How about the prototype model in addition to the knife marks on the plastic surface?
How about the prototype model in addition to the knife marks on the plastic surface? Regarding this issue, let the editor of Shenzhen prototype model give you a detailed explanation, let's take a look! Hope it helps you.
As we all know, no one is perfect, and the prototype model is no exception. In the process of CNC processing, the prototype model of the prototype will more or less leave some flaws, such as knife marks, burrs, etc., and what we have to do is to minimize the flaws, and strive to make the surface of the prototype model smooth and flat, which is convenient for the next process. . Today, I will focus on the plastic prototype model and talk about the methods to deal with the defects of the plastic prototype model.
When the plastic hand model is CNC processed, the blades are not flat, the cutting force is large during processing, and the clamping is not secure, which will leave knife marks on the surface. These knife marks can be seen with the naked eye but cannot be touched by the hand. Therefore, treatment is required, and the specific method is to use sandpaper for sanding or polishing.

Hand model polishing
There are different grades of sandpaper, the smaller the number, the coarser the sand, the larger the number, the smaller the sand. When polishing, use coarse sandpaper first, and then use fine sandpaper, so that the polished prototype model is smoother. If the order of the sandpaper is reversed, the effect will be greatly reduced. During this period, some ash spraying can be used to test the effect and quality of manual polishing.
