In order to improve the processing efficiency and processing accuracy of complex special-shaped products, craftsmen have been seeking more efficient and precise processing methods. The emergence of cnc hard turning provides an effective solution to improve the machining accuracy and efficiency of aerospace parts.
Processing efficiency and precision 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 people's requirements for processing speed, efficiency and precision. In this context, composite processing technology came into being. Generally speaking, composite processing refers to the general term for processing technologies that can complete different processes or different process methods on one processing equipment. Composite processing technology is mainly manifested in two different types, one is the composite of different processing methods based on energy or movement mode; the other is based on the principle of process concentration and mainly based on mechanical processing technology. Turn-milling combined machining is one of the fastest-growing machining methods in this field in recent years.
Aviation product parts are characterized by multi-variety and small batches, complicated process, and the overall thin-walled structure and difficult-to-machine materials are widely used. Therefore, long manufacturing cycles, large material removal, low processing efficiency, and serious processing deformation are common in the manufacturing process. bottleneck. In order to improve the processing efficiency and processing accuracy of aviation complex products, craftsmen have been seeking more efficient and precise processing methods. The emergence of turning-milling compound processing equipment provides an effective solution for improving the machining accuracy and efficiency of aviation parts.
