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.

How does centerless grinding work? In centerless grinding, the workpiece is secured between two grinding wheels, with the grinding wheel rotating about a fixed axis and having a higher angular velocity compared to the workpiece. The regulating wheel applies external pressure and provides linear feed to the workpiece.

4. Centerless Grinders. Centerless grinding is a mystery to many in manufacturing because it doesn't involve using centers or gripping cylindrical parts in a chuck or fixture to grind them. No work-holding methods are needed since the part is fed between a grinding wheel and a smaller regulating wheel as it rests on an angled …

Centerless Grinding Machines. In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds. One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear ...
