High-efficiency precision gear grinding machine has complex technology and high barriers to entry. At present, only a few countries such as Germany, Switzerland and the United States have the ability to develop and mass produce. Europe and the United States, Japan's high-end car transmission gears and some heavy-duty truck transmission gears widely use grinding technology, China's previous production of gear grinding machine, processing precision, processing efficiency, reliability and software functions and other aspects of the international advanced gear grinding machine The gap can not meet the demand for high-efficiency machining of precision gears in the domestic automotive, aerospace and other industries. High-efficiency precision gear grinding machines are monopolized by foreign countries, and key technologies are blocked by foreign countries.
Chongqing Machine Tool Group has established the National Certified Enterprise Technology Center and the European Machine Tool R&D Center. It is the cradle of China's gear processing machine tools and the largest manufacturer of gear processing machines in the world.
The YW7232CNC high-efficiency precision gear grinding machine independently developed by the company has overcome more than ten key technical problems such as high-speed direct drive, automatic balancing of high-speed spindle, automatic dressing of grinding wheel, high-speed automatic tooth matching and automatic detection of grinding wheel life. And software, man-machine dialogue control software (HMI) for research and development, mastered the main software functions of grinding teeth; research and verification of the grinding process, the machine uses worm wheel grinding, the maximum processing diameter is ф320mm, the maximum processing modulus 8mm, the maximum speed of the grinding wheel spindle reaches 10000r/min, the maximum speed of the working table reaches 1000r/min, the linear speed of the grinding wheel is up to 80m/s, and the precision of precision grinding gear reaches the level 3 of GB/T10095-2008; the technical level of the whole machine It has reached the world's advanced level, and has been granted 1 invention patent and 4 utility model patents. It has won the “Spring Yan Award†from China CNC Machine Tool Exhibition; the successful development of YW7232CNC high-efficiency and high-precision gear grinding machine has mastered the advanced technology and improved the world's high-end equipment manufacturing field. China's high-end equipment manufacturing level is of great significance.
Chongqing Machine Tool Group, the user of this batch of high-efficiency precision gear grinding machine, Chongqing Qingshan Industry, is a state-owned large-scale industrial enterprise owned by China Ordnance Equipment Group Co., Ltd. It is the largest professional transmission manufacturer in China and the world's largest manufacturer of miniature automobile transmissions. one.
The delivery of YW7232CNC high-efficiency precision gear grinding machine can accelerate the upgrading of gear processing equipment in China's automobile, aerospace and other industries, and enhance the technological innovation capability and international competitiveness of China's tooth manufacturing industry, which is a milestone.
