Description

Adding molybdenum to alloy steel can improve the elastic limit of the metal, corrosion resistance, and permanent magnetism, etc. The packaging of super-power thyristors adopts a compression process, and the chips of high-voltage and large-current semiconductor devices are matched with alloy molybdenum discs and use full compression technology to be packaged in a ceramic tube shell. Therefore, a series of processing treatments need to be performed on the molybdenum disc before use, including cutting treatment of the molybdenum disc.

[0003] According to the patent document with the patent number CN106735592A, the molybdenum disc is fully cut by using ultra-high water flow cutting technology, so that the surface smoothness of the cut molybdenum disc is higher.

This not only affects the performance and life of the cutting tool, but also can affect the machining precision and surface quality. The bottom of the molybdenum disc cannot be soaked for cooling during the cutting process, and the spraying of cutting fluid cannot achieve the best cooling effect.
