Increasing the working speed of grinding wheel can significantly improve grinding efficiency and grinding ratio (for example, grinding speed of grinding wheel can be increased by 40%, grinding ratio can be doubled) and reduce grinding cost.
。 The grinding speed of metal and resin bonded diamond grinding wheels is usually 35-60 m/s (Editor-in-Chief tells you: this is the most commonly used). The grinding speed of ceramic bonded CBN grinding wheels can be increased to 45-160 m/s (this is suitable for high and large), and the grinding speed of single-layer CBN grinding wheels can be 125-250 m/s. The linear speed of 80-125 m/s has become the mainstream of CBN wheel grinding in the world. Grinding depth is generally 0.002-0.010mm (that is, it can be enlarged properly), workpiece speed is usually 10-30m/min, and longitudinal feed speed is 0.3-1.5m/min. When rough grinding, take a large value, while when fine grinding, take a small value.
