Machine tool is mainly used for the outer surface of the bearing ring grinding processing, CNC bearing grinding machine is a new generation of high-precision, high-efficiency production-type machine tools. CNC bearing grinding machine is particularly applicable to small batch and high-volume production. High-speed grinding of CNC bearing grinding machine is a kind of grinding technology whose grinding wheel speed is more than 45m / s. In the 1960s, the United States mainly produced 60m / s high-speed grinding machine, because of its high grinding power, good surface quality And grinding wheel wear a low-level strengths, has become an important development path. Practice is generally believed that the economy of high-speed grinding speed is 50 to 60 m / s, the speed of the original state of the machine better only some of the appropriate modifications are easy to complete, the domestic production in the promotion and application.
