At present, the five-axis CNC machine tool system is the only way to solve the processing problems of large diesel engine impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, and crankshafts.

A CNC machine tool refers to a machine tool that can be processed automatically through pre-edited precise instructions. At present, most of the CNC machine tools are computer numerical control machine tools, and the computer plays the role of comprehensive control.

In modern computer numerical control systems, the design of workpieces is highly dependent on computer-aided design (CAD) and computer-aided manufacturing (CAM) software.

Computer-aided manufacturing software analyzes the design model and calculates the motion instructions during processing. The movement instructions and other auxiliary instructions used in the machining process are converted into the format read by the numerical control system through the post processor, and then the files generated by the post processor are loaded onto the computer numerical control machine tool for workpiece processing.

After the program instructions are input to the numerical control system, the computer performs data compilation and calculation. Through the displacement control system, the data is transmitted to the driver to drive the motor, and the designed parts are cut.

The five-axis machining center has the characteristics of high efficiency and high precision. The five-axis linkage machining center can use a workpiece fixture to complete pentahedral machining. If equipped with a five-axis linkage high-end CNC system, complex spatial surfaces can also be processed with high precision, which is more suitable for the processing of modern molds such as automobile parts and aircraft structural parts.

Domestic CNC machine tools are mainly low-end products, and high-end CNC machine tools mainly rely on imports. The consumption of imported domestic machine tools still accounts for about one-third of domestic machine tool consumption. High-end CNC machine tools lag far behind the international advanced technology in terms of accuracy and speed, and rely more on imports. According to relevant industry reports, the import rate of high-end CNC products is 80%.

Friends who love the military may know the famous Toshiba incident. At the end of the last century, Toshiba of Japan sold several five-axis CNC milling machines to the former Soviet Union. As a result, the former Soviet Union used them to build the propellers of submarines, so that the sonar of American spy ships could not hear the sound of submarines. Toshiba of the United States violated the strategic material embargo policy and imposed penalties on Toshiba. Therefore, high-end CNC machine tools are particularly important to our country.
