Hypro Lapping
Hypro Lapping

The Hypro lap creates flatness on warped or distorted surfaces. Our hypro lap equipment is particularly adept at finishing non-magnetic materials when a high surface finish is required. Hypro lapping also has an impressively high production rate and can deliver finishes to 5 micro-inches, including tolerances to .0002″ flat and parallel within the same limit. Thin, small and odd-shaped parts, with a maximum diameter of 8″ can also be ground

Micro lapping and loose abrasive lapping is available using a wide variety of compounds and slurries. Lapping and polishing is used to achieve a specific surface finish, flatness and parallelism. During the lapping process, revolving flat surfaces abrade the ceramic part with a diamond or other abrasive lapping compound.

The surface finish is controlled through selection of the proper abrasive, pressure and lapping cycle. U.G.C. regularly works with a wide variety of materials, providing precision lapping and polishing for low volume custom jobs to high volume production. Whether lapping for stringent control of flatness or reducing thickness to provide a substrate commercially unavailable, our experience dates back to the early ’40s.
