Lapping Services and Contract Lapping

Our UK Lapping Technical Centre is equipped with over 15 Kemet Lapping and Polishing Machines ranging from 15" to 48" Lapping Systems allowing a fast turn-round of customers’ samples. The Centre also has Spherical Polishing Machines, along with the latest Mitutoyo Surface Measuring and Flatness Inspection Equipment. Training Courses are also available throughout the year.

If your components require optimum flatness to perform to specification, they are difficult to lap, or you have a particularly tight deadline to meet, Kemet’s sub contract service is the answer. We’re renowned for our service, reliability and quality, and we specialise in fast turnaround times.

Our expertise is wide and varied: it includes the lapping and polishing of mechanical seals, valves, compact disc mirror blocks, flat plastic mould inserts, comparator stages, spacers, cutter discs, and aircraft pump components. Our machines are equipped with both standard and special lapping plates to enable us to process most types of components. We are able to lap and/or polish components up to 530mm dia (approx 21”).

We can process most materials to a specific surface finish or flatness. Shouldered components (those with a raised centre or shaft) are also able to be lapped. All work is returned with a Certificate of Conformity covering the generated surface finish and flatness, relative to the customer’s drawing or specification. Our reputation has been built on service, reliability and quality. Fast turnaround times are our speciality.

We also have a Cleaning Technical Centre fully equipped for cleaning your parts after lapping. Our cleaners range from small Laboratory through to the latest large Mould Cleaning Systems.
