CNC turning and milling combined processing has a wide range and can cover multiple fields and processing needs. Here is some detailed description of its processing scope:

1. Processing type: CNC turning and milling compound processing can realize a variety of processing methods such as rough machining and finishing. Rough machining is usually used to process larger workpieces. Different machining methods are achieved through multiple tool changes. The requirements for the accuracy and surface quality of the workpiece are relatively low, but it can greatly shorten the entire machining cycle and improve machining efficiency. Finishing is mainly used to process workpieces with complex graphics and shapes. It has high requirements on the size and surface quality of the workpiece and can achieve high-precision and high-quality processing.

2. Processing materials: CNC turning and milling composite processing is suitable for various materials, including steel, gray iron, non-ferrous metals, etc., and can achieve cutting rigidity.

3. Processing parts: CNC turning and milling composite processing is especially suitable for the processing of short shaft and disc parts, as well as the cylindrical surface, arc surface, conical surface, etc. of the rotation body in the automobile, motorcycle, aerospace, military, petroleum and other industries. End faces, grooving, various metric and inch threads, and square milling are automatically processed in batches, efficiently, and with high precision. In addition, it also supports the processing of various parts such as columns, cones, arcs, spheres, threads, and grooving. After equipped with a special chuck, it can also process tees, crosses, elbows and plumbing pipe joints, including small valve bodies.

4. Processing efficiency: The design of the turning-milling compound machine tool enables multiple tasks to be completed in one clamping, which greatly improves the processing efficiency and processing accuracy. Through composite machining, the transfer and repositioning of workpieces between different machine tools can be reduced, thereby further shortening the machining cycle.

To sum up, CNC turning and milling composite processing has a very wide range and can meet various complex and high-precision processing needs. However, the specific processing scope needs to be determined based on factors such as the model, specification and performance of the machine tool. Therefore, when choosing CNC turning and milling composite processing, it is necessary to evaluate and select based on actual needs and processing conditions.
