Lapmaster International, a recognized leader in the flat surfacing field, and International, a world leader in the formulation of ISO 9002 qualified diamond products have joined technologies to further the development of diamond surface finishing techniques. With over 45 years of flat lapping and diamond processing expertise, Lapmaster and are expanding the frontiers of precision surface finishing into virtually every industrial field.

There are many important facets to precision surface finishing with diamond. One of the most important being the size and grading of the diamond particles. Lapmaster only utilizes diamond powder graded by a refined sedimentation process, which is combined with microscopic and computer analysis to achieve an extremely tight distribution curve. Irregularly sized diamond particles may score the work surface and can degrade surface finish.

Lapmaster's diamond particles are chosen for matching size and shape so they will embed evenly into the lap plate and maximize cutting efficiency and surface finish.
