Drive shafts

The drive shaft within the high-pressure pump is shaped like a camshaft. The cam transmits the rotary motion of the shaft to several followers. Modern engines generate a fuel pressure of up to 2000 bar for the injection of diesel fuel.

The first step in the manufacture of the camshafts is a multistage forming of steel blanks. A number of turning, milling and drilling operations follow. The shafts get their required durability and stability through heat treatment. Final grinding and super-finishing provide for highest surface quality and accuracy of shape with a maximum tolerance of 0.003 millimeters. Every component is marked with an individual ID so that 100 percent traceability is guaranteed.
