The performance of CNC precision machining is very important. It has a huge stake in corporate interests and personal safety. While bringing economic benefits to enterprises, 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 hardware machining. The operator needs to comprehensively consider various factors and take corresponding and effective preventive measures to prevent the product from being deformed in the process of precision CNC machining, so that the finished parts are consistent with the requirements of the drawings in order to be used normally. In order to achieve this, it is necessary to analyze the causes of deformation phenomena in CNC machining of mechanical parts. When precision metal CNC processing plants produce products, small mistakes by operators often lead to product deformation and affect the production efficiency of enterprises. So how to reduce the processing deformation of mechanical parts?
Heat treatment processing: parts processing, due to a variety of reasons, the product is prone to bending after heat treatment. On the one hand, there will be a bulge phenomenon in the middle, and the plane deviation will increase. This is caused by improper operation by the operator, but this is rarely the case in our company; On the other hand, due to the influence of various external factors, the phenomenon of clamping 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 the structural stability of the product is not understood, which increases the probability of part deformation.
Clamping too tight: When the product is CNC machined with precision hardware, it is often necessary to use auxiliary tools for clamping. This method is used to avoid vibrations during product processing, but there are some cases similar to heat treatment. In this case, the clamping force is adjusted according to the position of the clamping point to maximize the contact area between the clamping and the workpiece. This treatment will be much better and can reduce the distortion problem of precision metal machining.
Tool cutting: due to the lack of rigidity of the product or tool, affected by the cutting force, the upper thickness and lower thickness of the product are deformed. The magnitude of the frictional resistance of the workpiece.
