They have named their procedure "Microcut Bore Sizing". Put simply, it's all about touching up the tiniest boreholes. And when we say tiny, we mean tiny: We are talking about dimensions in the micrometer range. The smallest boreholes measure a mere 0.015 millimeters - not even a human hair could fit through them.

During the cutting process heat from friction is absorbed and carried off by the discarded metal chips thus resulting in improved accuracy and excellent surface finish. The surface finish is then checked by using the Mitutoyo SJ-301.

The purpose of cam grinding is to maintain close to the same clearance when hot and cold. With proper piston design, you would have between .001 and .002 thou. clearance when cold, for instance. When heated up, the piston expands along the length of the wrist pin and the clearance perpendicular to the pin stays the same.
