Aluminum alloy fine parts and products are popular due to their lightweight and exquisite appearance, and are increasingly widely used in industrial and daily necessities fields. Especially in recent years, with the development of science and technology and the advancement of society, people's demand for product diversity has become increasingly strong. Therefore, the better the process of aluminum alloy products, the more they will be loved by people, the greater the market demand, and the higher the efficiency. Aluminum alloy CNC machining is currently one of the best processing methods for aluminum alloy shell products.

In order to meet people's diverse and high-quality demands for aluminum alloy shell products, it is necessary to summarize process skills during the processing process. Based on years of CNC machining experience, the author summarizes the processing skills that should be paid attention to in the processing of aluminum alloy shells.

The requirement for CNC machining skills of aluminum alloy is that the control system can logically process programs with control codes or other symbol instruction rules, and decode them through a computer to make the machine tool operate and process parts. After cutting with a cutting tool, the raw material is processed into semi-finished product parts, etc.

CNC cutting is a machining method that makes cutting more reasonable and is also a common process in fine machining of aluminum alloys. It uses methods such as end mills with multi-directional cutting function, spiral cutting interpolation, and contour cutting interpolation, and uses as few tools as possible to process a few holes.

The ball end milling cutter cooperation spiral interpolation method can be used for continuous processing of taper holes; Using a ball end milling cutter and a spiral interpolation drill bit, it can perform boring and chamfering processing; Collaborating with end mills and other high cutting interpolation methods, it can perform semi precision machining and fine part machining on holes; The vertical milling cutter used for thread processing can be used for various thread hole processing using the spiral interpolation method.

If high-precision holes of arbitrary sizes are processed with high-efficiency aluminum alloy precision parts, tool interpolation function can be used. Especially when selecting high-speed milling, the load accepted by each tooth is relatively light, so using the same coated hard alloy end milling cutter can perform high-speed and high-precision hole processing on various processed materials. With the improvement of daily standards and the qualitative leap in daily quality, many people are thinking about how to improve quality, and the same goes for craftsmanship. The better the craftsmanship, the more market demand, and the higher the efficiency. The CNC machining process of aluminum alloy is the only one with good shell processing technology, and customers' requirements for CNC machining are also increasing. What are the detailed technical requirements for CNC machining process of aluminum alloy?

1) Reasonably select the cutting amount, and the operator selects the cutting speed to be used based on the required data, hardness, cutting status, variety of data, depth of cutting, etc. These conditions are ideal for maintaining machine wear and tear conditions effectively.

2) Choose suitable props. When rough cutting, generally speaking, it is better to choose high strength and durable cutting tools to better meet the requirements of rough cutting.

3) Choose a reasonable fixture. The parts should fully meet the requirements of the machine to reduce unnecessary positioning errors and facilitate the selection of specialized fixture clamping tools.

4) Confirm the processing path before homework. Try to shorten the road for machine processing as much as possible to reduce machine wear and tear
