Features
Features
The stable griding is possible for various grinding needs. It achieves high precision grinding with improving the precision and the rigidity of its mechanical structure of the spindle and feed shaft etc., and setting the minimum command unit for feed control to ⌀0.1 μm. The grinding repeatability is so stable that a change in cylindricity is just ⌀3 μm/50 mm (RD23/RD32) after 1 hour even from a cold start.
