Compared with conventional CNC machining processes, CNC turning-milling compound machining boasts prominent advantages, mainly reflected in the following aspects:​

(1) Shortening the product manufacturing process chain and improving production efficiency. As introduced by CNC turning-milling compound machining manufacturers, this technology allows the installation of various special cutting tools and adopts a new tool arrangement, which reduces tool change time and enhances processing efficiency. Moreover, turning-milling compound machining can realize full or most processing procedures with a single clamping, thereby greatly shortening the product manufacturing process chain. On one hand, this reduces the auxiliary production time caused by clamping changes; on the other hand, it also shortens the manufacturing cycle and waiting time of tooling fixtures, which can significantly improve production efficiency.​

(2) Reducing the number of clamping times and improving processing accuracy. Fewer clamping operations avoid the error accumulation resulting from the conversion of positioning datums. According to the analysis of CNC turning-milling compound machining manufacturers, most of the current turning-milling compound machining equipment is equipped with on-line detection functions, which can realize in-situ detection of key data in the manufacturing process and precision control, thus improving the processing accuracy of products. In addition, the high-strength integrated bed design enhances the gravity processing capacity for difficult-to-cut materials. The machine tool is also equipped with an automatic feeding device, which can realize automatic loading for continuous operation and basically achieve assembly line work on a single machine tool.​

(3) Reducing floor space and lowering production costs. As analyzed by CNC turning-milling compound machining manufacturers, the compact and aesthetic appearance design optimizes the space utilization method and makes maintenance more convenient, maximizing customer satisfaction. Although the unit price of turning-milling compound machining equipment is relatively high, the shortened manufacturing process chain, reduced number of equipment required for products, as well as the decrease in the quantity of tooling fixtures, workshop floor space and equipment maintenance costs, can effectively reduce the overall investment in fixed assets and the costs of production operation and management.
