- Easy changeover on an expansion arbor without changing the lathe chuck - High-precision clamping of smallest inner diameters
- Visual safety devices - Maximum operating safety
- Ergonomic, light safety spanner wrench - Ensures easy operation
- All functional parts are ground and hardened - High run-out and jaw change repeat accuracy
To clamp small inner clamping diameters, the ROTA-S plus 2.0 in sizes 200 and 250 can be supplemented with a vario M arbor. The vario M arbor is available in four sizes, and can precisely clamp inner diameters from 20 - 80 mm. The vario M arbor can be directly fastened to the lathe chuck. The set-up process takes less than 5 minutes.
