Recently, our factory is remodeling large horizontal lathes. Due to the limited original travel, our factory recasts the horizontal lathe castings. At present, the hard rails are being quenched. Under traditional processes, the hard rails have poor wear resistance and precision retention, which affects the service life and processing accuracy of the lathe. We use a new quenching technology to significantly improve the surface hardness and wear resistance of the hard rails. The new process uses advanced ultrasonic induction quenching equipment to accurately control the quenching temperature and time, so that the depth and hardness uniformity of the hardened layer of the hard rails are better. At the same time, after quenching, internal Stresul poate fi eliminat, iar stabilitatea dimensională poate fi îmbunătățită . După testare, șinele dure stinse cu noul proces și -au îmbunătățit durata de viață și stabilirea prelucrării . Asigurați -vă exactitatea și fiabilitatea procesării mărului .}
