Aluminum alloy is the most widely used non-ferrous metal material in industry. 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 this year As the demand for aluminum alloy precision parts is increasing, the CNC machining process 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, such as silicon, iron, copper, aluminum, etc. The aluminum alloy obtained by adding other metals has low density, high strength, corrosion resistance, etc. Features, its lightness 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 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-purpose machine tools such as turning, milling, planing, drilling, and grinding, and then performing necessary fitter repairs and assembly into each A kind of mold, mold parts with high precision requirements, it is difficult to ensure high machining accuracy only with ordinary machine tools, so it is necessary to use precision machine tools for processing, in order to make mold parts, especially concave molds with complex shapes, concave mold holes and cavity processing More automation, to reduce the workload of fitter repairs, it is necessary to use CNC machine tools to process mold parts.
CNC cutting is a processing method that rationalizes cutting and is also a common process in aluminum alloy precision processing. It uses end mills with multi-directional cutting functions, spiral cutting interpolation, and contour cutting interpolation. It is selected A few props are used to process a small number of holes. The unique advantage of CNC machining of aluminum alloy precision parts is that the ball end mill can be used with spiral interpolation to continuously process taper holes; the use of ball end mills and spiral interpolation The drill bit can be used for boring and chamfering processing; the end milling cutter can be used with equal height cutting interpolation to perform semi-finishing and precision parts processing on the hole. The end milling cutter used for thread processing can be used with spiral interpolation. Kind of threaded hole processing.
