In order to improve the processing efficiency and accuracy of complex special-shaped products, technicians have been looking for efficient and precise processing methods. The emergence of turn-mill compound processing equipment provides an effective solution for improving the machining accuracy and efficiency of aerospace parts.
CNC 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, the traditional processing concept can no longer meet people's requirements for processing speed, efficiency and accuracy. In this context, composite processing technology came into being. Generally speaking, composite 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 mode; The other is based on the principle of process centralization, based on the combination of machining technology. Turn-milling compound machining is one of the fastest-growing methods in this field in recent years.
Aviation product parts have the characteristics of many varieties, small batches, complex processes, overall thin-walled structures and a wide range of applications of difficult-to-process materials. Therefore, there are many bottlenecks in the manufacturing process, such as long manufacturing cycle, large amount of material removal, low processing efficiency, and serious processing deformation. In order to improve the processing efficiency and precision of complex aerospace products, technicians are always looking for more efficient and accurate processing methods. The emergence of turn-milling compound processing equipment provides an effective solution for improving the machining accuracy and efficiency of aviation parts.
Significance
Turning and milling is an advanced cutting method, which uses the combined movement of milling cutter rotation and workpiece rotation to realize the cutting of the workpiece, so that the workpiece can be processed in shape accuracy, position accuracy, machining surface integrity, etc. Turn-milling compound machining is not simply a turning and milling compound processing on a machine tool, but a new cutting theory and cutting technology formed under the condition of the great development of numerical control technology.
Advantage
Compared with the traditional CNC machining technology, the outstanding advantages of turn-milling compound machining are mainly manifested 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 machining efficiency. Mill-turn machining can complete all or most of the machining operations in a single clamping, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production auxiliary time brought about by the fixture replacement is reduced, and on the other hand, the manufacturing cycle and waiting time of the fixture are also reduced, which can significantly improve the production efficiency.
(2) Reduce the number of clamping times and improve the processing accuracy. The reduction in the number of loads avoids the accumulation of errors due to the conversion of the positioning datum. At the same time, most of the turning-milling compound processing equipment has an online detection function, which can realize the in-situ detection and precise control of key data in the manufacturing process, so as to improve the processing accuracy of the product; High-strength integrated bed design to improve the gravity processing ability of difficult-to-cut materials; This machine is equipped with an automatic feeding device, which can realize continuous automatic feeding, which is basically realized. Single-machine machine assembly line operation.
(3) Reduce floor space and production costs. The compact and beautiful shape design improves the use of space, makes maintenance and repair more convenient, and meets customer needs. Although the unit price of turn-mill compound processing equipment is higher, due to the shortening of the manufacturing process chain, the reduction of equipment required for products, and the reduction of the number of fixtures, it can effectively reduce the total amount of fixed assets, workshop area and equipment maintenance costs. Investment, production, operating and management costs.
