What factors can cause deformation in CNC machining parts?
When precision CNC machining plants produce products, small errors by operators often lead to product deformation, thereby affecting the production efficiency of the enterprise. So how to reduce the deformation of CNC machined mechanical parts? Let's take a look.
Heat treatment processing: For precision CNC machining of parts, due to various reasons, the product is prone to bending after heat treatment. On the one hand, there will be bulges in the middle, and the plane deviation will increase, which is caused by improper operation by operators. However, this situation rarely occurs in our company; On the other hand, due to various external factors, the fixture exhibits bending phenomenon. These deformation problems are not only due to changes in internal stress after heat treatment, but also due to weak professional knowledge of operators and lack of understanding of the structural stability of the product, which increases the probability of part deformation. It is also important to accurately and carefully read the drawings and process mechanical parts according to them.
Tight clamping: precision CNC machining often uses auxiliary tools to clamp products. To avoid vibration during CNC machining of products, this method is adopted, but there may also be some situations similar to heat treatment. At this point, adjust the clamping force according to the position of the clamping point, and try to increase the contact area between the fixture and the workpiece as much as possible. This treatment will be much better, thereby reducing the deformation of precision CNC machining.
Tool cutting: Due to insufficient rigidity of the product or tool, it is affected by cutting force, resulting in a thicker top and thinner bottom of the product, which is called tool feeding phenomenon. The method to deal with this phenomenon is to improve the sharpness of the blade and reduce the frictional resistance between the blade and the workpiece.
