在手板模型行業中，打磨可以說是手板制作過程中必經的一個環節，手板經過cnc加工之后，表面會產生很多毛刺和刀痕，這樣都需要進行打磨處理，一般會選擇砂紙進行打磨，或者選擇使用拋光機進行拋光。

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.

濟南手板打磨的方法：

Method for polishing Jinan hand board:

（1）機械打磨：大面積施工時，為了提高工作效率，可采用機械打磨方法，如電動打磨機圓盤式和振動式。

(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）干打磨：采用砂紙進行打磨，適用于硬而脆的漆種的打磨，其缺點是操作過程中將產生很多粉塵，影響環境衛生。

(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）濕打磨：用水砂紙蘸水能減少磨痕，提高涂層的平滑度，并且省砂紙、省力，但水磨后應注意噴涂下層油漆時，一是要等水磨層完全干透后才能涂下層油漆，否則漆層很容易泛白，另吸水性很強的底材也不宜水磨。

(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.

手板打磨時需要注意的問題：

Precautions for hand board polishing:

1.進行粗加工打磨選擇一些很粗的砂紙，去掉表面很粗的毛刺之后再進行細紋的打磨，砂紙可以分為220，400，800，1000等等不同的等級，號越大砂紙越細，反之號越少砂紙就越粗。

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.

2.一般表面較為粗糙，需要通過砂磨獲得較平整的表面，因此打磨可以降低手板表面的粗糙度的作用。

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.
