Pressure flow lapping

Pressure flow lapping is a precise surface engineering process used to finish and refine the surfaces of workpieces to the highest standards. This process is used in various industries, including automotive, aerospace, medical and precision component manufacturing.

In pressure flow lapping, a workpiece that requires a high-quality finish is clamped in a special fixture. An abrasive paste or lapping compound containing abrasive particles is applied to the surface to be machined. A second surface, also abrasive, often in the form of a tool or disc, is applied to the workpiece with pressure and set in an oscillating or rotating motion.

During this process, the abrasive particles move between the two surfaces and remove material from the workpiece surface. This is done extremely precisely and evenly, machining the surface of the workpiece layer by layer. The result is an extremely smooth and high-precision surface with very low roughness.

Pressure flow lapping offers a variety of advantages, including the ability to create surfaces with very tight tolerances, achieve high flatness and parallelism, and significantly improve surface finish. It is also effective in removing surface defects such as burrs, grooves or microstructures.

This process is widely used on high-precision components, such as bearings, valves, gear parts, seals and medical instruments. It helps improve the life, functionality and reliability of these components. In addition, pressure flow lapping can help reduce energy consumption in mechanical systems by minimizing friction and wear due to the high-quality surfaces.

In summary, pressure flow lapping is a high-precision surface engineering process used to finish and refine surfaces to the highest standards. It contributes to the manufacture of precision components and products that must meet stringent requirements for surface finish and precision, and is therefore used in a wide range of applications.
