Recently, the CNC horizontal side broaching machine developed by Changer Equipment (stock code 833115) for precision broaching of aircraft engine turbine discs has been assembled and commissioned, and various performance indicators have met the design requirements. After trial cutting, the machining accuracy of the workpiece meets the requirements of the drawings. This equipment is the first high-performance broaching machine with independent intellectual property rights in China. It is customized for a well-known new three-board listed company in China.
The “Nineteenth National Congress” identified China's national strategic top 100 engineering projects, the first of which is aviation engines and gas turbines, and the high-speed CNC side broaching machine is one of the key processing equipment for its core components. In order to break the international monopoly and technical blockade, and achieve high-end equipment to replace imports, Changer has completed the research of the first generation of models after ten years of scientific research.
Liu Zhonghua, chief engineer of Changer Aviation Equipment R&D Center, said that in the future, Changer team will further work hard to develop high-speed CNC side broaching machine for turbine disk grooving, and strive to catch up with the advanced level of similar products in Germany within three years and help China. Big airplane dreams.
