In this era when hardware processing is prevalent, mechanical equipment should improve the processing level, not to mention hardware precision parts processing, but also in the scope of the effect. With the expansion of the hardware processing market, the speed is getting faster and faster. Now there are many mechanical equipments developed, but the processing strength has not yet reached the ideal, so it is necessary to improve the processing technology, there are still some reasons, now let's take a look at how to improve the processing technology of aluminum alloy and hardware precision parts! Aluminum Alloy is the most widely used non-ferrous metal material in the industry and is widely used in aviation, aerospace, automobile, machinery manufacturing, shipping, chemical industry, household appliances and daily necessities. With the rapid development of science and technology and industrial economy in recent years, the demand for precision parts of aluminum alloy is increasing day by day, making the hardware processing technology of aluminum alloy more and more in-depth research. Pure aluminum has low density, low melting point, high plasticity and easy processing, and can be made into various profiles and plates. Good corrosion resistance. The aluminum alloy is obtained by adding other metal elements to the metal aluminum, such as silicon, iron, copper, aluminum, etc. The aluminum alloy obtained by adding other metals has a small density, high strength, corrosion resistance and other characteristics, its light weight and strength make aluminum alloy widely used in the processing and manufacture of various parts, aluminum alloy parts are widely used in industry and life. The wide application of aluminum alloy has promoted the development of aluminum alloy hardware processing technology. At the same time, the development of hardware processing technology has expanded the application field of aluminum alloy. Therefore, the hardware processing technology of aluminum alloy has become a research hotspot. Mechanical processing of aluminum alloy parts, also known as hardware processing, automatic lathe processing, CNC lathe processing, etc. , is characterized by using general machine tools such as car, milling, planing, drilling, grinding, etc, then carry out the necessary fitter repair and assembly into various molds; The mold parts with high precision requirements are difficult to guarantee high machining accuracy only by ordinary machine tools, so it is necessary to use precision machine tools for processing; In order to make mold parts, especially convex molds with complex shapes, the processing of concave model holes and cavities more automated and reduce the workload of fitters, numerical control machine tools ( Such as three-coordinate CNC milling machine, machining center, CNC Grinding Machine, etc)Process mold parts. Hardware Processing and cutting is a processing method that makes cutting processing more rational, and it is also a common process for precision processing of aluminum alloy, using end milling cutter with multi-direction cutting function, spiral cutting interpolation and equal high cutting interpolation, it uses as few tools as possible to process a small number of holes. The unique advantage of metal processing of aluminum alloy precision parts lies in the continuous processing of taper holes by ball end milling cutter combined with spiral interpolation method; Boring and inverted edge processing can be carried out by using ball head end milling cutter and spiral interpolation drill bit; The end milling cutter can perform semi-finishing and precision parts processing on the hole with the same high cut-in interpolation; The end milling cutter used for thread processing can perform various threaded hole processing with spiral interpolation method.
