At the beginning of CNC machine tools, aircraft parts with complex profiles were selected as processing objects, which was the key to solving the problem that ordinary processing methods were difficult to solve.
The biggest feature of CNC machining is to use punched tape (or tape) to control the machine tool for automatic machining. Because aircraft, rockets and engine parts have different characteristics: zero, large component size and complex profile of aircraft and rockets; zero engine, small component size and high precision. Therefore, the CNC machine tools used in aircraft, rocket manufacturing and engine manufacturing departments are different. In aircraft and rocket manufacturing, large-scale CNC milling machines with continuous control are mainly used, while in engine manufacturing, both continuous-controlled CNC machine tools and point-controlled CNC machine tools (such as CNC drilling machines, CNC boring machines, machining centers, etc.) are used. .
