| 摘 要： | 黑色金属的超精密切削问题一直是超精加工领域中未能解决的难题。本文提出了在超低温状态下用天然金刚石单晶车刀超精密切削黑色金属的新工艺，为解决这个难题开辟了新的途径。实验结果表明，在超低温状态下，金刚石车刀切钢时的急剧磨损可以有效地被抑制，刀具寿命增加，从而使黑色金属的金刚石超精密切削成为可能。

| Abstract: | It is known to all that natural diamond tool can not be used in ultra-precision Machining ferrous metals, such as steel, iron and manganese. The technical barrier is that the tool wear rate is too high to be accepted. In order to reduce the tool wear, proceed from controlling the cutting temperature, the authors advanced a new working technology Cryogenic machining ferrous metals with natural diamond tools. Our experimental results have demonstrated that the wear of diamond tool can be effectively, restrainted at cryogenic condition so that it is possible to cut ferrous metals with diamond tool by cryogenic machining, which is a breakthrough in ultra-precision machining. |
