With the continuous development of the processing industry, the things we use need to be processed to complete, and the processing needs to be used to the machine to reduce the defects of products. CNC parts processing is one of them. So what kind of consequences will be caused to the parts if the CNC machining is particularly rough?
- Influence on wear resistance: the rougher the machining surface of CNC products is, the smaller the effective contact area between matching surfaces is, the greater the pressure is, and the greater the friction resistance is, the faster the wear is.
- Affect the stability of the fit: for the clearance fit, the rougher the surface is, the easier it is to wear, making the intermediate gap gradually increase during the working process; for the interference fit, due to the micro convex peak being flattened during assembly, the practical effective interference is reduced and the connection strength is reduced.
- Influence on fatigue strength: there are large wave troughs on the surface of rough parts, which are sensitive to stress concentration like sharp corner notches and cracks, thus affecting the fatigue strength of parts.
- Affect the corrosion resistance: rough surface of parts, easy to make corrosive gas or liquid penetrate into the inner layer of metal through the micro Valley on the surface, forming external corrosion.

- Affect the sealing: rough surfaces can not fit tightly, and gas or liquid leak through the gap between contact surfaces.
- Influence on contact stiffness: contact stiffness is the ability of part separation surface to resist contact deformation under the action of external force. The stiffness of a machine depends largely on the contact stiffness between the parts.
- Affect the measurement accuracy: the surface roughness of the measured surface of the part and the measuring surface of the measuring tool will directly affect the measurement accuracy, especially in the fine measurement.
