CNC Centerless Grinder

Provision of comprehensive grinding techniques

Total Grinding Systems

A belief that high-precision facilities are indispensable to high-precision manufacturing always accompanies our quest for rollers of higher quality. Our centerless grinders originate from that belief. The grinding techniques and know-how accumulated through the development of rollers embody our machine tools.

Why are centerless grinders recommended?

Centerless Grinder

Since centerless grinders grind workpieces without holding them by means of chucks or centers, it is possible to supply workpieces to the machines quickly. From this perspective, centerless grinders are suited to volume production. When a workpiece is loaded onto a centerless grinder, it is supported throughout its length by three planes including the surface of the grinding wheel. This manner of support makes the grinding more stable than grinding that utilizes a center support.

Angular Centerless Grinders

Angular Centerless Grinders

Tohshin Technical excels at angular centerless grinders, which have the following characteristics:

  • The high support stiffness enables highly efficient processing of long and narrow workpieces. (High productivity)
  • The relatively wide grinding wheel enables simultaneous processing of multiple locations of a workpiece along its entire length.
  • They require no center holes or dogs, which enables the processing of small workpieces that are difficult to support.
