brief introduction

In order to improve the processing efficiency and accuracy of complex special-shaped products, technicians have been seeking for efficient and precise processing methods. The emergence of Turning-Milling compound processing equipment provides an effective solution to improve the processing accuracy and efficiency of aerospace parts.

Machining efficiency and accuracy 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 not meet people's requirements for processing speed, efficiency and accuracy. In this context, composite processing technology emerged as the times require. Generally speaking, compound processing refers to the processing technology that can complete different processes or different process methods on a processing equipment. Compound processing technology is mainly manifested in two different types, 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 mainly based on mechanical processing technology. Turning-milling composite processing is one of the rapid development methods in this field in recent years.

Aeronautical product parts are characterized by many varieties, small batches, complex process, and wide use of integral thin-walled structure and difficult-to-process 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 processing efficiency and accuracy of aviation complex products, technicians have been seeking more efficient and precise processing methods. The emergence of Turning-Milling compound processing equipment provides an effective solution to improve the processing accuracy and efficiency of Aeronautical parts.

Meaning

Turn-milling is an advanced cutting method, which uses the combined motion of milling cutter rotation and workpiece rotation to realize the cutting of workpiece, so that the workpiece can meet the requirements of use in many aspects, such as shape accuracy, position accuracy, machined surface integrity, etc. Turning-milling composite machining is not simply a combination of turning and milling methods on a machine tool, but a new cutting theory and cutting technology under the condition of the great development of numerical control technology.

advantage

Compared with the conventional NC processing technology, the outstanding advantages of Turning-Milling composite processing are mainly manifested in the following aspects:

(1) To shorten the manufacturing process chain and improve production efficiency. It can install a variety of special tools, new tool layout, reduce tool changing time and improve processing efficiency. Turning-milling combined processing can achieve a single clamping to complete all or most of the processing procedures, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistant time caused by the change of fixture is reduced, on the other hand, the manufacturing cycle and waiting time of fixture are also reduced, which can significantly improve the production efficiency.

(2) Reduce clamping times and improve processing accuracy. The reduction of loading times avoids the accumulation of errors caused by the transformation of positioning datum. At the same time, Turning-Milling composite processing equipment mostly has the function of on-line detection, which can realize in-situ detection and precision control of key data in manufacturing process, thereby improving the processing accuracy of products; high-strength integrated bed design, which improves the gravity processing ability of difficult-to-cut materials; the machine is equipped with automatic feeding device, which can realize automatic feeding continuously and basically realized. Pipeline operation of a single machine tool.

(3) Reduce the area occupied and the production cost. Compact and beautiful shape design improves the way of space utilization and makes maintenance and repair more convenient to satisfy customers. Although the single price of Turning-Milling compound processing equipment is relatively high, the total fixed assets can be effectively reduced due to the shortening of manufacturing process chain and the reduction of equipment required for products, as well as the reduction of the number of fixtures, workshop area and equipment maintenance costs. Costs of investment, production, operation and management.
