### Thrufeed Centerless OD Grinding: Parameters and ...

Apr 11, 2017 The centerless process is commonly used for high volume production, and it’s also easily used for low volume production because the machine setups are fairly simple. In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right).

More### About this site

Dec 15, 2000 Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. On traditional OD machines, the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workhead.

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.
