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

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.
