Aircraft & Aerospace Component Maintenance
The increasing demand for ever harder materials in aerospace applications presents a significant challenge in achieving precise geometries and finishes. Meeting these demands requires the most advanced and precise abrasives available in the market. In response to these challenges, Kemet Diamond Flat Lapping Systems have become the go-to solution for both original manufacturers and individual airlines for maintenance purposes. The highly efficient and reliable method of producing precision flat, polished surfaces has made Kemet Diamond Flat Lapping Systems widely used throughout the aircraft and aerospace industries.
To ensure the highest level of precision, Kemet International offers a range of ISO assured Diamond Slurries and Compounds. These products enable precision lapping of aircraft components to be performed with confidence in both 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, designed to provide optimum stock removal and surface finish, ease of cleaning, temperature resistance, and lubricity to prevent drying out.
The unique blend of diamond powder used in Kemet Diamond Slurries and Compounds has been formulated to achieve the desired surface finish and flatness on the hardest of materials. This is essential for aerospace applications where the components must meet the most stringent performance standards. The diamond particles in the slurries and compounds are precisely graded to ensure the desired level of stock removal, and their concentration is controlled to ensure a consistent and reliable result every time.
The chemical carrier in Kemet Diamond Slurries and Compounds is designed to provide a range of important features, such as lubricity to prevent drying out, high-temperature resistance, and ease of cleaning. The lubricity of the carrier is critical to achieving a consistent and high-quality finish, as it helps to prevent the diamond particles from adhering to the surface being lapped. Additionally, the high-temperature resistance of the carrier is essential for aerospace applications, where high temperatures are common, and the ease of cleaning ensures that the process remains efficient and effective.
Typical Areas
Kemet Diamond Flat Lapping systems have proven to be highly effective in a variety of industries for the precision lapping and polishing of various components. Among the typical areas where these systems are utilised are pumps and valves, hydraulic parts, engine seals and bearings, landing gear, seal manufacture and maintenance, pump manufacture, and aviation subassemblies.
For pumps and valves, metal-to-metal faced seals can be lapped using Kemet Diamond Flat Lapping systems. In addition, fuel pump gear faces can also be precisely lapped using Kemet annular grooved plates for precision shoulder lapping. These techniques have proven successful in achieving the desired flatness and surface finish of components.
In hydraulic systems, Kemet Diamond Flat Lapping systems and Kemet annular grooved plates are also used for the accurate lapping of hydraulic parts. This process ensures that the components have the correct fit and function within the hydraulic system.
Engine seals and bearings are other components that can benefit from the precise lapping and polishing offered by Kemet Diamond Flat Lapping systems. The process ensures that these components have a smooth surface, proper flatness, and optimal contact area to achieve optimal performance.
In the aviation industry, landing gear components can be effectively lapped using Kemet Diamond Flat Lapping systems. Additionally, intricate internal faces and diameters can be polished using Kemet Diamond Compound and Kemet Helilaps, ensuring that these components meet the demanding requirements of the aviation industry.
Manufacturers of mechanical seals and engine seals use Kemet Diamond Flat Lapping systems extensively in their processes. Materials commonly processed include tungsten carbide, stellite, ceramic, silicon carbide, carbon, and brass. Seal rings with diameters up to 12 inches can be lapped under production conditions to achieve mirror surfaces with flatness to 2 or 3LB.
Companies involved in the manufacture and reconditioning of pumps use Kemet Diamond Flat Lapping systems for producing and maintaining flat seal faces on mechanical seals and flow control equipment. This ensures that these components perform optimally and meet the required performance standards.
Finally, Kemet Portable hand Lap kits are used for lapping and polishing of small aircraft parts in aviation subassemblies. These kits are highly portable, making them ideal for use in the field, allowing for quick and effective repairs and maintenance.
Overall, the precision lapping and polishing capabilities of Kemet Diamond Flat Lapping systems have made them an essential tool in many industries, enabling the efficient and accurate production and maintenance of critical components.
