With the continuous development of the processing industry, what we use must be processed before it can be completed. Processing must use machines to reduce product defects. CNC parts processing in Dongguan is one of them. What consequences will CNC rough processing have on parts?

1. Influencing wear resistance: The rougher the surface of CNC processing, the smaller the effective contact area between the surfaces, the greater the pressure, the greater the friction resistance, and the faster the wear.

2. Influencing the stability of fit: For gap fit, the rougher the appearance, the easier the wear and tear, and the clearance gradually increases in the working process; for interference fit, the effective interference in practice is reduced by extruding the micro-convex peaks during assembly, and the cohesion strength is reduced.

3. Influencing fatigue strength: There are large troughs on the surface of rough parts. Like sharp notches and cracks, they are sensitive to stress concentration, thus affecting the fatigue strength of parts.

4. Influences on corrosion resistance: Rough parts are easy to make corrosive gases or liquids penetrate into the metal inner layer through micro-valleys of the outer surface, forming external corrosion.

5. Influencing sealability: Rough appearance can not be closely fitted, gas or liquid leakage through the gap between the contact surfaces.

6. Influencing contact stiffness: Contact stiffness is the ability to resist contact deformation when the parts are separated by external forces. The stiffness of the machine depends to a great extent on the contact stiffness between the parts.

7. Influencing the measuring accuracy: The surface roughness of the measured parts and measuring tools will directly affect the measuring accuracy, which is in the fine measurement.
