Efco - German Valve Grinding & Lapping Machines Get latest price

EFCO lapping machines are designed for precision machining of safety valves, ball valves, valve discs of compressors, etc.. We are manufacturer of transportable and stationary lapping machines.

Lapping belongs to the fine machining processes, with which high surface qualities, extreme form accuracies as well as narrow dimensional tolerances can be achieved.

 

Lapping is defined according to DIN 8589 and means machining with loose grain distributed in a liquid or paste. This lapping mixture is located between the workpiece and a lapping wheel. Since there is usually no heating of the lapping piece during lapping, deformation is eliminated. Many of EFCO's grinding machines can be used with lapping accessories for the precise finishing of surfaces. They are supplemented by a range of special machines for lapping.
