With light rare earth content is 0. 1%wt,WC-0. 1RE-10Co cemented carbide mixture vacuum sintering at 1 380℃,preparation of CNMG - 120408 type of turning tool. After sandblasting and ultrasonic cleaning,TiAlN coatings were deposited by magnetron sputtering process on the tool surface. Microstructure observation and cutting performance experiment were carried out on the coated tools. The results show that:the addition of light rare earth help to increase the adhesion strength of the coating and substrate,prolong service life and decrease the cost of the preparation.
