The blank stamping method mainly consists in repeated cycles of blank stamping, thermal treatment, solid solution treatment; the control of heat-preserving temperature and duration, and the selection of moulds mainly takes the hardness and impact toughness values into consideration. The machining mainly comprises the control of the suitable processing parameters for milling and turning operations. The smelting method for the stainless steel material is suitable for the batchwise smelting of high nitrogen steel having a nitrogen content of 0.4 wt%-0.75 wt%; the blank stamping method inhibits the cold-work hardening phenomenon during the processing of high nitrogen steels, and facilitates the stamping of the blank; and the machining method overcomes the problem of high processing difficulty due to the great hardness of high nitrogen steel.

A hot-wire cutter includes a frame, a tank supported on the frame, a first working head located on a floor of the tank, a second working head movably supported on the frame, a supporting unit supported on the frame and used to support an annular work piece, a restraining unit supported on the frame and used to clamp the annular work piece, and a rotating unit supported on the frame and used to rotate the annular work piece. Thus, a line between the first and second working heads is directed through the centers of initial apertures in the annular work piece, one after another, to facilitate precise processing of sections of the annular work piece corresponding to the initial apertures.
