It is suitable for multi-wire cutting of single crystal silicon rods. It can cut the single crystal long rod into 6 short rods with the diamond wire cutting method, and simultaneously cut the head and tail end and take the function of the accompanying piece. The slit loss is small. The cutting speed is fast and the cutting surface size is high in precision. This machine adopts a new cutting concept and mechanical structure, equipped with a silicon rod automatic self-aligning function, and can adjust the cutting length arbitrarily without cutting the thread. Servo control technology, quick response, sensitive adjustment, large human-machine interface interaction, user-friendly operation, simple and clear, clear and easy to understand, working status at a glance, easy to operate.
