## Centerless grinding

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material is removed from the workpiece. Centerless grinding is typically used in preference to other grinding processes for operations w

## Factors affecting proper coolant application when grinding

11/08/2017 In centerless grinding, the air barrier creates the additional problem of lost friction between the regulating wheel and the workpiece. Lost friction leads to slippage between the regulating wheel and part and more frequent wheel truing to restore the worn drive surface. In all forms of grinding, wetting the wheel will allow the extreme-pressure additives in the coolant to do their job. The
