In precision CNC machining, what factors can cause deformation of parts?
The performance of precision cnc machining parts 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 accidents. Therefore, it is inevitable that parts will be deformed in the process of precision metal processing. Operators need to consider various factors and take corresponding effective preventive measures to prevent product deformation during precision machining, so that the parts are consistent with the drawing requirements and can be used normally.
In order to achieve this goal, it is necessary to analyze the machining of mechanical parts. The reason for the deformation. In the production of precision metal processing plants, small errors of the operators often lead to product deformation, which affects the production efficiency of the enterprise. So how to reduce the deformation of mechanical parts? Let’s see.
Heat treatment: For custom cnc milling turning parts, due to many reasons, it is easy to bend after heat treatment. On the one hand, there will be a bulge in the middle and an increase in the plane deviation, which is the result of improper operation by the operator, but such a situation rarely occurs in our company; on the other hand, due to the influence of various external factors, the fixture is bent These problems are not only caused by changes in the 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 well understood, which increases the probability of part deformation. Reading the drawings accurately and carefully and processing them according to the drawings is also very important.
The clamping is too tight: when the product is processed, auxiliary tools are often required for clamping. In order to avoid vibration during product processing, this method is adopted, but there will also be some situations similar to heat treatment. At this time, adjust the position and clamping force of the clamping point, and maximize the contact area between the clamp and the workpiece. This way of treatment will be much better, which can reduce distortion.
Tool cutting: Due to the insufficient rigidity of custom cnc milling turning parts or the tool, it is affected by the cutting force, which causes the product to deform from the upper thickness to the lower thickness.
These causes of product deformation have been analyzed and effective solutions have been adopted. We need to pay attention to the processing of precision cnc machining parts and use them in practice.
