Aluminum alloy is an important industrial raw material. Because of its small hardness and large thermal contraction coefficient, it is easy to deform when processing thin -walled plate parts. In addition to improving the performance of the tool and eliminating the internal stress of the data by adopting timeliness processing in advance, in terms of processing technology, you can also bring some wrists to minimize the processing deformation of the data. Then, then
Regarding the processing waste of large aluminum alloy parts, in order to create better heat dissipation conditions and reduce thermal deformation, it is necessary to prevent heat concentration, and symmetrical processing can be adopted. For example, there is a 90mm thick aluminum alloy plate that needs to be milling to 60mm thick. If the side of the milling side is turned over and milling the other side, because each side is a processed size, and the continuous processing remaining amount is large, which will form a calorie calorie. Concentration problem.
In this way, the plane of the aluminum alloy board can only reach 5mm. If the symmetrical processing method of double -sided repeated cutting is used, each surface is processed at least twice, reaching the size after reaching, which is conducive to heat dissipation, and the flatness can be controlled at 0.3mm.

The layered repeated processing method When the aluminum alloy plate has multiple cavities that need to be processed, if a type of cavity is processed in sequence, it is easy to make the cavity wall wrap and deform due to uneven pressure. Good treatment is to take layered repeated processing methods, that is, to stop processing all types of cavity at the same time, but it is not a one -time processing, but a multi -layer processing to the size of the demand. In this way, the force of parts will be relatively average, and the probability of deformation will be small. Customized aluminum alloy processing
Just choose the appropriate cutting dosage to effectively reduce the cutting force and cutting heat in the cutting process. During the mechanical processing process, the amount of cutting is too large, resulting in a large cutting force, which is easy to form parts deformation, which will affect the rigidity of the main axis of the machine tool and the durability of the tool. In each element of cutting, cutting force is a tool that affects greater influence.
It should be said that reducing back -cutting volume is conducive to ensuring the non -deformation of the parts, but it will also reduce processing efficiency. CNC high -speed milling processing can solve this problem. Only by reducing the amount of the knife and the corresponding feed and improving the speed of the machine tool can the cutting force be reduced and the processing efficiency can be ensured.
