Centreless Cylinder Grinding

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.

In centreless grinding, there are two wheels called the grinding wheel and the regulating wheel. Both wheels rotate in the same direction. The regulating wheel is smaller and rotates at lower speeds. The workpiece is placed over a work rest and th...

In centreless grinding, the workpiece is rotated by the friction between the regulating wheel and the workpiece. In cylindrical grinding, the workpiece is rotated by the headstock. P.S → There are few applications which can be done either using cylindrical or centreless grinding depending on a number of factors. Availability of the machine.

Work not straightened sufficiently before grinding Make certain it is straightened on presses before grinding. A Centreless grinder is not designed as a straightening machine although it will remove slight kinks. Insufficient stock left on piece for grinding. Allow grinding stock equal to approximately three times amount of run out.

Centerless grinding is a process that has been a part of manufacturing for nearly 100 years. It helps solve one of the limitations of other types of turning machines such as lathes and mills.

Answer (1 of 2): I hope you are asking about centreless grinding and cylindrical grinding . Well the main difference between the two is the method of holding the workpiece . In centreless grinding the workpiece is held between the Grinding wheel and regulating wheel and supported by a work rest ...

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 speed than the workpiece at the point of contact.

Forms of Centerless Grinding The three forms of centerless grinding are through-feed, end-feed, and in-feed. Here is an explanation of the differences: Through-Feed Centerless Grinding – In this process, the workpiece is fed through the center of the two grinding wheels. This technique is best used for parts that are cylindrical in shape.
