Technology continues to improve, and the output value of machine tools ranks third in the world.
machine tools are the working machine of the equipment manufacturing industry, and are an important symbol of realizing the contact mode of equipment system: the modernization of manufacturing industry, representing a country's scientific level, innovation ability and comprehensive strength. Since the 30 years of reform and opening up, the output of CNC machine tools in China has increased nearly 200 times, and the ownership has increased about 500 times. In 2007, the output value of machine tools in China reached US $10.75 billion, a year-on-year increase of 44.14%, accounting for 14.7% of the total output value of machine tools in the world. This is the third consecutive year that the output value of machine tools in China ranks third in the world. In 2007, the numerical control rate of China's machine tool output increased from 9.12% in 2001 to 20.31%, and the numerical control rate of output value increased from 26.2% to 44%; The market share of domestic machine tools has increased from 39.3% to 56.3%, which is the first time that the market share of domestic machine tools has exceeded 50%. Secondly,
with the outstanding independent innovation ability of domestic machine tools and the continuous improvement of technical level, a large number of representative high-end and heavy-duty CNC machine tools have been born one after another. For example, Qizhong CNC Crankshaft Machining machine tool, Wuzhong seven axis five linkage turning and milling machining center, qierji super heavy floor boring machine, etc. In October, 2007, the world's first xnz2430 new large gantry type five axis machine tool with a service life less than the design life (see Figure) was launched in the Qi'er Machinery Co., Ltd. This machine tool is a major numerical control equipment of the National 863 plan undertaken by Qi'er Machinery Co., Ltd. automotive materials will enter the key technology development project in the aluminum period. The machine tool is a high-end product that replaces imports and provides strong technical and equipment support for the development of China's national defense industry
