Aluminum alloy is the most widely used non-ferrous metal material in the industry, and it is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, chemical industry, household appliances and daily necessities. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy precision parts is increasing, so that the CNC machining technology of aluminum alloy has also been studied more and more deeply.
Pure aluminum has low density, low melting point, high plasticity, easy processing, and can be made into various profiles and plates. Good corrosion resistance. Aluminum alloy is obtained by adding other metal elements to metal aluminum to obtain a metal alloy, such as silicon, iron, copper, aluminum, etc. The aluminum alloy obtained by adding other metals has the characteristics of low density, high strength and corrosion resistance. The characteristics such as strength and strength make aluminum alloys widely used in the processing and manufacturing of various parts, and aluminum alloy parts are widely used in industry and life.
The wide application of aluminum alloys promotes the development of CNC machining technology for aluminum alloys. At the same time, the development of CNC machining technology expands the application field of aluminum alloys. Therefore, CNC machining technology for aluminum alloys has become a research hotspot.
Machining of aluminum alloy parts, also known as CNC machining, automatic lathe machining, CNC lathe machining, etc., is characterized by machining mold parts with general machine tools such as turning, milling, creating, drilling, grinding, etc., and then performing necessary fitter repairs. It is difficult to ensure high machining accuracy with ordinary machine tools for mold parts with high precision requirements, so precision machine tools are required for processing; It is more automated and reduces the workload of fitters. It is necessary to use CNC machine tools (such as three-coordinate CNC milling machines, machining centers, CNC grinding machines and other equipment) to process mold parts.
CNC cutting is a processing method that makes cutting more rational, and it is also a common process of aluminum alloy precision machining. It adopts end mills with multi-directional cutting functions, helical cutting interpolation and contour cutting interpolation. A small number of holes are machined with as few tools as possible. The unique advantage of CNC machining of aluminum alloy precision parts is that the ball end mill combined with the helical interpolation method can continuously process the taper hole; the ball end mill and the helical interpolation drill can be used for boring and chamfering. Machining; end mills combined with equal-height plunge interpolation can perform semi-finishing and precision parts processing on holes; end mills for thread processing combined with helical interpolation can process various threaded holes.With the development of material science, the advancement of manufacturing technology, and the wide application of aluminum alloys, the requirements for the processing quality of aluminum alloy precision parts are getting higher and higher. The CNC machining technology of aluminum alloy precision parts is more and more widely used. People’s requirements for CNC machining quality of aluminum alloy precision parts are also getting higher and higher. Therefore, further research and development and improvement of CNC machining technology and equipment for aluminum alloy precision parts have become the top priority and the direction of efforts in the aluminum alloy precision machining industry.
