How to choose the appropriate grinding amount of grinding wheel?
The grinding speed of superhard abrasive wheel should be according to the grinding wheel type, grinding mode and cooling. The grinding efficiency and grinding ratio can be significantly improved by increasing the grinding speed of the grinding wheel (for example, the grinding speed of the grinding wheel can be increased by 40%, and the grinding ratio can be doubled) and the grinding cost can be reduced.
Metal and resin binding speed usually 15~35m/s, vitrified bond CBN grinding wheel can be improved to 45~160m/s, and the speed of single-layer CBN grinding wheel is 125~250m/s. The linear velocity of 80~125m/s has become the mainstream of CBN grinding wheel in the world.
Generally, it is 0.002~0.010mm, and the workpiece speed is 10~30m/min. The longitudinal feeding speed can be 0.3~1.5m/min. Take large value for rough grinding and small value for fine grinding.
