METHOD FOR ULTRASONIC FINISH PROCESSING OF PARTS FROM STRUCTURAL AND TOOL STEEL AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: machine building.SUBSTANCE: part is rotated and its surface is processed by an ultrasonic finish processing device with a deforming element. The ultrasonic finish processing device with a deforming element is moved along the part, is imparted with ultrasonic vibrations and multiple shock treatment by the deforming element is carried out with the ultrasonic frequency of 20 kHz and amplitude of 5-40 mcm. Herewith the deforming element and the part are partially immersed in the bath with kerosene to cool the processed part surface thus providing for the creation of gradient submicro- and nanocrystalline structures on it.EFFECT: high strength and hardness of the part surface.4 cl, 6 dwg, 1 ex
