Compared with conventional CNC machining technology, CNC turning-milling composite machining has outstanding advantages mainly in the following aspects.

(1) CNC turning and milling combined processing shortens the product manufacturing process chain and improves production efficiency. Turning and milling combined processing can complete all or most of the processing procedures at one time, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistance time caused by the change of the installation card is reduced, and the manufacturing cycle and waiting time of the tooling fixture are also reduced, which can significantly improve the production efficiency.

(2) Reduce the number of clamping and improve processing accuracy. The reduction in the number of card loading avoids the accumulation of errors due to the conversion of positioning benchmarks. At the same time, most of the current turning-milling composite processing equipment has the function of online detection, which can realize the in-position detection and precision control of key data in the manufacturing process, thereby improving the processing accuracy of the product.

(3) CNC turning and milling combined processing reduces floor space and reduces production costs. Although the price of a single unit of turning-milling combined processing equipment is relatively high, the overall fixed assets can be effectively reduced due to the shortening of the manufacturing process chain and the reduction of equipment required for products, as well as the reduction in the number of fixtures, workshop area and equipment maintenance costs. The cost of investment, production operation and management.
