Centerless grinding Wikipedia

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

Centerless Grinding an overview ScienceDirect Topics

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.

Centerless Grinding

Centerless grinding is a very effective way of saving time and money on finishing parts.Tolerances of .0001 or less can be held on diameters ranging from .005 to 3.500 and lengths from 1/4" to 15 ft. long. There are two types of centerless grinding, thru-feed and infeed. When thru-feed grinding, the work goes in one side of the machine and
