motor. Smooth movement of the wheelhead delivers longer way life with
superior positioning accuracy and repeatability.
- Universal table with variable speeds can swivel +3°/-5° (G20P) and
+7°/-9° (G25P) for cylindricity corrections and taper grinding
applications.
- Slideways, leadscrews are continuously lubricated by an auto-lube
system to ensure long service life and maintain maximum accuracy.
