Centerless Grinding

Centerless grinding is an abrasive machining process by which small chips of material are removed from the external surface of a cylindrical metallic or nonmetallic workpiece.  This process relies on the relative rotations of the grinding wheel and regulating wheel to rotate the workpiece.  The process does not require chucking or locating the workpiece between centers for rotation.

Process Characteristics

Requires no chucking or mounting of the workpiece
Produces close tolerances and smooth surfaces
Is applicable for cylindrical, stepped, formed, and conical workpieces
Is most efficient for through-feed operations
Requires coolant
Is primarily a finishing process
