High-precision Production of Pump Rings

Whether round or out-of-round workpieces or even free-form surfaces, with the SK 204 both internal and external pump ring machining is possible: Out-of-round grinding, cylindrical grinding (internal and external), planar grinding, groove grinding and polishing – an all-around grinder.

Out-of-round Pump Ring Machining

The SK 204 was specially developed for the out-of-round machining of pump rings. Workpieces with an outer diameter of up to 250 mm can be produced on the machine. The typical range of workpieces includes rings for hydraulic pumps, cooling compressors and cam drive shaft workpieces used in injection technology.
