Key points of aluminum alloy precision parts processing technology
Aluminum alloy is the most widely used non-ferrous metal material in industry, which is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, chemical industry, household appliances and daily necessities.
In recent years, with the rapid development of science and technology and industrial economy, the demand for aluminum alloy precision parts has been increasing, so that aluminum alloy CNC machining technology has also been more and more in-depth research.
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 a metal alloy 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 the characteristics of low density, high strength and corrosion resistance. Characteristics such as strength and strength make aluminum alloy 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 alloy has promoted the development of aluminum alloy CNC machining technology. At the same time, the development of CNC machining technology has expanded the application field of aluminum alloy. Therefore, aluminum alloy CNC machining technology has become a research hotspot.
Aluminum alloy parts processing, also known as CNC machining, automatic lathe processing, CNC lathe processing, etc., is characterized by the use of turning, milling, creating, drilling, grinding and other general machine tools to process mold parts, and then process. Carry out the necessary fitter repairs. For mold parts with high precision requirements, it is difficult to ensure high machining accuracy with ordinary machine tools, so precision machine tools are required for processing; It is more automated, reducing the workload of the assembler. CNC machine tools (such as three-coordinate CNC milling machines, machining centers, CNC grinding machines and other equipment) are required to process mold parts.
CNC cutting is a processing method that makes cutting more reasonable, and it is also a common process for precision machining of aluminum alloys. End mills with multi-directional cutting, helical cutting interpolation and contour cutting interpolation are used. Use as few tools as possible to make a small number of holes. The unique advantage of CNC machining aluminum alloy precision parts is that the ball nose end mill combined with the helical interpolation method can continuously machine the taper hole; Ball nose end mills and helical interpolation bits can be used for boring and chamfering. Processing; The end mill combines contour interpolation to perform semi-finishing and precision parts machining of holes; Threading end mills combined with helical interpolation can be used to machine a variety of threaded holes. With the development of material science, the progress of manufacturing technology and the wide application of aluminum alloy, the processing quality of aluminum alloy precision parts is required to be higher and higher. The application of CNC machining technology for aluminum alloy precision parts is becoming more and more extensive. 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 a top priority and direction of efforts in the aluminum alloy precision machining industry.
