Precision Surfacing Solutions Bench Top Lapping/Polishing Machine Model 20

The Lapmaster model 20 (pneumatic lift) is a bench-mounted unit with a heavy duty, carbon steel weldment base. The machine is of the “ring lapper” or “planetary lapper” configuration, enabling high standards of flatness and surface finish to be routinely achieved.

The model 20 is derived from the popular model 12 and 15 machines but features a steel weldment base instead of cast aluminium. A scaled-up lapping plate, conditioning rings and convenient “wrap-around” worktable combine to form a unique package. (The model 20 is the largest bench-mounted machine in the USA offered by any company.)

The machine is equipped with a pneumatic system for prescribed down pressure adjustment on workpieces. The pneumatic system incorporates OSHA control circuitry and air logic which provides total operator safety through two-hand, anti-tie down operation of the pressure plates.

In-process lap plate flatness control is provided for by three conditioning rings, which locate in yokes fitted with roller bearings. Workpieces are located within carriers or appropriate fixtures which run within the rings. Large parts of cylindrical shape can be substituted for the rings.

The model 20 is ideally suited for lapping normal and high production quantities. In-shop lapping reduces costs of component processing and equipment maintenance programs. Worn parts are reconditioned and salvaged, thus eliminating scrap. Valve bodies, discs, gears, vanes, valve plates and shaft seals are a few of the components benefiting form the lapping process.

The model 20 is equally at home in the laboratory, processing diverse materials such as semiconductors, electro-optics, optics and ceramics. This machine is also available in a open face version. See appropriate data sheet.
