Centreless grinding is an OD grinding operation where the work piece seeks its own axis of rotation between the grinding wheel and a regulating wheel. The key components in the process are the grinding wheel, the work rest blade (used to support the work) and the regulating or "feed" wheel (the drive mechanism for the work piece).

The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum Oxide abrasives are used for precision and semiprecision grinding of both mild and hard steels. The severity of the grinding operation also influences the choice of grade.
Belt grinding has become an important production process, in some cases replacing conventional grinding operations such as the grinding of camshafts. Belt speeds are usually in the range of 2,500 to 6,000 ft/min. Machines for abrasivebelt operations require proper belt support and rigid construction to minimize vibration. Grindability
In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different 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.
For surface grinding operations, the process parameters, the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground values of any of them would result in a higher material removal rate, and therefore, a .
Forms of Centerless Grinding The three forms of centerless grinding are throughfeed, endfeed, and infeed. Here is an explanation of the differences: ThroughFeed 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.
Nov 15, 2018· The grinding wheel is kept inside the work piece as it is an internal grinding operation whereas three wheels rotate outside the work piece. Pressure roll wheel applies uniform pressure from the outside and support wheel support the work piece during grinding operation. The function of the regulating wheel is the same as mentioned above.

In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.
