Deep Rolling and Roll Straightening Machines

Deep rolling and roll straightening machines - Economical crankshaft machining meets resource conservation

Deep rolling and roll straightening machines can replace hardening and bending straightening processes with resource-saving dry processing. The HEGENSCHEIDT machines are highly customized to the respective components and impress with minimal waste, reduced production costs, efficiency and sustainability.

HEGENSCHEIDT 7895 - Deep rolling and roll straightening for economical crankshaft machining 

The 7895 is a universal deep rolling machine for crankshaft machining. Deep rolling is a process in which plastic deformation of the near-surface layer induces positive three-dimensional residual compressive stresses within the bearing fillet areas of the workpiece, which is subject to the highest stress. These counteract the tensile stresses that occur under load. The material is strengthened, the surface hardness increases and the dynamic load capacity of the crankshaft is significantly increased.
