Lapping Services in Europe

Kemet Europe B.V. in Bergen op Zoom, The Netherlands have a special department for flat lapping and flat polishing of components for third parties. With this service they focus on companies who have high surface finish requirements, without having the necessary equipment to their disposal.

The Dutch lapping room covers a variety of Kemet flat lapping machines to process components with different dimensions:

• 1 x Kemet 84 conventional lapping machine. This has a cast iron serrated plate and can process parts up to 813mm diameter
• 1 x Kemet 36 diamond lapping machine. This is fitted with Kemet composite plate and can lap parts up to 368mm diameter
• 2 x Kemet 36 conventional lapping machines. This has a cast iron serrated plate and can lap parts up to 368mm diameter
• 1 x Kemet 24 diamond lapping machine. This is fitted with Kemet composite lapping plate and can process parts up to 248mm diameter
• 2 x Kemet 15 diamond lapping machine equipped with Kemet composite plates and can lap parts up to 140mm diameter

Different workpieces can be lapped such as (air-tight) seals, die casting moulds, high quality valves, motor and pump parts, flanges, components in car-, aviation- and medical industrie etc. Besides the well known steels, processing of materials such as ceramic, ferrite, hastelloy, stellite, inconel and composite materials is also possible.

Advantages of flat lapping

• Enhanced Bearing and Sliding Properties: Precision-lapped surfaces significantly reduce friction coefficients, improving mechanical efficiency and reducing power consumption in rotating and sliding applications.
• Optimised Lubrication Performance: Controlled surface topography created through precision lapping promotes uniform lubricant film formation, reducing wear rates and extending component service life dramatically.
• Superior Sealing Effectiveness: Flat-lapped mating surfaces achieve exceptional sealing performance, reducing leakage rates and improving system reliability in critical applications.
• Improved Adhesion Properties: Precision surface preparation enhances the bonding strength of protective coatings, adhesives, and surface treatments, extending component durability.
• Extended Tool Life: Precision-lapped cutting tools, stamping dies, and scraping implements demonstrate significantly longer service life due to optimised surface geometry and reduced stress concentrations.
• Cost Reduction: Improved component performance translates to reduced maintenance costs, decreased downtime, and extended replacement intervals.

Depending on the material to be lapped, Kemet Europe B.V. lap workpieces to a flatness of 1 light band (0.3 μm) and a roughness of 0.025 µm Ra or even lower. The results are measured with high precision measuring equipment.
