Centerless plastic grinding is a machining process that removes material from the outside of a cylindrical item through the method of abrasive cutting in order to achieve the desired size, smoothness, and roundness. The concept is relatively simple: the workpiece is fed between two wheels rotating at different speeds, with the grinding wheel ...

Jul 01, 2020· The full process took 33 seconds, and we held the diameter to a 0.0127 mm (0.0005") tolerance and produced roundness within 0.0051 mm (0.0002"). In-feed centerless grinding, also known as plunge grinding, is conducted by placing a part on the work rest and radially feeding the part into the grinding wheel with the regulating wheel.

The plunge centerless grinding process is illustrated in Figure 3.13.The material is removed from the workpiece by advancing the control wheel at an infeedrate, v f.In some machines, the same result is achieved by advancing the grinding wheelhead.
