Centerless grinding

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. [1] Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; [2] the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which ...

Centerless Grinding

Centerless grinding is useful for grinding solids-of-revolution parts without the need for using centers for driving and support the workpiece. Through-feed, In-feed, and End-feed grinding are covered. In-Feed Grinding In-feed grinding differs from through-feed grinding in that the part is not fed axially so that the ground surface does not need to be a right circular cylinder.

GRINDING FEEDS AND SPEEDS

Most cylindrical grinding machines offer a rather wide range of work rotation speeds, table traverse speeds, feed rates, and, sometimes, different wheel speeds as well. The proper selection of these variables, in combination with the choice of the grinding wheel, has a great bearing on the results and the economy of the grinding operation.
