CNC turning and milling combined processing is a processing method that combines the functions of a lathe and a milling machine. It can perform multiple processing operations such as turning and milling on the same machine tool. In auto parts processing, CNC turning and milling composite processing is widely used in the production of various parts, such as engine parts, steering system parts, chassis parts, etc.
CNC turning and milling combined processing has the following advantages:

1. High efficiency: CNC turning and milling compound machine tools can perform turning and milling operations on the same equipment, avoiding multiple clamping of workpieces and the time of changing machine tools, and improving processing efficiency.
2. High precision: CNC turning and milling compound machine tools are equipped with advanced CNC systems, which can achieve high-precision processing and ensure the size and surface quality requirements of the processed parts.
3. Strong flexibility: CNC turning and milling compound machine tools can perform different processing operations according to actual needs, such as turning, milling, drilling, tapping, etc., and have strong processing capabilities and flexibility.
4. Cost savings: The use of CNC turning and milling composite machine tools can reduce equipment investment and labor costs, while reducing errors and scrap rates during the processing process, and reducing production costs.

When CNC turning and milling composite processing auto parts, it is necessary to select appropriate tools, process parameters, tool paths, etc. according to specific parts requirements and processing technology. In addition, it is necessary to make full use of the functions of CNC machine tools and reasonably arrange the processing sequence and process flow to ensure processing quality and efficiency.
In short, CNC turning and milling combined processing is an efficient, high-precision and flexible processing method, and has wide application prospects in auto parts processing. Through reasonable selection and optimization of processing strategies, production efficiency can be improved, costs can be reduced, and the automotive industry's demand for high-quality parts can be met.
