手板模型要想做到跟成品接近，達到查驗出外觀的效果，就須制作一個手板模型。手板模型做好之后，首要就需要手板打磨，那么為什么要進行手板打磨呢？

If the prototype wants to be close to the finished product and achieve the effect of checking the appearance, it is necessary to make a prototype. After the prototype is completed, the first thing to do is to polish the prototype. So why should we polish the prototype?

濟南手板打磨便是底材外表上的毛刺，油污灰塵，降低工件外表的粗糙度，對舊漆層進行打磨后，還可增強涂層的附著力等等。手板打磨能夠分為傳統手工打磨和現代打磨。

Jinan hand sanding is to remove burrs and oil dust on the surface of the substrate, reduce the roughness of the surface of the workpiece, and enhance the adhesion of the coating after polishing the old paint layer. Manual grinding can be divided into traditional manual grinding and modern grinding.

由于一個手板零件在CNC加工后，它的表層無可避免的會發生許多的毛邊和刀痕。此刻就需要人為的手工進行處理這些問題。一般我們會選擇砂紙進行打磨，或進行拋光。

Since a hand made part is processed by CNC, many burrs and knife marks will inevitably occur on its surface. At this moment, people need to handle these problems manually. Generally, we will choose sandpaper for polishing or polishing.

常有的外觀處理有打磨，噴沙，拋光，上色，絲印，電鍍。手板打磨的工藝辦法一般能夠分：

Common appearance treatment includes polishing, sand blasting, polishing, coloring, silk screen printing and electroplating. Generally, the process methods of manual polishing can be divided into:

1.機械打磨：大面積施工時，為了進步工作效率。

1. Mechanical grinding: in order to improve the working efficiency during large-scale construction.

2.干打磨：采用砂紙進行打磨。進程中將發生許多粉塵，影響環境衛生。

2. Dry grinding: sand paper is used for grinding. A lot of dust will occur in the process, which will affect the environmental health.

3.濕打磨：用水砂紙蘸水或肥皂水打磨。水磨能削減磨痕，進步平滑度，并且省砂紙、省力。

3. Wet grinding: sand paper dipped in water or soapy water for grinding. Water grinding can reduce wear marks, improve smoothness, and save sandpaper and labor.

4.還有一種特殊的打磨辦法：“輕磨”，此刻應選用較細砂紙及熟手進行。

4. There is also a special grinding method: "light grinding", which should be carried out with fine sandpaper and skilled hands.

打磨的時分應該注意到問題，首要是需要粗打磨，去掉外表毛刺之后再進行細打磨，終根據產品對外表的要求進行打磨！

Attention should be paid to the problems when grinding. First, rough grinding is required. After removing the external burrs, fine grinding is carried out. Finally, grinding is carried out according to the product's requirements for the external appearance!

一次打磨完畢之后，通過噴上一層原子灰，能夠將產品外表的粗糙程度進行放大，肉眼能夠看到瑕疵的程度。終部分批改，直到一件產品終完成打磨進程。更多相關內容就來我們網站http://www.yigiba.com咨詢吧！

After one polishing, the roughness of the product surface can be magnified by spraying a layer of putty, and the degree of defects can be seen by the naked eye. The final part shall be corrected until a product is finally polished. More relevant content will come to our website http://www.yigiba.com Consult!
