In the 21st century, machinery and equipment to improve the level of processing, cnc precision parts processing more not to mention, in the range, and in the effect more can not be less, with the expansion of the market is now faster and faster, and now the development of machinery and equipment, but the processing strength has not reached the ideal, so that to improve processing technology, or there are certain reasons, now we come to understand how cnc precision parts to improve processing technology it!
Aluminum alloy is one of the most widely used non-ferrous metal materials in industry, and is used in a large number of applications in aviation, aerospace, automobile, machinery manufacturing, shipping, chemical industry and household appliances and daily necessities. With the rapid development of science and technology as well as industrial economy in recent years, the demand for aluminum alloy precision parts is increasing, which makes the CNC machining process of aluminum alloy also conduct more and more in-depth research.
Pure aluminum has small density, low melting point, high plasticity, easy processing, and can be made into various profiles and plates. It has good corrosion resistance. Aluminum alloy is obtained by adding other metal elements to aluminum metal, such as silicon, iron, copper, aluminum, etc. The aluminum alloy obtained by adding other metals has the characteristics of low density, high strength, corrosion resistance, etc. Its characteristics of lightness and strength make aluminum alloy widely used in various parts processing and manufacturing, and aluminum alloy parts are widely used in industry, and in life.
The wide application of aluminum alloy has promoted the development of CNC machining technology of aluminum alloy, and the development of CNC machining technology has expanded the application field of aluminum alloy, so CNC machining technology of aluminum alloy has become a hot spot for research. Aluminum alloy parts machining, also known as CNC machining, automatic lathe machining, CNC lathe machining, etc., its characteristics are used in turning, milling, planing, drilling, grinding and other general-purpose machine tool processing mold parts, and then the necessary clamp repair, assembly into a variety of molds; high precision requirements of mold parts, only with ordinary machine tool processing is difficult to ensure high processing accuracy, and therefore need to use precision machine tools for processing; in order to make the mold parts, especially the complex shape of the convex mold, concave model holes and the mold parts. parts, especially the complex shape of the convex mold, concave model hole and cavity processing more automated, reduce the workload of the clamp repair, the need to use CNC machine tools (such as three-coordinate CNC milling machine, machining center, CNC grinding machine and other equipment) processing mold parts.
CNC cutting is a kind of processing method that makes cutting more rational, and is also a common process of aluminum alloy precision machining, using end mills with multi-directional cutting function, spiral cutting interpolation and equal height tangential interpolation, etc. It uses as few tools as possible to process a small number of holes. The unique advantage of CNC machining of aluminum alloy precision parts is that the ball end mill with helical interpolation method can be used for continuous processing of tapered holes; the use of ball end mills and helical interpolation drills can be used for boring and chamfering; end mills with contour tangential interpolation can be used for semi-finishing and precision parts processing of holes; end mills for processing threads with helical interpolation method can be used for processing various threaded holes.
