刀具深冷增寿美国内布拉斯加一林肯大学非传统加工工艺研究中心的研究表明，在加工一些高硬度材料时，采用液氮深冷方法叶明员降低刀具的磨损。研究人员最近测试了一种新的深冷系统在多晶立方氮化硼（＊＊＊Ｎ）和硬质合金刀片切削中的作用。该系统采用一个密封罩套，从刀... Tool Cryogenicity and Life Extension Nebraska-Lincoln University, a non-traditional processing technology research center has shown that in the processing of some high hardness materials, the use of liquid nitrogen cryogenic method Ye Mingke reduce tool wear. Researchers have recently tested the role of a new cryogenic system in the cutting of polycrystalline cubic boron nitride (*** N) and cemented carbide inserts. The system uses a sealed cover, from the knife ...
