PROCESSING OF INTERNAL CYLINDRICAL SURFACES ROLLING WITH HEATING
Machining internal cylindrical surfaces with heat nakatyvaniem, compared with nakatyvaniem in the cold, is a promising process of technological processing of high mobility of repair and reconstruction works in remote environments. In the process of surface finishing internal holes nakatnym roller with the heating of a gas burner flame holes. According to the results of tests and studies found that when fashion with heating decreases the roughness of the surface microstructure of grains deformation occurs, the surface layer of the material, which increases its density and resistance to educational opportunities razgarnyh cracks when pulsed thermal effects. The hot rolling is advisable to use as thermo-mechanical operation to impart a desired roughness, holes highly loaded structures operating in harsh climatic conditions.
