What's the grinding process?

Grinding is a process to make the metallic surface smooth by whetstone. Other than using a whetstone, a film called paper-wrap is used for fine surface finish. By finishing the surface smoothly, friction can be reduced.

We do grinding for not only connecting rods and crankshafts, but also shafts used in air-conditioners as well.

Technology of Fujita Iron Works Co., Ltd.

In order to make parts with micro dimensional requirements which our customers ask us to make, we equipped a regular inner bore grinder with a NC controller and we use brand-new horning machines and CNC eccentrical pin / Polygon horning machines and angular cylinder grinding machines. We have internally designed paper wrapping machines too.
