With the in-feed method, the regulating wheel spins the part at one speed while pushing it towards the grinding wheel, which is spinning at a faster speed. The greater the difference in speeds, the faster the removal rate. 4. The choice of grinding wheel is critical. Another key factor in centerless grinding is the choice of grinding wheel.

Wheel Grade. This determines the tightness of the bonds holding the abrasives. The wheel grade affects all the considerations of grinding. This includes wheel speed, coolant flow, feed rates, and grinding depth. Grain Spacing. This depends on the spacing of the structure. It determines the ratio of the bond and the abrasive to the air space.
