Aerospace reinforced threaded special thread rolling wheel (3)

(3) Strictly control the rolling process, adopt the correct rolling method and use equipment with high rigidity and high precision, otherwise the surface of the thread will have wrinkles, creases, scratches, cracks and breaks, and the life of the rolling tool is also low. In addition to the sharp decrease in the life of the rolling tool, the workpiece thread after rolling is sensitive to stress concentration and will cause premature fatigue damage to the workpiece thread.

The development direction of the rolling wheel

As the only specialized enterprise in the research and production of thread tools in China's aviation industry, Shaanxi Hongfeng has long been committed to the R&D, manufacturing, testing and testing of military thread measuring tools. For the production of titanium alloys and high-temperature alloys for the production of titanium alloys and high-temperature alloys, MJ has strengthened the experience of the externally threaded rolling wheels, and has strict production, processing and testing processes to ensure the connection of the threaded workpieces of aerospace enterprises to the reinforced thread. demand. At the same time, it utilizes the advantages of enterprise processing to solve the special rolling wheel for ring groove rivets used in aerospace enterprises for processing titanium alloys. In order to better serve aerospace companies, our company will continue to increase technological innovation, because only the development and design of tools that are difficult to process materials can become the preferred tool supplier for modern aerospace manufacturers.

The rapid development of high-speed cutting technology in China is a breakthrough in the understanding of traditional cutting in the cutting principle. It is different from conventional cutting in the cutting mechanism, and has its own characteristics and scope of application. Among the tool materials used for ultra-high-speed cutting at home and abroad, titanium alloy processing is mainly used for high-performance high-speed steel, powder high-speed steel, YG-type hard alloy, polycrystalline diamond PCD and cubic boron nitride.

The use of high-speed cutting technology and tool materials for the machining of titanium alloy external threads should seek the best match between the tool and the titanium alloy from many factors such as technology, machine tool support and auxiliary unit manufacturing technology, processing and testing technology. Solving the problem of processing titanium alloy not only ensures the processing quality but also greatly improves the productivity, and has a good development prospect. The processing of ultra-high-speed cutting technology for difficult-to-machine materials is gradually maturing, but how to further improve the rolling processing technology of ultra-high-speed cutting titanium alloy remains to be further studied.
