Advantages of turning and milling compound machining

Brief introduction

In order to improve the processing efficiency and precision of complex special-shaped products, technicians have been seeking efficient and precise processing methods. The emergence of turning and milling composite processing equipment provides an effective solution for improving the machining accuracy and efficiency of aerospace parts.

Machining efficiency and precision are the eternal goals in the field of metal processing. With the continuous development of numerical control technology, computer technology, machine tool technology and processing technology, traditional processing concepts can no longer meet people's requirements for processing speed, efficiency and precision. In this context, composite processing technology came into being. Generally speaking, compound processing refers to the processing technology that can complete different processes or different processing methods on the same processing equipment. Composite processing technology is mainly manifested in two different types, one is a combination of different processing methods based on energy or motion; the other is a combination based on the principle of process concentration and mainly mechanical processing technology. Turn-milling machining is one of the fastest developing methods in this field in recent years.

Aviation product parts have the characteristics of many varieties, small batches, complex processes, overall thin-walled structure and wide application of difficult-to-machine materials. Therefore, there are many bottlenecks in the manufacturing process, such as long manufacturing cycle, large material removal, low processing efficiency, and serious processing deformation. In order to improve the machining efficiency and precision of complex aerospace products, technicians are always looking for more efficient and precise machining methods. The emergence of turning and milling composite processing equipment provides an effective solution for improving the machining accuracy and efficiency of aerospace parts.

Significance

Turn-milling is an advanced cutting method, which utilizes the combined motion of milling cutter rotation and workpiece rotation to realize the cutting of the workpiece, so that the workpiece can be improved in shape accuracy, position accuracy, and machined surface integrity. Turn-milling compound machining is not a simple turning-milling compound machining on the machine tool, but a new cutting theory and cutting technology formed under the condition of the great development of CNC technology.

Advantage

Compared with traditional CNC machining technology, the outstanding advantages of turning and milling compound machining are mainly reflected in the following aspects:

(1) Shorten the manufacturing process chain and improve production efficiency. A variety of special tools can be installed, and new tool layouts can reduce tool change time and improve processing efficiency. Turn-milling combined machining can complete all or most of the machining processes in one clamping, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistance time caused by the replacement of the jig is reduced, and on the other hand, the manufacturing cycle and waiting time of the jig are also reduced, which can significantly improve the production efficiency.

(2) Reduce the number of clamping and improve the machining accuracy. The reduction in loading times avoids the accumulation of errors due to positioning datum transitions. At the same time, most of the turning-milling composite processing equipment has the online detection function, which can realize the in-situ detection and precise control of key data in the manufacturing process, thereby improving the processing accuracy of the product; the high-strength integrated bed design improves the gravity processing ability of difficult-to-cut materials ; This machine is equipped with an automatic feeding device, which can realize continuous automatic feeding and basically realize the assembly line operation of a single machine tool.

(3) Reduce floor space and production costs. The compact and beautiful appearance design improves the space utilization, makes maintenance and repairs more convenient, and meets customer needs. Although the unit price of turn-milling composite processing equipment is higher, due to the shortening of the manufacturing process chain and the reduction of equipment required for products, as well as the reduction of the number of fixtures, the total fixed assets, workshop area and equipment maintenance costs can be effectively reduced.
