Aluminum products need to go through different processing methods before they can adapt to various working environments and provide better working performance. However, during the processing of aluminum products, due to errors in the fabrication flow or improper personal technical operation, it is easy to cause deformation of aluminum processing. Jiang Yin Ming Ding Aluminum Products Co., Ltd. provides you with four technological measures to reduce the deformation of aluminum fabrication.
1. Reduce the internal stress of the blank
Using natural or artificial aging and vibration treatment can partially eliminate the internal stress of the blank, and can also be processed in advance. When processing large blanks, because there are many processed parts, it is also easy to deform. This requires pre-processing to remove excess parts and reduce the probability of deformation. During the placement time after pre-processing, the internal stress can also be released.
2. Improve the cutting ability of the tool
The material and geometric parameters of the tool have an important influence on the cutting force and cutting heat of the tool. Choosing the right tool can reduce the chance of machining deformation of the part.
To improve the cutting ability of the tool, these two aspects need to be achieved: ① reasonable selection of the geometric parameters of the tool; ② improvement of the tool structure
3. Improve the clamping method of the workpiece
For thin-wall aluminum parts with poor rigidity, the method of clamping can be used to reduce the possibility of deformation:
① For thin-walled bushing parts, the axial end surface compression method with better rigidity should be used, and the three-jaw self-centering chuck or spring chuck cannot be directly used to clamp in the radial direction.
②When processing thin-walled and thin-plate aluminum parts, it is best to use vacuum suction cups, and then use a smaller amount of cutting to process.
4. Reasonably arrange the process
Before processing aluminum, it is necessary to evaluate the aluminum parts and then decide how to arrange the processing procedures.
