a CNC machining center.

You should check:

Distance between the machine table and spindle
Rotary table height
Center height
Chuck height
Workpiece height
Required tool clearance

The complete setup should be checked rather than considering the rotary table by itself.

3. Through Hole

The through hole is the opening through the center of a rotary table.

Depending on the application, a through hole can provide additional flexibility for workholding and workpiece setup.

It can be useful when working with:

Long components
Bar-type workpieces
Special fixtures
Through-mounted workpieces
Custom workholding arrangements

If a through hole is important for your application, confirm its diameter before selecting a model.

4. Load Capacity

Load capacity refers to the amount of load the rotary table is designed to support according to its specifications.

The complete load may include:

Workpiece
Chuck
Fixture
Clamping components
Other accessories

For this reason, do not calculate the required capacity using only the workpiece weight.

For heavy machining applications, also consider the machining forces and the required clamping or braking capability.

Always check the manufacturer’s specifications for the selected model.

5. Indexing Accuracy

Indexing accuracy describes how accurately the rotary table reaches a commanded angular position.

For example, if a machining operation requires the workpiece to move to several defined angular positions, indexing accuracy becomes an important specification.

It can be particularly relevant to:

Precision indexing
Multi-sided machining
Angular drilling
Repeated machining operations
4-axis machining

When comparing models, use the published accuracy specification rather than relying on general terms such as “high precision.”

6. Repeatability

Repeatability describes how consistently the rotary table can return to the same position.

Accuracy and repeatability are related but are not the same thing.

A rotary table may need both:

Accurate positioning
Consistent positioning from one operation to another

Repeatability can be particularly important for production machining where the same positioning sequence is repeated many times.

7. Maximum Speed

Maximum speed indicates the highest specified rotary speed of the table.

The required speed depends on the machining application.

Consider:

Positioning requirements
Continuous rotation
Workpiece size
Workpiece weight
Machining process
CNC control configuration

A higher maximum speed is not necessarily required for every application.

For many indexing applications, positioning accuracy and stability may be more important than maximum speed.

8. Reduction Ratio

The reduction ratio describes the relationship between the motor movement and rotary-table movement.

Different rotary table designs use different reduction ratios.

The reduction ratio can affect characteristics such as:

Rotary speed
Torque transmission
Positioning behaviour
Motor requirements

When comparing products, use the manufacturer’s published reduction ratio and consider it together with maximum speed and torque specifications.

9. Clamping and Braking Capability

Clamping or braking capability helps maintain the rotary table position during machining.

This can be important when cutting forces act on the workpiece.

The required capability depends on:

Workpiece size
Workpiece weight
Cutting forces
Workholding system
Machining application

For demanding applications, confirm the relevant specifications with the supplier before ordering.

10. Motor and Control Configuration

A CNC rotary table may require a suitable servo motor and control configuration.

Before requesting a quotation, provide:

CNC machine model
CNC control system
Required rotary axis
Motor requirements, if known
Installation orientation

This information can help confirm whether the rotary table configuration is suitable for your machining center.

How to Compare CNC Rotary Table Specifications

When comparing two or more models, avoid looking at a single specification in isolation.

For example, a larger table diameter does not necessarily mean the model is more suitable for your application.

Instead, compare the complete specification set:

Specification	Why It Matters
Table diameter	Workpiece and chuck size
Table height	Machine working space
Center height	Workpiece positioning
Through hole	Workholding flexibility
Load capacity	Workpiece and fixture weight
Indexing accuracy	Angular positioning
Repeatability	Consistent positioning
Maximum speed	Rotary movement requirements
Reduction ratio	Speed and torque characteristics
Clamping / braking	Position stability
Motor / control	CNC compatibility

Example of a Rotary Table Selection Process

Suppose a buyer wants to install a rotary table on a CNC machining center.

The buyer should first identify:

Step 1 — Machine

What is the CNC machine model?

Step 2 — Workpiece

What are the workpiece dimensions and weight?

Step 3 — Workholding

Will the application use a chuck, fixture or another workholding system?

Step 4 — Movement

Does the application require indexing, continuous rotary movement or both?

Step 5 — Accuracy

What positioning accuracy and repeatability are required?

Step 6 — Installation

What table size, height and through hole are required?

Step 7 — Control

What CNC control system will operate the rotary axis?

This information provides a practical starting point for model selection.

Why Product Specifications Should Be Checked Carefully

Different manufacturers may use different terminology or specification formats.

For example, product names such as:

CNC rotary table
CNC index table
CNC dividing head
CNC rotary axis

may describe products with overlapping functions.

The actual technical specifications and intended application should therefore be checked before purchasing.

For B2B buyers, it is also useful to request available technical drawings, installation dimensions and control information when necessary.

CNC Rotary Table Specifications Checklist

Before requesting a quotation, prepare:

CNC machine model
CNC control system
Required table diameter
Required table height
Required center height
Required through hole
Workpiece dimensions
Workpiece weight
Chuck or fixture dimensions
Required indexing accuracy
Required repeatability
Required rotary speed
Required clamping or braking capability
Required quantity

The more complete the information, the easier it is to evaluate suitable configurations.

Frequently Asked Questions

What is the most important CNC rotary table specification?

There is no single specification that is most important for every application. Table size, load capacity, accuracy, through hole, speed and control compatibility should be evaluated according to the machining requirements.

What does rotary table through hole mean?

The through hole is the opening through the center of the rotary table. Its size can affect workpiece and workholding options.

What is the difference between indexing accuracy and repeatability?

Indexing accuracy describes how accurately the table reaches a commanded position. Repeatability describes how consistently it can return to that position.

How do I choose the correct table diameter?

Consider the workpiece dimensions, chuck or fixture size, available machine space and required machining access.

Should I consider load capacity together with the workpiece weight?

Yes. The total setup may include the workpiece, chuck, fixture and other components. Machining forces and clamping requirements should also be considered.

Do CNC rotary table specifications vary between manufacturers?

Yes. Terminology, measurement methods and available configurations can vary. Always compare the actual specifications of the individual model.

How to Choose a CNC 5-Axis Rotary Table

A CNC 5-axis rotary table adds rotary and tilting axes for positioning a workpiece. Before choosing a model, confirm whether your application needs 3+2 positioning or simultaneous 5-axis machining; the table alone does not establish your machine’s simultaneous machining capability.

Start with four checks: the intended machining mode, machine and controller integration, the combined workpiece and fixture load, and clearance throughout the required movement. Use the guide below to prepare your requirements before comparing model configurations.

What Is a CNC 5-Axis Rotary Table?

A CNC 5-axis rotary table is a rotary positioning system that combines rotary and tilting movement.

Depending on the configuration, it can be used for:

5-axis machining
Multi-sided machining
Complex workpieces
Angled machining
Precision positioning
Reduced workpiece setups

The actual movement range and technical capabilities depend on the individual model.

Why Use a 5-Axis Rotary Table?

A conventional rotary table primarily provides rotary positioning.

A CNC tilting rotary table adds another controlled movement, allowing the workpiece to be positioned at different angles.

This can provide several practical benefits.

Access to More Workpiece Surfaces

Tilting the workpiece can provide access to surfaces that are difficult to machine from a fixed position.

Fewer Setups

A suitable 5-axis configuration can reduce the need to manually reposition the workpiece between operations.

More Flexible Machining

Rotary and tilting movements can provide greater flexibility for complex machining operations.

Improved Workpiece Accessibility

Different tool approaches can be achieved by changing the orientation of the workpiece.

1. Check Your CNC Machine

The first step is to confirm your CNC machine configuration.

Provide information such as:

CNC machine model
Vertical or horizontal machining center
Machine table dimensions
Available installation space
CNC control system
Available axis configuration
Installation orientation

A 5-axis rotary table must physically fit the machine and be compatible with its control system. First specify whether your process needs 3+2 positioning or simultaneous 5-axis machining.

3+2 Positioning or Simultaneous 5-Axis Machining?

3+2 positioning: the rotary and tilting axes orient the workpiece before a 3-axis cutting operation. This can suit drilling, milling and machining several faces at fixed angles.

Simultaneous 5-axis machining: linear and rotary axes move together during cutting. It requires a compatible machine, control, rotary table and CAM/postprocessor configuration.

A table with two rotary axes does not by itself make an existing machining center capable of simultaneous 5-axis cutting. Confirm the intended operating mode with the machine builder or integrator before selecting a model.

2. Consider the Workpiece Dimensions

Workpiece size is one of the most important factors when choosing a 5-axis rotary table.

Consider:

Length
Width
Height
Weight
Required machining access
Workholding requirements

Check the swept envelope of the complete workpiece, chuck and fixture through every required rotary and tilt position. Include clearance to the spindle, toolholder, machine enclosure and nearby fixtures, as well as usable Z-axis travel.

Request the installation drawing and check mounting dimensions, center height and cable or hose routing. Table diameter alone does not establish whether the assembled setup will fit or whether the tool can reach every required surface.

3. Consider Workpiece Weight

The total load may include:

Workpiece
Chuck
Fixture
Clamping components
Other accessories

Check the published load rating for the actual table orientation and tilt angle. A horizontal load rating should not be assumed to apply when the table is tilted. Include the mass of the fixture and chuck when checking the permitted load.

The required capacity should be evaluated together with the actual machining forces, load offset and workholding configuration. Use the TRNC model comparison to shortlist models by table diameter, through-hole, tilt range and orientation-specific load capacity, then confirm the complete setup with the supplier.

4. Check Rotary and Tilting Range

One of the main differences between 5-axis rotary tables and conventional rotary tables is the additional tilting movement.

When comparing models, check:

Rotary range
Tilting range
Tilting direction
Mechanical clearance
Required machining angles

The required range depends on the workpiece geometry and machining process.

A larger movement range is not automatically necessary for every application.

5. Check Indexing Accuracy and Repeatability

Accuracy is important when the rotary table is used for precision machining.

Review:

Rotary positioning accuracy
Tilting positioning accuracy
Repeatability
Required machining tolerance

For production applications, repeatability can be particularly important because the rotary and tilting axes may be used repeatedly.

Check accuracy and repeatability separately for the rotary and tilting axes. Compare the manufacturer’s published specifications with your part tolerances; a table positioning specification alone does not guarantee the finished part tolerance. Our CNC rotary table specifications guide explains the main terms to review.

6. Check Maximum Speed

Maximum rotary and tilting speed should match the machining process.

Consider:

Positioning speed
Continuous rotary requirements
Workpiece weight
Workpiece dimensions
Machining process

For many applications, positioning accuracy and stability may be more important than maximum speed.

7. Check Clamping and Braking

A 5-axis rotary table must maintain stable positioning during machining.

The required clamping or braking capability depends on:

Workpiece weight
Workpiece dimensions
Cutting forces
Workholding system
Machining application

For demanding applications, confirm the relevant technical specifications before purchase.

8. Check CNC Control Compatibility

Control compatibility is especially important for a 5-axis configuration.

Before requesting a quotation, provide:

CNC machine model
CNC control system
Required rotary axis
Required tilting axis
Servo requirements
Installation orientation

Provide the exact controller model and version, available axis options, and servo motor, drive and encoder details. Ask the machine builder or integrator to confirm axis integration and clamp/unclamp signals. Matching the controller brand alone is insufficient.

For simultaneous machining, also confirm the supported machine kinematics, any required control options, tool-center-point functions where applicable, and a suitable CAM postprocessor. Request written confirmation of the intended machining mode for your machine and rotary table combination.

9. Consider the Workholding System

The rotary table and workholding system should be considered together.

Possible workholding options may include:

CNC chuck
Pneumatic chuck
Hydraulic chuck
Manual chuck
Custom fixture
Special workholding system

The selected chuck or fixture must provide sufficient clearance for the rotary and tilting movements.

5-Axis Machining Applications

CNC 5-axis rotary tables can be used in applications where flexible workpiece positioning is required.

Complex Workpieces

Components with multiple angled surfaces can benefit from rotary and tilting positioning.

Multi-Sided Machining

A 5-axis rotary table can help access several surfaces without repeatedly removing the workpiece.

Angled Machining

Tilting allows the workpiece to be positioned at different angles for machining operations.

Precision Components

Controlled rotary and tilting positioning can support applications requiring repeatable positioning.

Reduced Setup Operations

A suitable configuration can reduce manual repositioning between machining operations.

CNC 5-Axis Rotary Table vs Conventional Rotary Table

A conventional CNC rotary table primarily provides rotary positioning.

A 5-axis rotary table adds a tilting movement, which can provide additional flexibility for complex machining.

The choice depends on the application.

A conventional rotary table may be suitable when the main requirement is rotary positioning and multi-sided machining.

A 5-axis configuration may be considered when the machining process requires different workpiece orientations or angled access.

The actual product specifications should always be checked before selecting a configuration.

CNC Rotary Table vs CNC Index Table: What Is the Difference?

CNC rotary tables and CNC index tables are both used for controlled workpiece positioning, but their functions and applications can be different.

Understanding the difference between a CNC rotary table and a CNC index table can help you select a suitable solution for your machining center.

The right choice depends on the machining process, positioning requirements, workpiece characteristics and CNC machine configuration.

Start with the Required Machining Motion

First ask whether the rotary axis must move while the tool is cutting. Product names alone do not establish this capability: confirm the individual table, drive and machine-control configuration.

Your process	What to confirm
Rotate, stop and machine each face	Check every required angle, positioning performance and clamping sequence.
Rotate while cutting	Confirm coordinated rotary-axis motion with the machine supplier, including drive, controller and programming support.
Add both rotation and tilt	Review a tilting setup and confirm whether the application needs 3+2 positioning or simultaneous motion.

A table with fixed indexing increments must support the angles in your program. For example, a 5° increment does not provide a 7° index position. Check the selected model rather than assuming that all index tables offer the same increments.

For rotary-and-tilting applications, use the 5-axis selection guide. For technical terminology, read the rotary table specifications guide.

What Is a CNC Rotary Table?

A CNC rotary table is a rotary positioning device that allows a workpiece to be rotated around a controlled axis.

Depending on the configuration, it can be used for:

4-axis machining
Multi-sided machining
Angular positioning
Continuous rotary movement
Precision positioning
Complex machining applications

A rotary table can provide controlled rotary movement in addition to the linear axes of a CNC machining center.

What Is a CNC Index Table?

A CNC index table is designed primarily for controlled angular indexing and positioning.

Instead of manually rotating the workpiece between operations, the CNC index table can position the workpiece at defined angles.

Typical applications include:

Multi-sided machining
Drilling on multiple faces
Milling at defined angles
Repeated indexing operations
Precision positioning
Production machining

The exact functions depend on the specific model and configuration.

CNC Rotary Table vs CNC Index Table

The terms can sometimes overlap because both products provide rotary positioning.

However, the practical difference is often related to how the rotary axis is used.

Feature	CNC Rotary Table	CNC Index Table
Main purpose	Rotary positioning and movement	Controlled angular indexing
Multi-sided machining	Yes	Yes
Angular positioning	Yes	Yes
Continuous rotation	Depending on configuration	Depending on configuration
4-axis machining	Common application	Possible depending on configuration
Precision indexing	Yes	Yes
Workholding integration	Chuck or fixture	Chuck or fixture
CNC integration	Depends on configuration	Depends on configuration

Always check the specifications of the individual model before selecting a product.

When Should You Use a CNC Rotary Table?

A CNC rotary table may be suitable when your machining process requires controlled rotary movement or flexible positioning.

For example, it can be considered for:

4-Axis Machining

A rotary table can provide an additional controlled rotary axis for a machining center.

This can allow the machine to access different surfaces or orientations of a workpiece without repeatedly removing and repositioning it.

Multi-Sided Machining

A rotary table can help position several sides of a workpiece for machining.

This can reduce manual repositioning and help maintain a consistent workholding setup.

Angular Machining

When machining features at different angles, controlled rotary positioning can provide a more flexible setup.

The required accuracy and positioning method depend on the application.

When Should You Use a CNC Index Table?

A CNC index table can be useful when the primary requirement is repeatable angular positioning.

For example:

Drilling multiple hole patterns
Machining several faces
Repeated production operations
Positioning components at defined angles
Multi-sided machining

For these applications, indexing capability and repeatability are important specifications to review.

What Is a CNC Dividing Head?

The term CNC dividing head is also commonly used when discussing rotary positioning equipment.

A dividing head traditionally refers to equipment used to divide or position a workpiece at specific angular intervals.

Modern CNC dividing heads and CNC rotary tables can provide more advanced controlled positioning and CNC integration.

Because terminology varies between manufacturers and markets, buyers should focus on the actual specifications and intended application rather than the product name alone.

Key Specifications to Compare

Whether you are considering a CNC rotary table or CNC index table, several specifications should be reviewed.

Table Diameter

The table diameter should be suitable for the workpiece and workholding system.

Load Capacity

Consider the combined weight of the workpiece, chuck, fixture and other components mounted on the rotary table.

Through Hole

The through hole can affect the type of workpieces and workholding arrangements that can be used.

Indexing Accuracy

Indexing accuracy indicates how accurately the table reaches the commanded position.

Repeatability

Repeatability indicates how consistently the rotary table can return to a specified position.

Maximum Speed

Maximum speed should match the machining process and required rotary movement.

Clamping or Braking

The required clamping or braking capability depends on the workpiece, machining forces and application.

CNC Control Compatibility

The rotary table must be compatible with the CNC machine and its control configuration.

How to Choose Between a CNC Rotary Table and CNC Index Table

Start by defining how you need the rotary axis to operate.

Ask these questions:

Do you need continuous rotary movement?
Do you mainly need positioning at defined angles?
Are you performing 4-axis machining?
How many sides of the workpiece need to be machined?
What is the workpiece size and weight?
What type of chuck or fixture will be used?
What accuracy and repeatability are required?
What CNC control system does your machine use?

The answers can help narrow down the suitable product configuration.
