When back to reference point fault occurs in the operation of CNC machine tools in Guangdong Machinery processing plant, it mainly occurs in the above aspects. According to the principle of back to reference point, we can check step by step in order to find the key point and use the correct method to eliminate the fault. On February 4, Wu Bolin, director general of China Machine Tool Industry Association, told China industry daily that the "guide for major projects of high-end CNC machine tools and basic manufacturing equipment" will be released in the middle of this month, which means that the last one of the 16 major national science and technology projects will be launched soon.
Previous research conducted by Guangdong Machinery processing plant shows that the four major industries of aerospace, shipbuilding, automobile and power generation equipment targeted by major machine tool projects present three characteristics: first, the industry develops rapidly, the output of automobile, shipbuilding and power generation equipment rises rapidly, and the aviation industry has a heavy processing task; Second, the industry has a good development prospect, and enterprises generally increase investment in technological transformation; Third, a large number of high-end CNC machine tools are needed for assembly. The above characteristics show that it is a rare opportunity for the development of China's high-end CNC machine tools, and it is time to start the major projects of CNC machine tools.
The special key tasks aim at the equipment required in four major fields
According to the survey of users in four major fields, Guangdong Machinery processing plant has focused on developing high-speed precision compound CNC metal cutting machine tools (18 kinds), Heavy CNC metal cutting machine tools (7 kinds), CNC special machining machine tools (4 kinds) and large-scale CNC forming and stamping equipment (11 kinds), These products basically cover the four major users' demand for high-end CNC machine tools in the next 10 to 15 years. They are urgently needed CNC equipment in the four major fields. These products are difficult to import from abroad or not to export to China. The projects listed in the key tasks can basically meet the development needs of the four major areas. The overall situation is as follows:
There are 7 Heavy CNC metal cutting machines listed in the special key tasks of Guangdong mechanical processing plant, including heavy vertical lathe, gantry lathe, etc? Roller grinder can meet the complex, efficient and complex processing requirements of super heavy and heavy parts for ships, power generation equipment and large aircraft.
There are 7 CNC lathe and machining center projects listed in the special key tasks, including high-speed precision lathe, machining center and compound machine tool, which can meet the needs of aerospace, shipbuilding, power generation equipment, automobile manufacturing and other industries for high-speed, precision and compound processing.
There are 9 CNC grinding machine projects listed in the special key tasks, including various CNC grinding machines, which can meet the needs of aviation, shipbuilding, power generation equipment, automobile manufacturing and other industries for high-speed, precision and compound grinding.
There are 2 gear processing projects listed in the special key tasks, among which the large gear hobbing machine and gear grinding machine can meet the requirements of large and precision gear processing such as large mining equipment, large marine gearbox and wind power equipment.
There are 2 electric machining machine projects listed in the special key tasks, including CNC wire cutting and forming machine, which can meet the needs of aviation, mold, home appliances and other industries for special processing.
There are 11 large-scale CNC forming equipment projects listed in the special key tasks, which can meet the needs of automobile, ship, power generation, home appliances and other industries for metal forming processing.
Experts from Guangdong mechanical processing plant who participated in the major special investigation of machine tools believe that with the development of the four major industries, in addition to the key tasks listed in the special project, a large number of different types and specifications of CNC machine tools and special machine tools are needed, such as various kinds of special equipment for digital control and special machine tools for large aircraft manufacturing "CNC blade root groove milling machine" and "CNC rotor groove milling machine" for large steam turbine and generator rotor processing, "CNC shaping gear milling machine" and "CNC shaping gear grinding machine" for wind power equipment processing, "super heavy deep space drilling machine" for large nuclear power pressure vessel processing, "breaking machine for connecting rod processing of key parts of automobile engine" and high-efficiency, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high- It is suggested that the rolling plan should be carried out to supplement the major CNC equipment projects urgently needed by the four industries
