Aluminum alloy precision parts and products are very popular due to their light weight and exquisite appearance, and they are more and more widely used in industrial fields 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 getting stronger and stronger. Therefore, the better the craftsmanship of aluminum alloy products, the more people will be favored, the greater the market demand will be, and the higher the benefits will be. CNC machining is one of the best machining methods for aluminum alloy shell products at present.
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. Based on years of CNC machining experience, we have summarized the processing skills that should be paid attention to in the processing of aluminum alloy shells.
The technical requirement of CNC machining is that the control system can logically process the program specified by the control code or other symbolic instructions, and decode it through the computer, so as to make the machine tool move and process the parts. The rough material is processed into semi-finished finished parts, etc. by tool cutting.
CNC cutting is a processing method that makes cutting more rational, and it is also a common process in aluminum alloy precision machining. It adopts end mills with multi-directional cutting functions, helical cutting interpolation and contour cutting interpolation. tool to machine a small number of holes.
The ball end mill combined with the helical interpolation method can continuously process the taper hole; the ball end mill and the drill bit with helical interpolation can be used for boring and chamfering; the end mill combined with the equal-height insertion interpolation , semi-finishing and precision parts processing can be performed on holes; end mills for thread processing with helical interpolation method can process various threaded holes.
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 used, the load on each cutter tooth is relatively light, so the same coated carbide end mill can be used for high-speed and high-precision hole machining for a variety of processed materials.
In the process of CNC machining of aluminum alloy shells, it is necessary to master the processing skills of processing technology.
Select a reasonable amount of cutting, and the staff selects the cutting speed to be used according to the material to be processed, the hardness, the state of cutting, the type of material, and the depth of cutting. These conditions are essential for effectively reducing machine wear.
Choose the right tool. When rough turning, generally speaking, it is better to choose high-strength and durable tools, which can better meet the requirements of rough turning.
Choose a reasonable fixture. The parts should fully meet the needs of the machine to reduce unnecessary positioning errors, so it is better to choose a special clamping tool.
Determine a reasonable processing route. Minimize machine processing routes and reduce machine wear.
