The influence of technological parameters process burnishing on the reduce roughness steel shaft

The processing is burnishing one from the methods of processing finishing off the metals, depending on utilization the local plastic deformation, produced in top layer of object as a result of definite, meeting co-operation hard the and smooth tool from worked surface. The plastic deformations are called out by arrangement of strengths causing the superficial crossing the value of tension pressures of the making plastic material worked. Set them on cold causing except moving the unevenness also the cold work in top layer of worked object. The effect of moving ("flowing") the unevenness of surface, as a result of influence on worked surface smooth the and hard tool, it is the decrease of roughness of surface worked, however the effect the cold work - the principal change of property of top layer object. Phenomena these, though they step out the most often simultaneously, can have different intensity, according from demanded main effect of processing. It can be with main aim of applying processing the burnishing in technology of machines: the smoothness processing - the definite decrease the height not the equality of surface after previous processing burnishing; the strengthening processing - the producing of definite changes of physical properties of material in top layer of object, causing immunizing him on working such exploational factors how fatigue, abrasive waste, corrosion and different; the processing the dimensional - smoothness - the definite enlargement the dimension exactitude from simultaneous decrease to required value the roughness of surface. The determination of influence of technological parameters process burnishing on quality of surface of rolls from stainless and unalloyed steel is the aim of work
