Many CNC processing plants, CNC processing level also zigzag. Rough CNC machining can have an unrecoverable impact on parts and become waste.
Shenzhen yuezhengjia technology co., LTD will introduce the influence of rough machining on CNC parts
1. Impact on wear resistance: the rougher the surface of CNC products, the smaller the useful contact area between mating surfaces, the greater the pressure, the greater the conflict resistance, the faster the wear.
2. Influence the stability of fit: for gap fit, the rougher the surface, the easier the wear, so that the gap gradually increases in the process of work; As for interference fit, it reduces the essential useful interference and the connection strength due to the flattening of the mesoscopic convex peak.
3. Impact on fatigue strength: rough parts surface has a large trough, they are like sharp Angle notch and crack, very sensitive to the stress set, thus affecting the fatigue strength of parts.
4. Influence the corrosion resistance: rough parts surface, easy to make the erosion gas or liquid through the surface of the micro concave valley infiltration into the metal inner layer, the formation of surface erosion.
5. Affect the sealing: the rough surface between the not close, gas or liquid through the contact surface crack leakage.
6. Influence on the contact stiffness: the contact stiffness is the strength of the fusion surface of parts to resist contact deformation under the action of external forces. The stiffness of a machine depends largely on the contact stiffness between its parts.
7. Influence measurement accuracy: the surface roughness of the measured surface of parts and the measurement surface of measurement equipment will directly affect the measurement accuracy.
The other, the surface roughness on the parts of the coating, thermal conductivity and contact resistance, reflection strength and radiation function, liquid and fluid flow resistance, conductor surface current smooth all have different levels of influence. So yuezhengjia CNC machining plant in this regard to be very concerned, do not make the same mistake in the production process.
