What will the application of precision parts machining in the aviation industry be like? As follows!
With the rapid development of the aviation industry, the semi-finished products of industrial aluminum profiles put forward higher and higher requirements, especially for high-speed military and civilian aircraft require the use of more perfect semi-finished products, in order to make the structure of each component more reasonable, to ensure a lighter structural quality, strength and rigidity, while significantly reducing the number of components, reducing the cost of group paddle, jointing and maintenance, etc.. Ensure perfect and beautiful surface (good sealing, no seams, no deformation, etc.).
(1) Large industrial aluminum profiles belong to the particularly important structural parts on the aircraft, requiring the profiles to have excellent mechanical properties. Therefore, aluminum profiles must be produced by customizing industrial aluminum alloy profiles using hard aluminum or super hard aluminum alloy to extrude.
(2) Since industrial aluminum profiles are used as structural parts of key parts of the aircraft, good overall performance and uniform organization are required, especially for the finished products and very strict requirements. And extrusion after quenching products in the coarse crystal ring defects is very difficult to avoid, but also the world's extrusion workers for decades with little success Minde aluminum 868 profile specific gravity table one of the research topics.
(3) for the cross flower beam and comb joint plate and other aluminum profiles, on the one hand, its large cross-sectional area, often makes the extrusion deformation coefficient is relatively small, while on the other hand, its lateral and high to must withstand a large load, and thus require its lateral and high up to have a very high mechanical properties. This contradiction is often an important reason for the scrapping of aluminum profiles.
