When precision CNC machining manufacturers process products, minor operator errors often lead to product deformation, thus impacting production efficiency. So how can CNC machining deformation be reduced?

Heat treatment: Precision CNC machining of parts is prone to warping after heat treatment for a variety of reasons. Firstly, a bulge may appear in the center and plane deviation may increase. This is often caused by operator mishandling, but this rarely occurs at our company. Secondly, the fixture may bend due to various external factors. These deformation issues are not only due to changes in internal stress after heat treatment, but also due to the operator’s limited professional knowledge and lack of understanding of the product’s structural stability, increasing the likelihood of part deformation. It is also important to read the drawings accurately and carefully and process mechanical parts according to the drawings.

Over-tightening: Precision CNC machining often uses auxiliary tools to clamp the product. This method is used to prevent vibration during CNC machining, but it can also cause some problems similar to heat treatment. In this case, adjust the clamping force according to the position of the clamping point to maximize the contact area between the fixture and the workpiece. This approach will significantly improve the quality of the product, reducing deformation during precision CNC machining.

Tool cutting: Due to insufficient rigidity of the product or tool, the cutting force can cause the product to be thicker at the top and thinner at the bottom, a phenomenon known as tool feed. This phenomenon can be addressed by increasing the sharpness of the blade and reducing friction between the blade and the workpiece.
