Experimental Research on Ultrasonic Vibration Finishing Performance of 9 Cr18 Bearing Steel
Ultrasonic vibration finishing is carried out on the 9 Cr18 bearing steel samples of typical difficult-to-machine materials for aircrafts.Through the tests of surface residual stress,micro-hardness,tensile properties at room temperature,fatigue properties,and microstructures,this paper explores the influence of ultrasonic vibration finishing on the cutting performance and structure fatigue life of typical difficult-to-machine materials of aircraft,and provides a new preparation process plan to meet the long-life design indicators proposed by airframe structure of the new generation aircraft.
