A centerless grinding machine is a type of grinding machine that does not require grinding of the axial center of the workpiece. It is mainly composed of three mechanisms: grinding wheel, adjusting wheel and workpiece holder. Among them, the grinding wheel actually works as a grinding machine.
Centerless grinding is the process of removing material from the outside diameter of a work piece using an abrasive wheel. In its simplest form, a centerless grinder consists of the machine base, grinding wheel, regulating wheel and work blade. With centerless grinding, the work piece is not mechanically held to drive the part.Centerless grinding is able to achieve the standard grinding goals with the added benefit of allowing for the grinding of parts that have structures and angle which would not permit them to be OD ground, and allows for the removal of three, five and several other off number lobing on the shaft of the part in question, maintaining a size and ...
Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.Widening the grind reliefs enabled the shop to finish the turned drive shaft on a centerless grinding machine rather than between centers. This made it easier and more cost effective to both achieve the listed tolerances and to maintain total indicator runout within 0.0002 inch. A part undergoes centerless grinding on a Cincinnati Cinco machine.
