Kemet offer a shoulder to lean on to take the tension out of Shaft Seal Lapping

An integral part of hydraulic and fuel system manufacturing and MRO for many years, Kemet International’s Annular Groove Lapping Systems can generate <0.001mm shoulder flatness and a surface finish of Ra 0.05µm with ease.

Most systems are based around the popular Kemet 15 bench top lapping machine, with other sizes available, and incorporate bespoke Kemet Composite Lapping plates, designed specifically for individual components. The composite plates are manufactured from a homogeneous mixture of synthetic resins, metal particles and other materials, and are produced in a variety of hardness values so that even the softest material can be lapped safely with diamond particles. Mounted on a cast iron backing plate for maximum stability, they are perfect for general and heavy-duty work where high precision flatness and surface finish are required. Used in combination with Kemet Liquid Diamond, even the most exacting tolerances can be easily achieved.

Annular Groove Lapping Systems are a must have for any aerospace MRO department. They are also available for any shoulder lapping applications: Gear faces, Aircraft hydraulic system shoulder seals and Pressure relief valve caps to name but a few. Larger systems based on the Kemet 36 have also been commissioned specifically for the medical industry where precision and process stability are essential.
