After years of research and development, Jiangxi Province's strategic emerging industry R & D and guiding project "ultra-thin diamond wire wafer cutting machine" project successfully completed various tasks, and held a project acceptance meeting in Pingxiang on August 22.

After listening to the project report, watching live demonstrations, reviewing relevant materials and questioning and discussing, the nine experts composed of Professor Duan Zhengcheng, a professor of Huazhong University of Science and Technology, agreed that the aircraft was the first ultra-thin (120um) King Kong in China. Line wafer cutting machine, the price is 50% of the foreign similar products, the comprehensive technical performance has reached the international advanced level of similar products, will break the monopoly of the diamond wire cutting machine in the foreign market, accelerate the photovoltaic industry diamond wire cutting technology to replace the traditional free Upgrade of the type (mortar) cutting technology to achieve green production.

The project has developed a system for the technology and process of ultra-thin diamond wire wafer cutting machine, such as the overall structure, automatic control system, ultra-thin wafer cutting, etc., using two spindle roller structures to reduce the occurrence of wire jumpers. The stability of the equipment is improved; the distortion of the diamond wire during the transition is reduced by the optimized design of the winding system; the real-time monitoring and cutting speed and feed of the machining process are realized through the optimized design of the control system. The coordinated control of speed improves the cutting ability and reliability of the equipment; the ultrasonic automatic filtering system is added to improve the utilization rate of the cutting fluid.

Leaders and experts from China Electronics Technology Group, Huazhong University of Science and Technology, Jiangxi Science and Technology Department, Nanchang University, Central South University, Jiangxi Normal University, Jiangxi Provincial Machinery Industry Office, Jiangxi Mining Machinery Research Institute, Pingxiang Municipal Government and relevant departments of the municipal government Attend the acceptance meeting.

Disperse Yellow series include Disperse Yellow 114, Disperse Yellow 211, Disperse Yellow 119, Disperse Yellow 54, disperse yellow 42, disperse yellow 56, disperse yellow ERGFL etc.
