In order to meet people's demand for the diversity and high quality of aluminum alloy shell products, it is necessary to pay attention to the processing of aluminum alloy shells. How to process aluminum alloy shells? The processing of aluminum alloy shells requires that the control system can logically process programs with control codes or other symbolic instruction rules, and decode them by the computer, so that the machine tool can move and process parts. After cutting by the tool, the blank is processed into semi-finished product parts and so on.

　　 (1) Cutting: Cut the aluminum alloy tube into a single piece, leaving a margin of 2 mm on one side;

　　(2) The left end of the aluminum alloy pipe cut into a single piece is clamped, and the right end face is flat. The inner and outer circles of the car meet the size requirements; ensure the surface roughness requirements; sharp-angle deburring;

　　 (3) U-turn flat end face to size requirements; left side of the car, inner and outer circle to size requirements; to ensure the surface roughness requirements; sharp-angle deburring;

　　 (4) Use thimble to hold the two ends, and finish turning the outer circle to the size requirements, and ensure the surface roughness requirements; sharp-angle deburring;

　　 (5) Milling the inner arc to the size requirement, deburring at acute angles. The aluminum alloy shell processed by the processing technology of the invention has good dimensional consistency and high product qualification rate, and is very suitable for mass production.

Cutting is a processing method that makes the cutting process more rational, and it is also a common process in the processing of aluminum alloy shells. It uses end mills with multi-directional cutting functions, spiral cutting interpolation, and contour cutting interpolation. It uses as few as possible The tool processes a small number of holes.

The ball-end milling cutter cooperates with the spiral interpolation method for continuous processing of taper holes; the ball-end milling cutter and the drill bit with spiral interpolation can be used for boring and chamfering processing; the end milling cutter cooperates with the contour cutting interpolation , Can carry out semi-finish machining and fine parts machining; the end milling cutter used for thread machining can cooperate with spiral interpolation method, which can carry out all kinds of threaded hole machining.

If high-efficiency aluminum alloy fine parts processing is performed on high-precision holes of arbitrary scale, tool interpolation 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 to perform high-speed and high-precision hole processing on a variety of processed materials.
