Shandong rapid prototyping personnel's analysis of the model, the grinding of the hand plate is an important process that the hand plate must go through in the manufacturing process. After the parts are processed on CNC machine tools, there will be many burrs and knife marks on their surfaces. During this period, the quality and effect of artificial polishing can be tested by some methods of ash spraying.

　　該模型的手版可分為形狀和結構的磨削，這里濟南手版為我們介紹了彩色表面加工要求的手版的外觀。

　　The hand plate of the model can be divided into shape and structure grinding. Here Jinan hand plate introduces the appearance of the hand plate required by color surface processing.

　　普通手板，要求表面的處理與產品相似，這樣才能徹底檢查出外觀的效果。在研磨時，要用很厚的砂紙把它稍微研磨一下。在進行詳細的磨削之前，要先去除表面的粗邊。

　　Ordinary handboards require surface treatment similar to products, so as to thoroughly check the appearance effect. When grinding, first use a thick sandpaper to grind it slightly. Before detailed grinding, the rough edge of the surface shall be removed.

　　根據要求對手板表面進行不同程度的磨削，經過一次磨削后，通過噴涂膩子，使手板表面的粗糙度擴大。這樣眼睛就能看到缺陷。然后，有可能在計劃的基礎上進行部分分級，直到一個面板更終完成整個磨削過程。

　　According to the requirements, the surface of the hand board is grinded in different degrees. After one grinding, the surface roughness of the hand board is enlarged by spraying putty. So that the eye can see the defect. It is then possible to partially grade on a planned basis until one panel has finally completed the entire grinding process.

　　濟南手盤與我們共享的手盤磨削過程主要有以下三個作用:

　　The grinding process of Jinan handdisc and our shared handdisc mainly has the following three functions:

　　1. 關于基材，主要是去除基材表面的毛刺和油灰;

　　1. For the base material, it is mainly to remove the burr and putty on the surface of the base material;

　　2. 于刮膩子的外觀，一般外觀比較粗糙。要求通過砂光處理獲得相對平整的外觀，這樣的磨削效果可以降低工件表面的粗糙度;

　　2. The appearance of puttying is generally rough. It is required to obtain a relatively flat appearance through sanding, so that the grinding effect can reduce the surface roughness of the workpiece;

　　3.增強涂層的附著力。在噴涂新漆膜之前，一般有必要對舊漆膜進行打磨后的工作，因為涂層在過度光滑的外觀附著力較差，打磨后可以增強涂層的機械附著力。

　　3. Enhance the adhesion of the coating. Before spraying the new paint film, it is generally necessary to polish the old paint film, because the adhesion of the coating on the excessively smooth appearance is poor, and the mechanical adhesion of the coating can be enhanced after polishing.
