Fine turning and roller burnishing machines - surface quality and efficiency for your crankshaft series production

Fine turning combined with roller burninshing of crankshafts increases the parallelism and contact ratio of the flat surfaces and results in very good running properties.  As a result, HEGENSCHEIDT's specialized machines in this field are characterized by excellent surface quality and high efficiency, especially in series production. 

HEGENSCHEIDT 7794 - Fine turning and roller burnishing of crankshafts

The 7794 is a universal fine turning and roller burnishing machine for machining the end faces of crankshaft thrust bearings. The bearings are fine-turned and smoothed to the required length references. The precision turning operation significantly improves the parallelism of the flat surfaces due to the high machining accuracy and machining tolerance. The subsequent roller burnishing process significantly increases the contact ratio of the flat surfaces and results in very good running properties.
