Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

Define Lapping and How it works: Lapping Involves the Use of Abrasive Particles to Modify the Work-Pieces. The Abrasive Particles are Mixed with a Water-Base or Oil Base Liquid. The Combined Abrasive and Liquid are Called a "Slurry", this is a Liquid Cutting Tool. The Slurry is Placed on a Rotating Motorized Platform Called a "Lap Plate".

Wheel blasting or peening equipment, directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. With these large amounts of accelerated abrasive, wheel blast machines are used where big parts or large areas of parts have to be de-rusted, descaled, de-burred, de-sanded or cleaned in some form prior to coating.
