切削刀具最重要的性能是在高温下能保持的硬度、耐磨损和冲击韧性。
The most important properties of cutting tools are hardness at high temperature, wear resistance, and impact strength.
热硬度，即材料由于存在于切削区的高温而升温时仍能保持其硬度的能力。
Hot hardness, which is the ability of the material to retain its hardness at elevated temperatures in view of the high temperatures existing in the cutting zone.
重点分析了陶瓷刀具在切削淬火钢和镍基高温合金中有关切削力、切削温度、刀具磨损等方面的机理。
The mechanism of cutting force, cutting temperature and tool wear in the machining of quenched steel and nickel based high temperature alloy with ceramic tools are analyzed in the paper.
因此，刀具的硬度和它在高温下所能保持的硬度是选择切削刀具材料时的重要因素。
Hence, the hardness of the tool and the degree to which it remains its hardness at high temperature are important in the selection of a cutting-tool material.
高温加工及综合性能极好，允许切削速度较高，加工材料的硬度越高，效果越显著。
It has excellent high temperature machining and comprehensive performance, and allows higher cutting speed. The higher the hardness of machined materials, the more remarkable the effect.
