1. Select the processing standards. The selection of rough standards is as high as possible as possible on the surface layer with a large, flat, and relatively large area. Some of the hair edges, wool edges, and rustic residues on the benchmark point should be removed to ensure accurate positioning and accurate positioning. Reliable. The precision standards should be as consistent with the design scheme standards, installation standards, and accurate measurement standards. And the processing process should take into account the reliability of parts during processing, accurate positioning accuracy, and clamping stability.

2. Rough processing, because the precision and appearance roughness of the processing specifications of aluminum alloy profiles are not easy to achieve high precision regulations. During the entire processing process, the processing capacity of each processing surface, especially the complicated thick wall parts, is more complicated. Remove it before finishing. During the entire process of workpiece, the surface of the workpiece has been continuously rubbed, which will make the surface crystal of the workpiece change and shift, resulting in hard bottoming conditions. At the same time, the cutting heat also causes the cutting shape. deformation.

3. Formed precision processing, use a facilities with higher precision to perform parts of parts of the parts. Generally, milling machines, digital explicit CNC lathes or processing management centers. During the entire process of fine processing, because the processing capacity is small, the high cutting rate and the amount of small knife are selected on the selection of the knife to ensure that the knife has sufficient strength stiffness, reducing the precision of processing precision caused by cutting vibration vibration vibration vibration. reduce. In the process of installation of the workpiece, try to avoid the frequency of clamping, implement a precise positioning forming, and increase the smaller clamping force to reduce human factors.

4. Effective selection of clamping methods, although the accurate positioning of the parts has been applied, the aluminum alloy -type thick wall parts are relatively low and the stiffness is relatively low, which can easily cause the clipping change. The design scheme stipulates that there will be no drum -type or wavy surface. Before processing, you can modify a dedicated support point in the middle of the plane map. The support point consists of the car chassis and adjustment of the extruder screw.
