Aluminum alloy precision parts and products are popular because of their light weight and exquisite appearance, and they are more and more widely used in industrial 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 has become stronger and stronger. Therefore, the better the process of aluminum alloy products is, the more they will be favored by people, the greater the market demand, and the higher the efficiency. CNC processing is currently one of the best processing methods for aluminum alloy shell products.
In order to meet people's needs for the diversity and high quality of aluminum alloy shell products, process skills must be summarized in the processing process. Based on years of CNC machining experience, Zonsan Precision summarizes the processing skills that should be paid attention to in aluminum alloy shell processing.
The requirement of CNC machining skills is that the control system can logically process the program with the control code or other symbolic instructions, and decode it by the computer, so that the machine tool can move and process the parts. The rough material is processed into semi-finished finished parts by cutting tools.
CNC cutting is a processing method that makes the cutting more reasonable, and it 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, etc., it chooses as few as possible The tool is used to process a small number of holes.
Ball end mills can be used with spiral interpolation to continuously process taper holes; ball end mills and spiral interpolation drills can be used for boring and processing; end mills can be used with contour cutting interpolation , Can carry out semi-finish machining and precision parts machining on holes; the end milling cutter used for thread machining can be used for various threaded hole machining with spiral 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 used, the load on each tooth is relatively light. Therefore, the same coated carbide end mill can be used for high-speed and high-precision hole processing of multiple materials.
In the CNC machining of aluminum alloy shells, the machining process must be mastered.
Choose a reasonable amount of cutting, and the staff can choose the cutting speed to use according to the material to be processed, the hardness, the cutting state, the type of material, and the depth of cutting. These conditions are necessary to effectively reduce machine wear.
Choose the right tool. When rough turning, generally speaking, it is better to choose a high-strength and durable tool, so that it can better meet the requirements of rough turning.
Choose a reasonable fixture. The parts must fully meet the needs of the machine in order to reduce unnecessary positioning errors, and it is better to choose a special fixture clamping tool.
Determine a reasonable processing route. Try to shorten the machining route and reduce the wear of the machine.
Peaches and plums, the next from Seikei. Zonsan Precision has explored and summed up a set of effective machining experience and skills during the 7 years of CNC machining of aluminum alloy shells. In the actual processing and production process, the application of these mature CNC machining experience has greatly improved the CNC machining quality and quality of the aluminum alloy shell. This is also the reason why Zonsan Precision's CNC machining business of aluminum alloy shells is not weak in the off-season.
