STR3-04 ROLLER RUN-IN FOR RUNNING-IN WHEELSETS
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 to process parts made of various plastic materials.
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 such method 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.
