Aircraft & Aerospace Component Maintenance

With the need for ever harder materials in aerospace applications the challenge of achieving precise geometries and finishes has become ever more demanding and requires the most precise abrasives. Kemet Diamond Flat Lapping Systems are widely used throughout the aircraft and aerospace industries by both original manufacturers and individual airlines for maintenance. These systems offer the most efficient and reliable method of producing precision flat, polished surfaces.

aircraft and aerospace engineering

Kemet International’s ISO assured Diamond Slurries and Compounds enables precision lapping of aircraft components to be performed in production and service environments. Each Kemet diamond product is a special blend of diamond powder with a specific grading and concentration in a chemical carrier to give optimum stock removal and surface finish, ease of cleaning, temperature resistance and lubricity to prevent drying out.

Typical Areas

Pumps & Valves

Metal to metal faced seals can be lapped on Kemet Diamond Flat Lapping systems. While Fuel pump gear faces can be successfully lapped on Kemet annular grooved Plates for precision shoulder lapping.

Hydraulic Parts

Can be accurately lapped using Kemet Diamond Flat Lapping systems and Kemet annular Grooved Plates

Engine Seals & Bearings

Can be precisely lapped using Kemet Diamond Flat Lapping systems.

Landing Gear

Can be effectively lapped using Kemet Diamond Flat Lapping systems and intricate internal faces / diameters can be polished using Kemet Diamond Compound and Kemet Helilaps.

Seal Manufacture and Maintenance

Manufacturers for mechanical seals and engine seals use Kemet Diamond Flat Lapping Systems extensively. The most common materials processed are tungsten carbide, stellite, ceramic, silicon carbide, carbon and brass. Seal rings up to 12” diameter are successfully lapped under production conditions to have mirror surfaces with flatness to 2 or 3LB.

Pump Manufacture

Companies involved in the manufacture and reconditioning of pumps use Kemet Diamond Flat Lapping Systems for producing and maintaining / repairing flat seal faces on mechanical seals and flow control equipment

Aviation subassemblies

Kemet Portable hand Lap kits are used for lapping and polishing of small aircraft parts.
