Surface treatment

The surface finish significantly affects the performance, fatigue strength and wear of high-speed crankshafts. Here we have gained knowledge and experience over decades. These include gas nitriding, carbonitriding, deep rolling, induction hardening and impact hardening. We have numerous proprietary, patented processes. We offer more than 60 years of practical know-how, particularly when it comes to induction hardening and stress relieving, which flows directly into the development and construction of our own hardening machines and inductors.

Finishing and assembly

After cleaning in automated car washes, the crankshafts are checked for dimensional accuracy using state-of-the-art measuring machines, automatically classified, laser-coded and prepared for dispatch. This takes place in air-conditioned clean rooms.
