Aluminum alloy precision parts and products are popular because of their light weight and exquisite appearance. They are more and more widely used in the field of industry and daily necessities. Especially in recent years, with the development of science and technology and the progress of society, people's demand for product diversity is becoming stronger and stronger. Therefore, the better the process of aluminum alloy products is, the more people will favor it, the greater the market demand and the higher the benefit. Aluminum alloy CNC processing is one of Zui good processing methods for aluminum alloy shell products.

In order to meet people's demand for the diversity and high quality of aluminum alloy shell products, the process skills must be summarized in the processing process. According to many years of CNC processing experience, the author summarizes the processing skills that should be paid attention to in the processing of aluminum alloy shell.

The requirement of aluminum alloy CNC machining technology is that the control system can logically process the program with control code or other symbolic instructions, and decode it by computer, so as to make the machine tool act and process parts. The blank is processed into semi-finished parts by tool cutting.

CNC cutting is not only a processing method to make the cutting process more reasonable, but also a common process of aluminum alloy precision machining. It adopts the end milling cutter with multi-directional cutting function, spiral cutting interpolation and contour cutting interpolation. It selects as few tools as possible to process a small number of holes.

Ball end milling cutter combined with spiral interpolation method can process taper hole continuously; Boring and chamfering can be carried out by using ball end milling cutter and spiral interpolation bit; End milling cutter with contour cutting interpolation can carry out semi precision machining of holes and precision parts machining; The end milling cutter used for processing threads can be used to process various threaded holes with the screw interpolation method.

If high-efficiency aluminum alloy precision parts are processed for high-precision holes of any size, the tool interpolation function can be used. Especially when high-speed milling is adopted, the load borne by each cutter tooth is relatively light. Therefore, with the same coated cemented carbide end milling cutter, high-speed and high-precision hole machining can be carried out on a variety of processed materials. With the qualitative leap in the quality of life brought about by the improvement of living standards, many people are thinking about how to improve the quality, and so is the process. The better the process is, the more market demand will be and the higher the benefit will be. Good shell processing technology depends on aluminum alloy CNC processing technology, and customers have higher and higher requirements for CNC processing. What are the technical requirements of aluminum alloy CNC processing technology?

1) The cutting amount shall be reasonably selected, and the staff shall select the cutting speed according to the, hardness, cutting state, material type, cutting depth and so on. These conditions are ideal conditions to effectively protect the machine from wear.

2) Select the appropriate props. In rough turning, generally speaking, it is good to choose high-strength and durable tools, which can better meet the requirements of rough turning.

3) Select a reasonable fixture. The parts shall fully meet the needs of the machine to reduce unnecessary positioning errors. It is good to select special fixture clamping tools.

4) Determine the processing route before work. Try to shorten the machining route to reduce the wear of the machine
