Centerless Grinding. Centerless 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 diameters, smoothness and roundness.

Centerless and Cylindrical Grinding - Aztec

Cylindrical grinding is, as its name implies, the grinding of circular or cylindrical workpieces with the goal of achieving as much "roundness" of the workpiece as possible. Here, not only must the outside of a workpiece be machined accordingly, but also its inner diameter must be manufactured with extreme precision, e.g. on gear wheels.
