Centerless Basics A centerless grinder has three main components: a grinding wheel, a regulat-ing wheel and a work support blade. Be-cause the entire workpiece is supported by the regulating wheel and the blade, centerless grinding provides a more rigid system, enabling more efficient and ac-curate grinding compared to grinding between centers.

May 03, 2008 · Re: Centerless Grinding (SPC) This chart is a classic example of a gage that has inadequate resolution to see the process variation. The true process variation is probably stable with the one exception where the wheel was dressed. If SPC is a requirement for this process, you will need a gage with better resolution.

These elements can be arranged in different ways for different types of centreless grinding but the fundamental principle of the centreless grinding process remains the same. A combination of forces (the cutting pressure of the grinding wheel and gravity acting on the work) keep the work in contact with the work rest blade and the regulating wheel.
