Hydraulic/Pneumatic

The MICROFINISH method, also known as Superfinish, has proved itself with economic fine machining of thrust and sealing faces for pump rotors, cog wheels, pump covers, and pistons.

The workpieces can often be machined on both sides simultaneously. With such precise functional faces, high operating pressures may be realized in the respective assemblies.


Furthermore, MICROFINISH can be used for fine machining of ball valves, sealing seats, shafts, plane, and spherical surfaces. Valves with finished ball valves made of steel and other materials (e.g. ceramics) meet the highest demand for safety and environmental protection under all kinds of operating conditions and are used both in oil pipelines, reactor constructions, and in the chemical industry.

Perfect geometric form and surface quality ensure highest operational safety and a long life.
