Centerless Grinding - an overview ScienceDirect Topics

Mechanism of centerless grinding. With the end-feed type, the workpiece is fed axially into the machine on one side and comes to rest against an end stop; the grinding operation is performed, and then the workpiece is fed in the opposite direction to exit the machine. This type is best for tapered workpieces. In-feed centerless grinding is used to grind workpieces with relatively complex ...

Cylindrical grinder - Wikipedia

Centerless grinding is a form of grinding where there is no collet or pair of centers holding the object in place. Instead, there is a regulating wheel positioned on the opposite side of the object to the grinding wheel. A work rest keeps the object at the appropriate height but has no bearing on its rotary speed. The workblade is angled slightly towards the regulating wheel, with the ...
