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

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

Clamping too tight: auxiliary tools are often used to clamp products during precision hardware processing. In order to avoid vibration during product processing, this method is adopted, but some situations similar to heat treatment will also occur. At this time, adjust the clamping force according to the position of the clamping point, and increase the contact area between the fixture and the workpiece as much as possible. This treatment will be much better, so as to reduce the deformation of precision hardware processing.

Tool cutting: due to the insufficient rigidity of the product or tool and the influence of cutting force, the product is thick at the top and thin at the bottom, which is called the tool giving phenomenon. The way to deal with this phenomenon is to improve the sharpness of the tool edge and reduce the friction resistance between the tool edge and the workpiece.
