在打磨的時候，需要用很粗的砂紙進行打磨，先把表面很粗的毛刺去掉之后再進行細紋打磨，砂紙可以分為800,1000,2000等等粗細不一的等級。

When grinding, first need to polish with very coarse sandpaper. First, remove the rough burrs before finishing the fine lines, and sandpaper can be divided into 80010002000 grades.

需要根據產品表面要求來選擇不同的砂紙來進行打磨。噴上一層原子灰，可以將產品表面的粗糙程度進行放大，可以用肉眼看到瑕疵的程度，然后進行局部的修正，直到一件產品完成打磨的過程！

Different sand paper should be selected according to the surface requirements of the product for grinding. Spraying a layer of atomic ash can enlarge the roughness of the surface of the product, and we can see the extent of the defect with the naked eye, then make partial correction until a product completes the grinding process.

打磨是手板制作過程中*基本的一個工藝，一個手板通過cnc數控機床加工之后，產品表面會有很多刀痕和毛刺，這是無法避免的，需要用手工來處理掉這些，一般我們是通過砂紙來打磨，或是拋光膏進行拋光,期間我們可以借助噴灰來檢測人工拋光的效果和質量。

Grinding is one of the most basic process board production process, a prototype by CNC CNC machining, the surface of the product will have a lot of marks and burr, which is unable to avoid, need to use hand to get rid of these, we are generally polished by sand paper, or polishing paste during polishing, we to test the effect and quality of manual polishing with ash.
