In the handicraft model industry, polishing can be said to be a necessary step in the handicraft production process. After CNC machining, the surface of the handicraft will produce many burrs and knife marks, which require polishing treatment. Generally, sandpaper is chosen for polishing or a polishing machine is used for polishing.
Method for polishing Jinan hand board:
(1) Mechanical polishing: In order to improve work efficiency during large-scale construction, mechanical polishing methods can be used, such as electric polishing machine disc type and vibration type.
(2) Dry polishing: Using sandpaper for polishing, suitable for polishing hard and brittle paint. Its disadvantage is that a lot of dust will be generated during the operation, which affects environmental hygiene.
(3) Wet polishing: Dipping sandpaper with water can reduce grinding marks, improve the smoothness of the coating, and save sandpaper and labor. However, after water grinding, attention should be paid to spraying the lower layer of paint. Firstly, it is necessary to wait for the water grinding layer to completely dry before applying the lower layer of paint. Otherwise, the paint layer is prone to whitening, and the substrate with strong water absorption is also not suitable for water grinding.
Precautions for hand board polishing:
1. For rough machining and polishing, select some very coarse sandpaper, remove the rough burrs on the surface, and then perform fine grain polishing. The sandpaper can be divided into different grades such as 2204008001000, etc. The larger the number, the finer the sandpaper, and vice versa.
2. Generally, the surface is relatively rough and needs to be sanded to obtain a smoother surface. Therefore, sanding can reduce the roughness of the hand board surface.
