An electric wire cutting machine tools, and molybdenum by electric wire through the cutting of metal corrosion (especially hard materials, the complex-shaped parts).

Molybdenum wire of HS WEDM is easily broken. For solving this problem, the causes and dealing methods are present in this paper, which have a satisfactory effective in practice.

The tension of the molybdenum wire produces a direct effect on the range and the frequency of its vibration, thus affecting the quality of the wire cutting.
