Lapping

Lapping is a precise machining process that is used in metal processing and other branches of industry. In this process, an abrasive-coated tool surface, the so-called lapping tool, is moved in a circular or reciprocating motion over the surface to be machined.

The main purpose of lapping is to improve the surface quality and achieve high flatness and parallelism tolerances. Lapping can be used for both flat and curved surfaces and is widely used in the manufacture of precision parts, tools and machine components.

During the lapping process, an abrasive, often in the form of a paste or suspension, is placed between the lapping tool and the workpiece surface. Due to the relatively soft nature of the abrasive, even the smallest irregularities on the workpiece surface can be removed, resulting in a significant improvement in surface quality.

A characteristic feature of lapping is the ability to achieve high-precision tolerances. By controlling pressure, movement and abrasive, the finest unevenness on the workpiece surface can be eliminated, resulting in an extremely smooth surface. This makes lapping particularly suitable for applications where the highest precision and quality are required, for example in the manufacture of precision bearings, seals and optical components. Overall, lapping helps to improve the quality of machine components and increase the performance of components by enabling the exact machining of surfaces.
