Numerical control technology and equipment are the enabling technology and the most basic equipment for the development of emerging high-tech industries and cutting-edge industries. The information industry, biological industry, aviation, aerospace and other national defense industries all over the world widely use numerical control technology to improve manufacturing capabilities and levels, and improve market adaptability and competitiveness. Industrially developed countries also list numerical control technology and numerical control equipment as national strategic materials, not only vigorously develop their own numerical control technology and its industry, but also implement blockade and restriction policies on my country in terms of "high-tech" key numerical control technology and equipment. In short, vigorously developing advanced manufacturing technology with numerical control technology as the core has become an important way for all developed countries in the world to accelerate economic development and improve comprehensive national strength and national status.

The heat dissipation of electronic products is inseparable from the heat sink. The heat sink includes the base plate and the cooling teeth formed on the top of the base plate. The subsequent processing of the heat sink includes rough grinding, fine grinding, rough milling, fine milling, and drilling. Use the single-axis CNC machine tool to process the radiator. Before processing, first place the substrate of the radiator to be processed in the vacuum port of the vacuum suction cup, and then evacuate the vacuum to install the radiator, and then install it on the single-axis CNC machine tool. The forming tool on the machine tool processes the radiator. After one process of processing all the radiators on the vacuum chuck, the single-axis CNC machine tool is replaced with another tool to continue processing all the radiators on the vacuum chuck. The operation of all processes on the radiator can be completed, and this operation mode has the defect of low processing efficiency. In addition, Z-axis single-axis machining of single-axis CNC machine tools has low efficiency; low spindle speed and slow feed; single-axis single-knife multi-process processing has slow speed, which further leads to slow production speed of radiators and is not suitable for mass production.
