CNC machining technique of aluminum alloy shell

Aluminum alloy precision parts and products are popular because of their light weight and delicate appearance. They are 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. Accordingly, the craft that aluminium alloy product does better, more can be favored by people, market demand also is met bigger, benefit is higher also. CNC machining is one of the best machining methods for aluminum alloy shell products.

In order to meet the needs of people on the diversity of aluminum alloy shell products, high quality, in the process of processing must be summarized technology skills, Changhong precision according to years of CNC processing experience, summed up the aluminum alloy shell processing should pay attention to the processing skills.

CNC processing skills requirements is that the control system can logically process the control code or other symbol instructions provided by the program, through the computer decoding, so as to make machine movements and processing parts. The blank is processed into semi-finished parts by cutting tools.

CNC cutting is to make the cutting process more reasonable processing, is also a common process of aluminum alloy precision processing, the use of multi-direction cutting function of end milling cutter, spiral cutting interpolation and contour cutting interpolation and other ways, it uses as few tools to process a small number of holes.

Ball end milling cutter with spiral interpolation method can be used to process taper hole continuously. Boring and chamfering can be carried out by using ball end milling cutter and spiral drilling bit. End milling cutter with equal height cut interpolation, the hole can be semi-finishing and precision parts processing; Screw milling cutter with screw interpolation method, can be used for all kinds of screw hole processing.

If high-efficiency aluminum alloy precision parts are machined for high-precision holes of any size, the tool interpolation function can be used. Especially when high speed milling is used, the load of each cutter tooth is relatively light, so the same coated carbide end milling cutter can be used for high speed and high precision hole machining of various materials.

In the aluminum alloy shell CNC machining process must master the processing technology and processing skills.

Select a reasonable amount of cutting, the staff according to the need to be processed material, hardness, cutting state, type of material, cutting depth of choice of the use of cutting speed. These conditions are essential for effectively reducing machine wear.

Choose the right tool. Rough car, generally speaking, the best choice of high strength, durable tool, so that you can better meet the rough car is required.

Choose a reasonable fixture. Parts should fully meet the needs of the machine, in order to reduce unnecessary positioning error, the best choice of special fixture clamping tools.

Determine the reasonable processing route. As far as possible to shorten the machine processing route, reduce the wear of the machine.
