Aluminum alloy shells and products are popular due to their lightweight and exquisite appearance, and their applications in industrial and daily necessities fields are becoming increasingly widespread. Especially in recent years, with the development of science and technology and the progress of society, people's demand for product diversity has become increasingly strong. Therefore, the better the process of aluminum alloy shell products, the more they will be favored by people, the greater the market demand, and the higher the efficiency. CNC machining is currently one of the best processing methods for aluminum alloy shell products.
The CNC machining technique requirement for aluminum alloy shell products is that the control system can logically process programs with control codes or other symbolic instructions, and decode them through a computer to make the machine tool operate and process the parts. Cutting rough blanks into semi-finished parts through cutting tools.
CNC cutting is a more rational machining method and a common process in precision machining of aluminum alloys. It uses end mills with multi-directional cutting functions, spiral cutting interpolation, and contour cutting interpolation. It uses as few tools as possible to process a small number of holes.
The ball end milling cutter, combined with the spiral interpolation method, can perform continuous machining of taper holes; Boring and chamfering can be carried out using ball end milling cutters and spiral interpolation drill bits; The end milling cutter, combined with contour cutting interpolation, can perform semi precision machining and precision part machining on holes; The end milling cutter used for thread processing, combined with the spiral interpolation method, can process various threaded holes.
If high-efficiency aluminum alloy shell products are processed for high-precision holes of any size, tool interpolation function can be utilized. Especially when using high-speed milling, the load borne by each tooth is relatively light, so using the same coated hard alloy end milling cutter can perform high-speed and high-precision hole machining on various processed materials.
In the CNC machining process of aluminum alloy shells, it is necessary to master the machining techniques and techniques.
Choose a reasonable cutting amount, and the staff will choose the cutting speed to be used based on the material to be processed, hardness, cutting state, material type, cutting depth, etc. These conditions are essential for effectively reducing machine wear and tear.
Choose the appropriate tool. When rough cutting, generally speaking, it is better to choose high strength and durable cutting tools, which can better meet the requirements of rough cutting.
Choose a reasonable fixture. The parts should fully meet the needs of the machine to reduce unnecessary positioning errors, and it is good to choose specialized fixture clamping tools.
Determine a reasonable processing route. Try to shorten the machining route as much as possible to reduce machine wear and tear.
