CNC turn-mill machining is a composite machining that combines turning and milling on one CNC machine tool. Its benefits include:

1. Improve production efficiency: CNC turning and milling compound machine tools can complete various processing operations such as turning and milling on the same equipment, without transferring workpieces to different machine tools. This reduces workpiece clamping and changeover times, increases productivity and saves production time.
2. Improve machining accuracy: Since the CNC turning-milling machine tool has a high-precision positioning and control system, more accurate machining can be achieved. One-time clamping can complete the processing of multiple processes, reducing workpiece positioning errors and errors caused by repeated clamping, thereby improving processing accuracy.
3. Increased processing capacity: CNC turning and milling compound machine tools can perform a variety of different processing operations on one device, such as turning, milling, drilling, tapping, etc., with a wider range of processing capabilities. This makes it suitable for machining more complex workpieces and fulfilling various machining needs.
4. Reduce workpiece handling: Traditionally, machining operations such as turning and milling often need to be performed on different machine tools, resulting in multiple process changes and machining of workpieces. The CNC turning and milling compound machine tool can complete multiple processes at one time, which reduces the processing and handling of workpieces, and reduces labor costs and working hours.
5. Provide flexibility: CNC turning and milling compound machine tools have flexible CNC programming capabilities, which can be freely programmed and adjusted according to processing needs. This enables it to adapt to the processing requirements of different workpieces, providing higher production flexibility.

All in all, CNC turning and milling has the advantages of high efficiency, precision, multi-function and flexibility, which can improve production efficiency, reduce costs, and adapt to diverse processing needs.
