NEW JAINNHER JHC-12S

With a capacity from 1 to 25mm with a standard workrest or 25 to 40mm with a special workrest, and a servo controlled regulating wheel, the JHC 12S is the most compact centreless grinder in the range.
A precision ground, the hydrostatic bearing assembly provides minimal friction and lateral displacement, along with extended wheel life under heavy grinding loads. The grinding wheel spindle runs on the hydrostatic bearings with an ultra-thin oil film between all touching surfaces. This provides a substantial reduction in wear and prolongs spindle trueness and longevity. The regulating wheel uses a Variable Speed Motor, controls the speed of the regulating wheel.
