In order to improve the processing efficiency and accuracy of complex special-shaped products, process engineers have been seeking more efficient and precise processing methods. The emergence of turn-mill composite processing equipment provides an effective solution to improve the processing accuracy and efficiency of aerospace parts.
Processing efficiency and accuracy are the eternal goals pursued 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 the requirements for processing speed, efficiency and accuracy. Against this background, composite processing technology came into being. Generally speaking, composite processing refers to a general term for processing technologies that can complete different procedures or different processing methods on one processing equipment. Composite processing technology is mainly divided into two different types: one is the combination of different processing methods based on energy or motion mode; the other is based on the principle of process concentration, dominated by mechanical processing technology. Turn-mill composite processing is one of the fastest developing processing methods in this field in recent years.
Aviation product parts are characterized by multi-variety and small-batch production, complicated technological processes, and extensive adoption of integral thin-wall structures and difficult-to-machine materials. Therefore, there are common bottlenecks in the manufacturing process such as long manufacturing cycle, large material removal volume, low processing efficiency and serious processing deformation. In order to improve the processing efficiency and accuracy of complex aviation products, process engineers have been seeking more efficient and precise processing methods. The emergence of turn-mill composite processing equipment provides an effective solution to improve the processing accuracy and efficiency of aviation parts.
The prominent advantages of turn-mill composite processing are mainly reflected in the following aspects:
(1) Shorten the product manufacturing process chain and improve production efficiency. It can be equipped with a variety of special tools. The new tool arrangement reduces tool change time and improves processing efficiency. Turn-mill composite processing can complete all or most of the processing procedures in one clamping, thus greatly shortening the product manufacturing process chain. On the one hand, it reduces the auxiliary production time caused by clamping changes, and also cuts down the manufacturing cycle and waiting time of fixtures, which can significantly improve production efficiency.
(2) Reduce clamping times and improve processing accuracy. The reduction of clamping times avoids error accumulation caused by the conversion of positioning benchmarks. At the same time, most turn-mill composite processing equipment has the function of on-line detection, which can realize in-position detection and precision control of key data in the manufacturing process, so as to improve product processing accuracy. The high-strength integrated bed design enhances the gravity processing capacity for difficult-to-cut materials. The machine tool is equipped with an automatic feeding device, which can realize automatic feeding for continuous production and basically achieve assembly line operation of a single machine tool.
(3) Reduce floor space and lower production costs. The compact and elegant appearance design optimizes space utilization and facilitates maintenance and repair to maximize customer satisfaction. Although the unit price of turn-mill composite processing equipment is relatively high, the shortening of the manufacturing process chain, the reduction of required production equipment, as well as fewer fixtures, smaller workshop floor area and lower equipment maintenance costs can effectively reduce the overall fixed asset investment, production operation and management costs.
