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 …
Centerless grinding is a machining process that uses abrasive cutting as a means for stock removal. What distinguishes centerless grinders from centered grinders is the absence of a spindle or fixture to secure the workpiece in place. The workpiece is secured between two wheels - a grinding wheel and a regulating wheel.
