Precautions for CNC machining of aluminum alloy

No matter what kind of work, there must be some matters to pay attention to in this process, so as to better ensure our work efficiency and product quality. Now aluminum alloy is widely used with high-precision instruments, so the requirements are higher and higher. At this time, whether it is manufacturing or processing, what matters should be paid attention to in CNC processing of aluminum alloy?

1. The speed of white steel knife should not be too fast.
2. When the workpiece is too high, please thicken it with a knife of different grade length.
3. After roughening with a rough knife, remove the excess with the knife, and grind the knife after ensuring the excess.
4. The plane is processed with flat bottom edge instead of ball edge to reduce processing time.
5. The four corners of the calibration plane must be flat.
6. The inclination is an integer, which is processed with an inclined cutter, such as tube position.
7. Before each work, want to clear the remaining amount of the previous work after processing, to avoid empty tool and redundant processing.
8. Try to take a simple path. For example, shape, trenching, avoiding single side, lapping, etc.
9. When taking wcut, if you can go to finish, please don’t take rough.
10. In the case of shape light knife, the light should be coarsened first and then exposed. When the workpiece is too high, it should be illuminated first and then.
11. The tolerance should be set reasonably to balance the machining accuracy and computer calculation time. The tolerance is set to 1 / 5 of the remaining value when it is turned on, and 0.01 for a light knife.
12. Add more projects to reduce the time of empty knife. Think more and reduce the chances of mistakes. Increase the auxiliary surface of the auxiliary line slightly to improve the processing condition.
