The performance of CNC precision machining is very important. It has a huge relationship with corporate interests and personal safety. While bringing economic benefits to the enterprise, it can also effectively reduce the occurrence of safety accidents. Therefore, it is inevitable to encounter the problem of deformation of parts in the process of precision metal processing.

The operator needs to comprehensively consider various factors and take corresponding effective preventive measures to prevent the product from being deformed during the precision cnc machining process, and to make the finished parts consistent with the drawing requirements before they can be used normally. In order to achieve this goal, it is necessary to analyze the causes of deformation phenomena in cnc machining of mechanical parts. When the precision metal cnc processing factory produces products, small mistakes of operators often lead to product deformation and affect the production efficiency of the enterprise. So how to reduce the processing deformation of mechanical parts? let's see.

Heat treatment processing: Parts processing, 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. This is caused by improper operation by the operator, but this situation rarely occurs in our company; on the other hand, due to the influence of various external factors, clamping and bending will occur. These deformation problems are not only caused by the change of internal stress after heat treatment, but also because the operator's professional knowledge is not solid, and he does not understand the structural stability of the product, which increases the probability of part deformation. It is also important to read the drawings accurately and carefully,

Too tight clamping: When the product is used, it is often necessary to use auxiliary tools for clamping. In order to avoid vibration during product processing, this method is adopted, but there are also some cases similar to heat treatment. At this time, adjust the clamping force according to the position of the clamping point to maximize the contact area between the clamp and the workpiece. This treatment is much better and can reduce the deformation problem of precision metal machining.

Tool cutting: Due to the insufficient rigidity of the product or the tool, it is affected by the cutting force, resulting in deformation of the upper and lower thickness of the product. The size of the frictional resistance of the workpiece.
