The Necessity of Polishing Processing
When polished, prototype has distinctions on shape and structure. If the shape is
not special,there is no much difference to finished-product when polished.
We should choose different abrasive paper. At first we can choose some rather
rough abrasive paper to polished rough selvage and then process with more
detailed polishing.According to different requirement of surface, the level of
polishing would be different.After polishing, prototype should be sprayed
some putty to make the roughness of surface more obvious and check
problem existed. So at this time, when amended, it would be targeted
until all polishing have finished.
The three functions of polishing processing
First, strengthening the adhesive force of painting. Before paint new film,
the old film should be polished. So after polished, the adhesive force of
prototype will be strengthened.
Second, for base material, polishing mainly clean the rag and oil pollution
and dust on surface.
Third, smoothness. The surface raw material is rough generally.
So polishing can reduce the roughness of surface.
To prototype, polishing is a necessary job. Because it can remove impurity,
deburr ,and make prototype surface more smooth.
