The Lapmaster Model 15 is a bench-mounted unit with a rigid, lightweight, cast aluminum base. The machine is of the “ring lapper” configuration, enabling high standards of flatness and surface finish to be routinely achieved.
The Model 15 is derived from the popular Model 12 and features a scaled-up lapping plate, conditioning rings and convenient “wrap-around” worktable.
In - process lap plate flatness control is provided for by three conditioning rings, which locate in yoke/roller bearing assemblies. 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 15 is ideally suited for lapping low 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 from the lapping process.
The Model 15 is equally at home in the laborator y, where it can be used to process a wide variety of materials on an experimental basis. These results can then be applied to a production situation.
