A schematic diagram of the centerless grinding process. 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 ...
Centerless grinding. Centerless grinding: the workpiece is supported by a blade instead of by centers or chucks. Two wheels are used; the larger one is used to grind the surface of the workpiece, and the smaller wheel is used to regulate the axial movement of the workpiece.

Heim's centerless grinder was so novel at the time that many machine tool companies illegally copied and sold competing machines. Heim's machine played an important roll in the development of automatic machine tools that was recognized by the Smithsonian Institution in its exhibit on grinding during the Hall of Tools exhibition presented in 1964.
In bonded abrasive processes, the particles are held together within a matrix, and their combined shape determines the geometry of the finished workpiece. For example, in grinding the particles are bonded together in a wheel. As the grinding wheel is fed into the part, its shape is transferred onto the workpiece.
