Resin diamond wire lead the industry innovation
August 5 in the morning, in the workshop of Zhejiang Rui Yi New Material Technology Co., Ltd. 10 production line is continually "spinning", a fine was difficult to identify with the naked eye. "This production is used for single, resin polycrystalline diamond wire cutting, the company now has four kinds of diamond line, where the thickest wire diameter is only 120 microns." Company officials said.
It is this stud hair-thin diamond cutting line, breaking the monopoly of foreign products and technical barriers, but also to Sweden next new materials become the country with independent intellectual property rights and to achieve resin diamond wire industrialization of high-tech enterprises. Currently, Rui Yi new material diamond wire production line 11, where 10 production lines, a test line, monthly production of about 13 million kilometers, in the case of full capacity production reached 200 million meters.
Resin diamond wire products so special? Using its cutting and what advantage? "Because of the distribution of diamond abrasive grains and grain-type uniform, damaged layer of silicon surface can be greatly reduced, to improve the accuracy of wafer cutting purposes, products with high cutting efficiency, long life and small silicon surface damage, sliced thin slice thickness consistency is good. "the person in charge, with a diameter of 120 microns diamond line, for example, damage layer thickness between 7 microns to 11 microns.
It is reported that the use of fixed resin diamond wire diamond abrasive cutting lines in high-speed rotation of the silicon rod surface cutting, to replace the current silicon carbide mortar cutting technology to solve environmental problems. "Because the resin diamond wire cutting using water-based cutting fluid to the cutting coolants, water-based cutting fluid containing only small amounts of chemicals, easy to clean, to avoid dust, water pollution and other issues, thus reducing environmental pollution." The person in charge said cooling liquid product is the company for diamond wire cutting characteristics of the resin, the independent research and development products and coolant recovery systems, recycling up diamond wire cooling liquid coolant can reduce the cost of more than 70%.
