HTF-K3 semi-automatic double-headed claw tooth grinding machine is a high-efficiency machine tool. The high-speed grinding head was originally designed as a combination of four rolling bearings in front and rear. The bearing type is 36211, D-class, and the speed is 8000r/min. The K_1180 chuck produced by our factory has a small arc radius of 12.7mm. Because it is formed by grinding, the inner circle of the grinding wheel is φ25.4mm, calculated according to 8000r/min, and the cutting line speed is 10.6m/S_0. And productivity is not going up. In this case, the grinding head speed can only be increased to 10000r/min, and the cutting line speed is increased to 13.3m/s, which is barely used for production. Due to the extreme speed of the grinding head, plus the grinding head
