随着CBN在砂轮制造中的应用,由一种结实的基体材料和最大厚度为10mm的CBN磨料层制成的砂轮,可将速度提高到250m/s。但是它们当时的速度极限并不是由其经济标准所决定的。磨床的心轴驱动系统、保护装置,以及砂轮的断裂强度都提高了其极限。Krug先生预言六十四年后的今天,电镀结合剂CBN砂轮的磨削速度为200～250m/s,可以看作是 With the CBN used in grinding wheel manufacture, the grinding wheel made of a solid matrix material and CBN abrasive layer with a maximum thickness of 10 mm can be increased to 250 m / s. But their speed limit at that time was not determined by their economic standards. Grinding machine spindle drive system, protection devices, as well as the breaking strength of the wheel have raised their limits. Krug predicts that today, sixty-four years later, the grinding speed of the electroplated CBN grinding wheel is 200 ~ 250m / s, which can be regarded as
