CNC processing of aluminum parts is a high-precision processing. During the CNC processing of aluminum parts, the quality is guaranteed according to the following steps:
1. Ensure the accuracy of CNC machine tools. CNC machine tools are the carrier of CNC machining of aluminum parts. Ensuring the accuracy of CNC machine tools is an important basis.
2. The choice of tool, the tool is the top priority of cnc processing, a good tool can get twice the result with half the effort. Aluminum CNC machining high-speed steel cutting tools and special aluminum alloy cutting tools are ideal choices.
3. When processing aluminum parts, the tool speed should be processed with high speed and high feed, and the margin should be small. Because aluminum alloy is relatively soft compared to steel, it is easy to stick to the knife when the speed is low, which will also reduce the processing efficiency. If it is finishing machining, it is necessary to ensure the smoothness of the aluminum parts, and the feed rate can be appropriately reduced.
4. The choice of cutting fluid. Although cutting fluid is only an auxiliary material in cnc machining of aluminum parts, the choice of cutting fluid is also very important. Semi-synthetic cutting fluid should be used for CNC machining of aluminum profiles, which is conducive to smooth chip removal.
5. Reduce the amount of deformation after cutting. This problem is often encountered in cnc processing of aluminum parts. The accuracy is very high when measuring the size just after processing, but there will be slight deformation after a period of time. Although it is not visible to the naked eye, it can be found that the dimensional tolerance has become larger with measuring tools. This situation is a kind of stress deformation. In order to reduce stress deformation, it is necessary to reduce the vibration during processing, and add a process of eliminating internal stress after rough machining and before finishing. This can alleviate the situation of processing deformation.
