What are the ways to reduce the deformation of aluminum profiles after deep processing?

Aluminum profile workpieces may have various deformations in the deep processing process. In addition to the problems of materials, equipment and tools, the processing operation method is also very important. Today, I will introduce the operation skills of deep processing of aluminum profiles.

1. Pay attention to the order of cutting tools, pay attention to processing efficiency in roughing, and cut off as much aluminum as possible in as little time as possible. Therefore, rough machining generally adopts up-cut milling. While finishing pays attention to high precision, it is advisable to use down milling.

2. Precautions for the clamping of thin-walled aluminum profiles. Thin-walled aluminum profiles are easily deformed. Special attention should be paid during deep processing. The clamping should not be too tight or too loose. Loosen the jig a little near the end of the process to allow the workpiece to regain its shape, and then press it lightly. This is a very test of the level of workers.

3. Properly select symmetrical processing. For parts with large machining allowance, for better processing heat dissipation, symmetrical processing can be selected.

4. Workpieces with many cavities can be processed in layers and multiple times. For the processing of multiple cavities, if they are processed one by one in sequence, the workpiece will be deformed due to uneven stress. Multi-layer processing is used to process each layer to each cavity. This processing deformation can be greatly reduced.

5. Pay attention to the chip space of the milling cutter when processing aluminum profiles with a cavity. If the milling cutter is directly stuck, it may cause insufficient chip space and cause the aluminum profile parts to overheat, expand, chip, and break. First drill with a drill bit of the same size or one size larger than the milling cutter, and then mill it with the milling cutter.
