1. The feature and description of the polishing machine The use of the polishing machine can solve the problem of difficult sanding of the concave and convex surface, and also can smooth the plain plate workpiece and the paint workpiece, and make the unevenness more round. But the machine is not perfect, and its function is slightly different for different workpieces. Its main purpose is to reduce the sanding area and improve the sanding efficiency . Matters need to be mentioned when using the machine : 1. The machine is not a powerful sander and cannot sand all objects that are higher than the panel. It just makes the bumpy structure more rounded. The gauze strips and sisal in the special-shaped sander will fluctuate according to the unevenness of the surface of the actual workpiece. When the hardness of the protrusions on the surface of the workpiece is less than the hardness of the gauze strips and sisal, the protrusions will be sanded out, otherwise Smooth. 2. The polishing machine is very sensitive to the place of the rhombus. The bigger of the sanding pressure, the rounded will be more obvious . According to the normal sanding pressure and the hardness of the workpiece, the angle at which the plain plate workpiece is poured out is basically around R0.5. The pouring angle of the paint workpiece is basically around the R1 range. 3. The machine is more sensitive to the rhomboid part that is higher than
the panel, especially the paint sanding. The paint itself has less adhesion to the rhomboid position. When sanding, the sanding force is heavy because of the rhomboid position Easy to leak bottom. 4. The polishing machine will not have any sanding effect for the dead angle position. The depth is more than 15mm, the angle is 60 ° -90 °, and the clearance is less than 30mm ,thats not in the sanding range. 5. The polishing machine pays attention to man-machine cooperation. People who can do the machine do not need to do it. People who can't do the machine need to check and make up. Complementarity can greatly improve production efficiency. 6. The above problems still not solved in the world. It is difficult for a machine to be perfect. It can only solve and replace a large part of the labor, so as to reduce labor intensity and improve production efficiency.
