GRINDING AND OTHER ABRASIVE PROCESSES
centerless grinding consists of two wheels; the grinding wheel and a regulating wheel. The workparts, which may be many individual short pieces or long rods (e.g.,3-4m long), are supported by a rest blade and fed through between the two wheels. The grinding wheel does the cutting, rotating at surface speeds of 1200-1800 m/min (4000-6000 ft/min).

Honing Process - Working, Diagram, Advantages, Applications
Honing uses a large contact area at a slow speed compared with grinding or fine boring, which uses a small contact area at high speed. Because of the combined rotating and reciprocating motion used, a crosshatched pattern is created which is excellent for holding lubrication.

Lapping generates flat surfaces (geometry refinement) with extremely fine finishes using lapping compound, where parts are processed between one or two large flat lap plates or platens. Lapping is a gentle surfacing process using low speeds (80 RPM) and low pressures. Compared to grinding and honing, lapping removes much less material.
