Grinding is a less controllable process than other areas of manufacturing because of the use of a grinding wheel for metal removal. The grinding wheel is a cutting media that is constantly breaking down and changing. It actually changes its grinding characteristics as it grinds.

This page describes the technology of centreless (centerless) grinding as well as centreless (centerless) grinding machines from Koyo Machine Industries. With centreless (centerless) grinders, a workpiece is supported by a work rest blade and set between a rubber regulating wheel that rotates the workpiece and a rotating grinding wheel.

Grinding is no exception. So, while Makino machining centers are helping manufacturers cut cost and time by minimizing non-cut time, setup time and tool-changing time, new technologies that combine grinding and milling in one setup in one machine are also reducing part cycle times by as much as 75 percent. Better, faster, more cost-effective.
