Beaver Lapping Compound is a silicon carbide grease base lapping compound. Silicon carbide is a very sharp pointed abrasive grain that continually breaks down to leave a fine finish. The petroleum base vehicle keeps the abrasive in suspension therefore no mixing is required.
In the lapping slurry (Fig. 7c), we found the blunt coarse and ultra-fine diamond chips, suggesting that during lapping these coarse and ultra-fine diamond particles did fall off from the FADA pad. As illustrated in Fig. 8 b, the fall-off of diamond grains from AD abrasives allow diamond grains buried underneath the blunt diamond grains with ...

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.
