Hegenscheidt Deep Rolling and Straightening Machines
Hegenscheidt-MFD has been at the forefront of deep rolling technology development since its introduction to the automotive industry in 1957.
The crankshaft fillet deep rolling process induces residual compressive stresses into the fillet radii, increasing the fatigue limit and significantly increasing the service life of the work piece. The deep rolling process offers an economical and capable method of optimizing the fatigue strength of high performance crankshafts in high volume production environments.
This technology was perfected by using angle-dependent deep rolling as well as roll-straightening processes. Roll straightening reduces the radial runout present in the crankshaft. Several patents were granted to Hegenscheidt and the NSH Group for the technologies and machine designs introduced between the early development and the levels achieved today. The innovative crankshaft machining technology applied nowadays in the automotive industry for compact motors was pivotal both in achieving material savings and in improving quality and service life.
