We are affianced in dealing a superior range of Cylinder Head Valve Lapping. It is useful when the finishing of a surface that has previously been subjected to grinding. This lapping spin the valves against the seats to make a better mating surface. Moreover, provided lapping is used to obtain very accurate surfaces. It does not require the use of holding devices. Cylinder Head Valve Lapping is designed into the engine and is most useful at higher speeds. The lapping allows air and fuel inside the cylinders to improve valves cooling and to obtain a specific surface roughness.
