Centerless Grinding: Not Magic! | Modern Machine Shop
Infeed centerless grinding is analogous to plunge grinding on a center-type machine. The work is placed on the blade, and the regulating wheel moves into a programmed feed to begin the grind. The work does not move axially in this type of centerless grinding. To achieve rounding action, the workblade must be set so that the …

8 Principles of Precision Centerless Grinding
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.
