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 7625 - Flexible machining of large crankshafts up to 4000mm length

The 7625 is a HEGENSCHEIDT deep rolling and roll straightening machine for machining large crankshafts up to 4000 mm in length, for example for emergency power generators, marine or diesel engines as well as construction machinery and commercial vehicles. The special machine, which is designed to tto the requirements of the market, provides an economical, energy- and resource-saving process for increasing the fatigue strength of crankshafts and minimising the radial run-out of main bearings.

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.
