Metal lapping

Metal lapping: the process of precision finishing on metal surfaces

Metal lapping is a precision finishing process for metal surfaces, performed with brushes that use the action of a sprinkled abrasive powder onto a metal support, often in a similar shape to that of the object to be lapped. Metal lapping is often used to create a smooth, polished finish on metal surfaces. It can also be used to achieve a precise level of tolerance in the machining of metal parts.

Metal lapping: functions and advantages

Metal lapping is carried out to reduce to a minimum the surface roughness, obtaining a “mirror” finish. Performed in many sectors where these materials are used, metal lapping has both for functional and aesthetic purposes.  This process must be carried out with maximum precision with specific machinery, so as to obtain a uniform mirror finish without damaging the surface of the raw material.

Metal lapping machines: standard and custom-made solution to increase and improve productivity

Metal lapping requires specific metal lapping machines to obtain precise and high quality results. A metal lapping machine is a machine specifically designed to smooth the surface of a metal object by rubbing it with a rotating abrasive wheel. The machine can be used to remove burrs from metal objects, to smooth out scratches, or to give the object a polished finish. These machines are available in a variety of sizes and can be used for a wide range of metal objects in different industrial sectors.


Volpato offers standard finishing machines that can carry out this type of process, but is also specialized in customized metal lapping machines. The design and development of all machinery is entrusted to a team of experts who work with passion and professionalism to offer tailor-made solutions, perfectly suited to your production line. Another strong point of the company’s design service is the opportunity to test out the performance of the machine with materials normally used within your company.
