CNC turning and milling compound, also known as CNC turning and milling compound, is a processing method that integrates the functions and characteristics of CNC lathe and CNC milling machine on one machine tool to realize turning and milling.
CNC turning and milling compound machine tools have the functions of CNC lathes and CNC milling machines, which can perform rotary cutting and straight or curved cutting, and complete these processing operations on the same machine tool. It can realize turning, milling, boring, drilling, tapping and other processing operations on the same workpiece, realizing the diversification and high efficiency of processing.
CNC turning and milling machine tools are usually equipped with a CNC system, and the operator can use the CNC programming language (such as G code, M code) to guide and control the machining process. By setting the tool path and cutting parameters reasonably, the processing tasks of complex shapes can be completed, and parts with high precision and high surface quality can be obtained.
Compared with traditional CNC lathes and CNC milling machines that operate separately, CNC turning-milling machine tools have the following advantages:

1. Improve production efficiency: CNC turning and milling compound machine tools can complete multiple processing operations on the same machine tool, avoiding multiple clamping and transfer of workpieces, thereby improving production efficiency.
2. Reduce part deformation: Since multiple clamping of the workpiece is avoided, the CNC turning and milling compound machine tool can reduce the deformation of parts caused by inaccurate clamping and improve the machining accuracy.
3. Save floor space: CNC turning and milling compound machine tool combines the functions of lathe and milling machine into one, which can save the floor space of the workshop and improve the flexibility of production layout.
4. Shorten the delivery cycle: multiple processing operations can be completed through one clamping, and the CNC turning and milling compound machine tool can shorten the processing cycle of parts and speed up delivery.

It should be noted that CNC turning and milling composite machining requires high rigidity, stability and precision of the machine tool, and the operator needs to have corresponding programming and operation skills. Therefore, when selecting a CNC turning-milling machine tool, it is necessary to fully consider the processing needs, ensure that the performance and technical indicators of the machine tool meet the requirements, and provide training and technical support according to the actual situation.
