STDR 1 3 ROLLER DEVICE FOR DEEP ROLLING OF TORSION SHAFTS ON A LATHE

The deep rolling three-roller device is designed for hardening of the outer surface layer of cylindrical parts with constant or variable diameter (such as torsion shaft).
Rollers made of stamped steel are shifted to the working position with a constant
force. The maximum hardness of the workpiece is 40 HRC.
The device is designed for use on a conventional lathe.
The maximum rolling force is 1.5 tons.

Plastically deform the surface layer of the workpiece, the low compressive stress zone, by knurling polishing,
plastic deformation of the surface layer, increase fatigue resistance of parts, hardening treatment by rolling, rolling, smoothing,
hardening of the surface layer of the part, improving surface cleanliness.

Rolling is a type of machining, the purpose of which is to harden the surface layer of the part, to increase its wear resistance and to achieve 8-10 surface accuracy.
its wear resistance and achievement of 8-10 surface accuracy qualification.
Plastic deformation by roller or ball rollers and
Rollers are used for machining parts made of various plastic materials and steels with hardness not exceeding HRC 35-40.
The process proceeds without chip removal due to smoothing of the roughness obtained after turning by reducing its
size by the amount of residual deformation, the rolled hole has a correspondingly larger size. For hardening machining
The surface of the part is prepared by a method such as finishing turning.
Roughness should be within 5-6 classes of purity. It should be taken into account that the diameter of the surface in the process of hardening treatment can change up to 0,02-0,03 mm. Therefore, the outer surfaces of the part should be made to the largest size limit, and the inner - to the smallest.
