Aluminum parts processing technology to solve the problem of aluminum parts processing deformation（5）

Shenzhen aluminum parts processing manufacturers summarize the operation skills to reduce processing deformation

　　The parts of aluminum parts are deformed during the processing. In addition to the above reasons, in actual operation, the operation method is also very important.

　　 1. For parts with large machining allowance, in order to have better heat dissipation conditions during processing and avoid heat concentration, symmetrical processing should be used during processing. If a 90mm thick sheet needs to be processed to 60mm, if one side is milled immediately, the other side will be milled immediately, and the flatness will be 5mm if it is processed to the final size once; if repeated feed symmetrical processing is used, each side will be processed twice The final size can guarantee the flatness reaches 0.3mm

　　 2. If there are multiple cavities on the plate part, it is not suitable to use the sequential processing method of one cavity and one cavity during processing, as it is easy to cause the parts to be unevenly deformed due to uneven force. Multiple layers are used for processing, each layer is processed to all the cavity at the same time, and then the next layer is processed to make the parts evenly stressed and reduce deformation.

　　 3. Reduce the cutting force and cutting heat by changing the cutting amount. Among the three factors of cutting consumption, the amount of back-feeding has a great influence on the cutting force. If the machining allowance is too large, the cutting force of one pass is too large, which will not only deform the parts, but also affect the rigidity of the machine tool spindle and reduce the durability of the tool. If you reduce the amount of back-eating knife, it will greatly reduce production efficiency. However, high-speed milling in CNC machining can overcome this problem. While reducing the amount of back-feeding, as long as the feed is increased accordingly and the speed of the machine tool is increased, the cutting force can be reduced while ensuring the processing efficiency.
