到目前为止,在磨具所有的物理机械性能中,能在较大程度上反映磨具磨削性能的,仍然首推硬度。对于硬度的含义及其测定方法,数十年来,各个国家都进行了大量的研究,硬度的定义,至今尚未有定论。至于测定方法的研究,则从最简单的刻痕法,直至近年出现的 So far, all of the physical and mechanical properties of the abrasive, to a greater extent reflect the abrasive grinding performance, the hardness is still the most important. For the meaning of hardness and its determination method, for decades, various countries have carried out a large number of studies, the definition of hardness, has not yet been conclusive. As for the determination of the method of study, from the most simple scoring method until recent years
