Large-scale CNC machine tool processing line is a new DNC production mode

The CNC machining production line for large parts is a new DNC production mode. Its successful application provides direct data support for the reliability index of domestic CNC machine tools and domestic CNC systems. It has accumulated valuable experience for enterprises to form the most modern production organization management method, and has established the domestic use of domestic CNC system equipment and domestically produced equipment. The confidence of CNC machine tools has played a positive role in promoting the industrialization of CNC machine tools in China.

Hanchuan Machine Tool Co., Ltd., after undertaking the scientific and technological research project in 1997, on the basis of full investigation and repeated detailed reliability tests, entered the year 2000, the DNC network was fully operational, and the automatic programming technology was all up to standard. Through the network transmission, the CNC machining program generated by CAD/CAM has the function of production scheduling management. The single CNC machine tool calls the NC program function and the information distribution adopts the converter. According to the group technology, the workpiece is optimized and analyzed, and the process plan and implementation countermeasures are determined. The processing technology is scientific and reasonable, the processing precision is accurate, the quality is stable, the processing efficiency is doubled, and the processing cost is greatly reduced. The CNC machining production line of Hanchuan Machine Tool Co., Ltd. consists of 7 CNC machine tools and machining centers, including 2 large horizontal CNC milling machines, 1 vertical CNC milling machine, 1 horizontal machining center, 2 vertical conversion machining centers, and gantry type. One processing center. 5 sets of CNC equipment manufactured and manufactured by the company itself, and domestic CNC systems have also accounted for more than 50%. The production line can process large parts such as saddles, columns, boxes and special shapes of 60 kinds of leading products such as electric machine tools, CNC milling machines, machining centers, coordinate boring machines and horizontal boring machines. The annual output can reach 2,400 pieces. The output value is 10 million yuan.

The experts of the National Machinery Bureau Acceptance Group believe that the research and application of the company's DNC network technology has realized the CNC machining, control, management network, automation, flexibility, development of practical management software and communication interface programs of different CNC systems, its application The level has been in the leading position in the domestic industry. The processing scale of the DNC production line has already been based on industrialization. The successful development and application of this national key scientific and technological research project will greatly enhance the competitiveness of China's manufacturing industry and create a good development environment for promoting the domestic CNC machine tool industry.
