The five-axis linkage CNC machine tool is a high-tech, high-precision machine tool specially used for processing complex curved surfaces. This machine tool system is useful for a country’s aviation, aerospace, military, scientific research, precision equipment, high-precision medical equipment, etc. The industry has a decisive influence.
At present, the five-axis linkage CNC machine tool system is the only means to solve the processing of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, and so on.
CNC machine tools refer to machine tools that can be processed automatically through precise instructions edited in advance. At present, most CNC machine tools are computer numerical control machine tools, and the computer plays the role of integrated control.
In modern computer numerical control systems, the design of workpieces is highly dependent on software such as computer-aided design (CAD) and computer-aided manufacturing (CAM).
Computer-aided manufacturing software analyzes the design model and calculates the movement instructions during processing. The post-processor converts the movement instructions and other auxiliary instructions that need to be used during the processing into a format that can be read by the numerical control system, and then the post-processor The generated files are loaded into the computer numerical control machine tool for workpiece processing.
After inputting the program instruction into the numerical control system, it is compiled and calculated by the computer, and the data is transmitted to the driver through the displacement control system to drive the motor to cut and process the designed part.
The five-axis machining center has the characteristics of high efficiency and high precision, and the workpiece can be processed in a pentahedron in one clamping. If equipped with a five-axis linkage high-end numerical control system, it can also perform high-precision processing of complex spatial surfaces, and is more suitable for processing modern molds such as auto parts and aircraft structural parts.
Domestic CNC machine tools are also mainly low-end products, high-end CNC machine tools mainly rely on imports, and imports still account for about one-third of the entire domestic machine tool consumption. High-end CNC machine tools are far behind the international cutting-edge technology in terms of accuracy and speed, and are more dependent on imports. According to relevant industry reports, the import rate of high-end CNC products reaches 80%.
