Europa Jainnher JHC 20S Centerless Grinding Machine


With a standard work capacity from 1mm to 50mm with a standard work rest, and 40mm to 100mm with a special workrest. A servo motor provides control of speeds from 10 to 250rpm and is used for the regulating wheel, which can be adjusted to ideal linear speeds. When the diameter of the regulating wheel changes the same linear speeds can still be maintained so as grind the best quality products. NC & CNC models available.

Hydrostatic Bearings: Precision ground Hydrostatic Bearings: Substantial decrease in heat deformation associated with Hydrodynamic bearings.Minimal friction, lateral displacement, and pressure .Extended tool life under heavy cut loads.

Grinding Wheel Spindle: The Grinding Wheel Spindle runs on hydrostatic bearings with a high-pressure oil film for added precision under heavy loads. Substantially reduces wear while prolonging spindle trueness. SNCM-210H carbon steel hardened beyond HRC60, yielding high torsion resistance.
