Machining of CNC turning and milling composite parts

In order to improve the machining efficiency and accuracy of complex special-shaped products, technologists have been seeking for efficient and precise machining methods. The appearance of turn milling compound machining equipment provides an effective solution for improving the machining accuracy and efficiency of aerospace parts.

Machining efficiency and precision is the eternal goal 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 not meet the requirements of processing speed, efficiency and accuracy. In this context, composite machining technology came into being. Generally speaking, composite processing refers to the general term of processing technology that can complete different processes or different process methods on a single processing equipment. There are two different types of compound processing technology, one is the combination of different processing methods based on energy or motion mode; the other is the combination based on the principle of process concentration and mechanical processing technology. Turning milling compound processing is one of the processing methods that have developed rapidly in recent years.

Aviation product parts are characterized by many varieties, small batch, complex process, and widely used as a whole thin-walled structure and 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 machining efficiency and accuracy of aviation complex products, technologists have been seeking more efficient and precise machining methods. The appearance of turn milling compound machining equipment provides an effective solution for improving the machining accuracy and efficiency of aviation parts.

Meaning

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 workpiece and make the workpiece meet the requirements in many aspects such as shape accuracy, position accuracy, machined surface integrity, etc. Turning milling compound machining is not only a combination of turning and milling methods into a machine tool, but also a new cutting theory and technology under the condition of great development of CNC technology.

advantage

Compared with the conventional NC machining process, the outstanding advantages of turning milling composite machining mainly lie in the following aspects:

(1) Shorten product manufacturing process chain and improve production efficiency. A variety of special cutters can be installed, new cutter arrangement can reduce tool change time, improve processing efficiency, turn milling compound processing can achieve one-time clamping to complete all or most of the processing procedures, thus greatly shortening the product manufacturing process chain. On the one hand, it can reduce the auxiliary production time caused by the change of fixture, and reduce the manufacturing cycle and waiting time of fixture, which can significantly improve the production efficiency.

(2) Reduce clamping times and improve machining accuracy. The reduction of the loading times avoids the error accumulation caused by the transformation of the positioning datum. At the same time, most of the turning milling complex processing equipment has the function of on-line detection, which can realize the on-site detection and precision control of key data in the manufacturing process, so as to improve the processing accuracy of products; the high-strength integrated bed design improves the gravity processing power of difficult cutting materials; the machine is equipped with an automatic feeding device, which can realize the automatic feeding for continuous, basically realized Assembly line operation of single machine tool.

(3) Reduce floor space and production cost. Compact and beautiful appearance design improves the way of space utilization, Maintenance and repair are more convenient for customers to get great satisfaction; although the price of single turning milling compound processing equipment is relatively high, due to the shortening of manufacturing process chain and the reduction of equipment required for products, as well as the reduction of fixture quantity, workshop floor area and equipment maintenance cost, it can effectively reduce the investment, production operation and management cost of total fixed assets.
