1) Shorten product manufacturing process chain and improve production efficiency. Turning and milling complex machining can realize the completion of all or most of the processing process at one time, thus greatly shortening the product manufacturing process chain. On the one hand, the production auxiliary time caused by the change of loading card is reduced, and the manufacturing cycle and waiting time of fixture and fixture are also reduced, which can significantly improve the production efficiency.

(2) Reduce the number of clamping, improve the machining accuracy. The reduction of card loading times avoids error accumulation caused by reference conversion. At the same time, most of the current turn-milling compound processing equipment has the function of online detection, which can realize the in-position detection and precision control of the key data in the manufacturing process, so as to improve the machining accuracy of products.

(3) Reduce floor area and production cost. Although the price per unit of turn-milling compound processing equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of equipment required for the product, as well as the reduction of the number of fixtures, workshop floor space and equipment maintenance costs, it can effectively reduce the overall fixed asset investment, production operation and management costs.
