There are two basic forms of abrasive wear: two-body abrasion and three-body abrasion. A simple description of two-body abrasion would be a hard, rotating surface cutting into a soft, fixed surface, like a shaft running over a sleeve bearing. Imagine taking a car key to the side of a car. The key rips into the car’s surface, causing damage.

Nip points between rotating elements and parts with longitudinal motions. Nip points can occur between rotating and fixed parts which create a shearing, crushing, or abrading action. Examples are: spoked handwheels or flywheels, screw conveyors, or the periphery of an abrasive wheel and an incorrectly adjusted work rest and tongue.

The heart of the technique is to get the loose abrasive to roll between the plates and not skid, and getting the amount of liquid just right makes a big difference in how the abrasive works. Too much or little and it will want to skid vs roll. Also, keep the pressure light so you don''t break the abrasive down faster.
