(1) In order to ensure the processing accuracy of the aluminum alloy CNC, the ZUI is easy to separate. During rough processing, the amount of cutting is large, the cutting force, the high clamping force of the workpiece, the large amount of heat, and the more significant processing of the processing surface. Continuously, the accuracy of the parts after finishing will be lost quickly due to the re -distribution of stress. For parts with high processing accuracy. Before rough processing and precision processing, low temperature degeneration or timeliness processing sequences should also be arranged to eliminate internal stress.
(2) Reasonably choose aluminum alloy CNC processing equipment. Rough machining is mainly to cut off most of the processing waste, and does not require high processing accuracy. Therefore, rough processing should be carried out on machine tools with large power and less accuracy. Machinery processing. Thick and precise processing on different machine tools can not only give full play to the equipment capabilities, but also extend the life of the precision machine tool.
(3) In the aluminum alloy CNC processing process, heat treatment processes are often arranged. The arrangement of the location of the heat treatment process is as follows: In order to improve the cutting performance of metal, such as annealing, positive fire, and quality adjustment, it is generally arranged before mechanical processing. In order to eliminate internal stress, such as time -effective, quality treatment, etc., it is generally arranged before after rough processing, and it is carried out before finishing. In order to improve the mechanical performance of parts, such as carburizing, quenching, and recovery, it is generally arranged after mechanical processing.
