Abstract
A sintered powder metal part is prepared for machining by injecting grease into the surface of the part to be machined to a depth at least equal to the depth of machining. The grease is injected under very high pressure using repressing tooling by applying a certain volume of grease between the surface to be machined and the mating tool surface and applying pressure sufficient to uniformly inject the grease into the surface. A rim may be formed in the part adjacent to the surface which acts as a seal during grease injection and is compressed into the part.
