When precision cnc processing plants produce products, small mistakes of operators often lead to product deformation, which affects the production efficiency of the enterprise. So how to reduce the deformation of CNC machining of mechanical parts? Let's take a look.

Heat treatment processing: For parts, due to various reasons, the product is prone to bending after heat treatment. On the one hand, there will be a bulge in the middle, and the plane deviation will increase, which is caused by the improper operation of the operator, but this situation rarely occurs in our company; on the other hand, due to the influence of various external factors, there is bending phenomenon in the fixture. These deformation problems are not only due to the change of internal stress after heat treatment, but also because the operators have weak professional knowledge and lack of understanding of the structural stability of the product, which increases the probability of part deformation. It is also important to read the drawings accurately and carefully and process mechanical parts according to the drawings.

Too tight clamping: Precision cnc machining often uses auxiliary tools to clamp products. In order to avoid vibration during cnc processing of products, this method is adopted, but there will also be some situations similar to heat treatment. At this time, adjust the clamping force according to the position of the clamping point to increase the contact area between the clamp 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 the lack of rigidity of the product or the tool, affected by the cutting force, the product is thicker at the top and thinner at the bottom, which is called the phenomenon of tool giving. The way to deal with this phenomenon is to improve the sharpness of the blade and reduce the frictional resistance between the blade and the workpiece.
