在手板模型行业中，打磨可以说是手板制作过程中必经的一个环节，手板经过cnc加工之后，表面会产生很多毛刺和刀痕，这样都需要进行打磨处理，一般会选择砂纸进行打磨，或者选择使用抛光机进行抛光。

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.

济南手板打磨的方法：

Method for polishing Jinan hand board:

（1）机械打磨：大面积施工时，为了提高工作效率，可采用机械打磨方法，如电动打磨机圆盘式和振动式。

(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：采用砂纸进行打磨，适用于硬而脆的漆种的打磨，其缺点是操作过程中将产生很多粉尘，影响环境卫生。

(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）湿打磨：用水砂纸蘸水能减少磨痕，提高涂层的平滑度，并且省砂纸、省力，但水磨后应注意喷涂下层油漆时，一是要等水磨层完全干透后才能涂下层油漆，否则漆层很容易泛白，另吸水性很强的底材也不宜水磨。

(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.

手板打磨时需要注意的问题：

Precautions for hand board polishing:

1.进行粗加工打磨选择一些很粗的砂纸，去掉表面很粗的毛刺之后再进行细纹的打磨，砂纸可以分为220，400，800，1000等等不同的等级，号越大砂纸越细，反之号越少砂纸就越粗。

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.

2.一般表面较为粗糙，需要通过砂磨获得较平整的表面，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.
