Problems solved by technology

For this kind of silicon rod to be cut, when the old-fashioned CNC cutting machine is used to position the silicon rod with single-point forced pressure, and the cutter head tool is used for radial full-diameter cutting, the silicon rod itself is subject to great vibration, and the cutting direction cannot be in line with the silicon rod. The axis of the rod bending remains vertical, the cut part is easily broken, and it is difficult to cut out the finished product
This traditional cutting process and equipment not only caused great economic losses, but also delayed the production of the next process, which greatly increased the production cost of the enterprise.
