At present, the fast-moving wire-cutting machine used in production has a long service life, the cutting efficiency is low, the precision is deteriorated, and the high-precision mold cannot be processed on such a machine tool. Our company developed a new fast-moving wire cutting machine for the characteristics of the fast wire machine itself and the performance of the foreign slow wire machine. The machine has beautiful appearance, strong rigidity, convenient operation and high precision. Specifically, the machine has the following features. (1) In the power control, the 286 industrial control microcomputer is used, which has color display and large-capacity memory. The advanced hardware environment provides a huge use for software development and operation. With perfect, reliable and powerful software support, the power supply has a good human-machine interface and automatic control functions. Efficient pulse power supply and perfect automatic servo
