Jainnher

With an increased wheel size over the JHC 18S, this machine has a 305mm wide grinding wheel on this model with a 455mm diameter allows for components to be ground from 1 to 50mm with a standard workrest and 40 to 100mm with a special workrest.
The advantages of centreless grinding, are not just for high volume production. Centreless grinding provides a fast turnaround for rounding of stock material and quite often, suits lower production runs. Tight tolerances easily achievable. All spindles fitted with precision ground Hydrostatic Bearings with a high pressure oil film for added precision under heavy
loads.

The next model up from the JHC 18S, this machine has a 255mm wide grinding wheel on this model with a 455mm diameter allows for components to be ground from 1 to 50mm with a standard workrest and 40 to 100mm with a special workrest. The EUROPA Jainnhers grinding wheel spindle runs on hydrostatic bearings with a high-pressure oil film for added precision under heavy loads 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

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.
