Development of precision precision CNC grinding machine

The “Shaft-type Precision Composite CNC Grinding Machine” project is a national science and technology major project undertaken by Shanghai Machine Tool Works Co., Ltd. and passed the acceptance test at the end of 2011. The result is H405-BE large-scale compound CNC grinding machine, which is the Shanghai machine tool for Shenyang Liming. Developed by Aero Engine (Group) Co., Ltd., mainly used to process core parts of aero engines. Through the two-day production of the user, the composite CNC grinding machine has won high praise from users for its good precision and performance. It not only shows the research and development strength of Shanghai machine tools, but also lays a foundation for the industrialization of the “sleeve-type precision composite CNC grinding machine” project.

As a result of major special projects, H405-BE large-scale composite CNC grinding machine adopts a variety of new technologies, new structures and new processes, and replaces the traditional universal cylindrical grinding machine technology with patented new technology. Not long ago, Huang Haitao, deputy general manager of Shanghai Machine Tool, led the relevant personnel to the Shenyang Axis Aero Engine (Group) Co., Ltd., to investigate the use of composite CNC grinding machines. In the investigation, the company equipment, the manufacturer of the reel factory, the maintenance personnel and the machine tool operator are very satisfied with the performance and quality of the machine tool, especially in the processing of high-temperature alloy materials, the grinding precision has far exceeded 0.005mm. The design accuracy requirements reflect the high-precision characteristics of the new generation of composite CNC grinding machines.

In the investigation, Shanghai Machine Tool also recommended the special grinding wheel and grinding of the “Major machine tool for ultra-high-speed precision cylindrical grinding machine”, which is the result of the major special project of Shanghai Machine Tool, in view of the particularity of materials processed by the shaft drilling processing plant of Shenyang Liming Aero Engine Company. Process to help it further improve grinding efficiency and precision. In addition, Shanghai Machine Tool Technology Center has updated the secondary development software of CNC composite grinding machine several times. The company will send professional technicians to provide value-added services for Dawn Aero Engine Company and provide technical training for machine tool operators to make them more correct. It is more convenient to use this large composite CNC grinding machine to maximize its accuracy and efficiency.
