What kind of effect will the cnc prototype machining have on the parts if it is too rough?



If the operation of cnc prototype machining is particularly rough, then cnc machining will have an irreversible effect on the parts, making the processed products a waste. To be more specific, it will affect the wear resistance. The rougher the CNC product processing surface, the smaller the useful contact area between the mating surfaces, then the greater the pressure and the greater the conflict resistance, resulting in faster wear.

Then cnc prototype machining will also affect the stability of the fit. For the clearance fit, the rougher the surface, the easier it is to wear, so that the clearance gradually increases during the work process. For the interference fit, due to the When the convex peaks are squeezed flat, the essential useful interference will be reduced, and the connection strength will be reduced to form precision hardware.

Fatigue strength is also affected during machining. The rough parts have large troughs on the surface. They are the same as sharp notches and cracks, so they are very sensitive to stress collection, which further affects the fatigue strength of the parts. It affects the sealing performance, and the rough surfaces cannot be closely adhered to each other. The passage of gas or liquid can easily lead to the leakage of cracks between the contact surfaces.
