Grinding is a process that produces very accurate dimensions and fine finishes. It is used to rapidly remove large volumes of metals and also for taking away small amounts of material at a time. Grinding can be used to achieve tolerances of .001”.
Centerless: In this process, the piece is supported by a workblade that is set between a regulating wheel and a high speed grinding wheel with a larger diameter. Because the workblade is sloped, the piece is above the center of wheels. This allows for accuracy without a center cut.
Lathe Turning: In this process, the diameter of the piece is reduced by turning a bar horizontally while a tool bit cuts into the piece. This results in a smooth finish and allows for custom shapes.
Grinding Between Centers: In this process, the piece is braced on each end by centers. A cylindrical grinder produces the most accurate of all grinding techniques by shaping the outside of the piece to tight tolerances.
