Lapping is an improvement compared to grinding, as the lapping machine works with loose abrasives. Its finishing allows the highest surface quality. Although a distinction is made between single- and double-sided machines, and there are many forms of lapping, the basic principle remains the same: a paste or liquid (lapping agent) containing lapping abrasives is added to the gap between the lapping tool and the workpiece. The removal process takes place as a result of the movement between the abrasive and the workpiece. Lapping machines are very popular even as used machines.

The lapping process is a cutting manufacturing process, which is mainly used for finishing, and for the final production stages of a product. It can be compared to smoothing or polishing, because the lapping works with granular material.

Contrary to smoothing and polishing processes, the granules used during the lapping process are free and mobile. They continuously move between the workpiece and a pressure disc during the lapping process. An exception to this is during slurry sawing, which combines a separation and a lapping process. However, finishing is not applicable, as this stage is usually included as a step within the separation process. Other types of lapping include spherical lapping, cylindrical lapping, lead screw lapping and more. Each type of lapping results in an incredibly accurate surface area, with precision levels of up to a micrometer.

Lapping is required in metalworking section for products that have particular requirements for dimensional accuracy and surface quality. Typical workpieces that require lapping include gear pumps, paddle wheels for turbochargers and tools for the aviation and aerospace industry. Lapping is the highest form of mechanical surface processing available and with its high level of production quality (which is so good, it can hardly be increased), it provides expert results.

High levels of experience are necessary for working with a lapping machine, since they work in margins of a micrometer. Assistants should not work with the machine without intensive education and training. It is particularly important for the user of a lapping machine to recognise the necessity of precision, otherwise there is a danger of tolerance thresholds being ignored. Technically, lapping machines are not particularly complex, but they do have very sophisticated components. The uniform, quiet and continuous movement of the lapping machine can only occur when using high-end tools. Therefore, it is not possible to find cheap lapping machines. It is advisable to take specific care that the machine and its surroundings are kept suitably clean. Lapping machines are incredibly sensitive to high levels of dirtiness. A machine that produces dust and chippings should not be placed next to the lapping machine. The regular and diligent cleaning of a lapping machine will have a direct impact on its production quality. For this reason, lapping machines are a favourite machine for special facilities that focus solely on final stages of production.

Lapping machines are special machines and are not part of the range of standard machines used by mechanical engineers. Established providers of lapping machines are MAW WERKZEUGMASCHINEN, FLP MICROFINISHING, MYTECH GRÄVEN GmbH, BRINKMANN + WECKER GmbH and PETER WOLTERS.
