Compare two- and three-station rotary-table configurations for multi-workpiece machining setups. Confirm the complete model, station layout, workpiece envelope and machine integration before selection.
VRNC 2W / 3W model comparison
2W and 3W identify the number of rotary-table stations in the catalogue. They do not establish independently controlled axes or machine/control compatibility.
| Model | Table diameter (mm) | Vertical center height (mm) | Indexing accuracy (arc sec) | Maximum speed (rpm) | Net weight, motor excluded (kg) |
|---|---|---|---|---|---|
| VRNC-A125-2W | 125 | 150 | 40 | 44.4 | 88 |
| VRNC-A125-3W | 125 | 150 | 40 | 44.4 | 128 |
| VRNC-170-2W | 170 | 180 | 20 | 33.3 | 137 |
| VRNC-170-3W | 170 | 180 | 20 | 33.3 | 210 |
| VRNC-210-2W | 210 | 205 | 20 | 33.3 | 153 |
| VRNC-210-3W | 210 | 205 | 20 | 33.3 | 234 |
Catalogue references: minimum input increment 0.001°, repeatability 4 arc sec, reduction ratio 1/90. The minimum increment is not indexing accuracy. Verify current specifications against the accepted configuration and drawing.
Two stations or three?
Compare station spacing, full installed width, fixture and part interference, tool access and the complete machine-table payload. Additional stations do not by themselves establish higher production output for your process.
Review each station’s workpiece and fixture load
The catalogue gives different per-station load values for 2W and 3W configurations. Do not use a single-station model’s rating or divide a total rating equally without reviewing the specified configuration. Send the mass and load offset for every station, and identify any tailstock support.
Machine integration requirements
- Machine model, CNC control and enabled rotary-axis functions
- Required station count, motion and machining cycle
- Part and fixture dimensions, mass and load offset at each station
- Mounting space, station spacing and swept envelope
- Drive/motor/encoder interfaces, pneumatic supply and installation scope
Need support at the opposite end?
Tailstock selection depends on the paired rotary unit, center alignment and fixture arrangement.
