Blank: you can choose to use a polishing machine for polishing. The commonly used method is to remove the burr, small sand pit and small scratch on the handboard model with the grinding wheel. There are two specifications of the grinding wheel: the 400mm grinding wheel is suitable for the rotating body, and the 300mm grinding wheel is suitable for the handboard. After rough grinding, use oilstone for grinding, with oilstone and lubricant or coolant.

　　半精抛:主要使用砂纸和润滑剂。砂轮加工后，用砂纸去除砂轮加工后的疏漏，使抛光体整体表面的磨削痕迹更细、更小、更均匀。具体抛光时，旋转体应与砂轮方向一致，手板的抛光方向应与砂轮方向交叉。

　　Semi fine polishing: mainly using sandpaper and lubricant. After the grinding wheel is processed, the omission after the grinding wheel is removed with abrasive paper, so that the grinding trace on the whole surface of the polishing body is finer, smaller and more uniform. When polishing, the rotating body shall be in the same direction as the grinding wheel, and the polishing direction of the handboard shall be crossed with the grinding wheel direction.

　　精抛:主要采用金刚石研磨膏。金刚石研磨粉或研磨膏与抛光布轮混合，通常是小到大的订单。金刚石研磨膏和抛光布轮用于去除砂纸留下的毛发状磨痕。精度要求在1米以上的抛光工艺可以在加工车间的洁净抛光室进行，如果更精密的抛光必须是洁净的空间，因为灰尘、烟雾、头皮屑和唾液都可能使表面经过高精度抛光后产生报废。

　　Fine polishing: mainly using diamond grinding paste. Diamond grinding powder or paste is mixed with polishing cloth wheel, usually small to large order. Diamond paste and polishing cloth wheel are used to remove the hair like abrasion marks left by sandpaper. The polishing process with a precision requirement of more than 1 meter can be carried out in the clean polishing room of the processing workshop. If the polishing is more precise, it must be an absolutely clean space, because dust, smoke, dandruff and saliva may cause the surface to be scrapped after high precision polishing.

　　1. 砂轮加工后用砂纸去除遗漏，使抛光体整体表面磨痕更细更小，平衡一致。具体的甩动，旋转体应与砂轮甩动方向一致，手板甩动方向应与砂轮甩动方向交叉。2. 使用砂轮和少量的绿药膏去除砂轮加工后的划痕,这样弹丸的身体似乎肉眼没有明显的划痕,表面是平衡和一致的,触摸的手有一种柔软的感觉。3.在砂轮上均匀涂抹少量绿色软膏，进一步砂轮留下的小痕迹，使弹丸上不易出现划痕。

　　1. After the grinding wheel is processed, the omission shall be removed with sandpaper, so that the grinding mark on the whole surface of the polishing body is finer and smaller, and the balance is consistent. For the specific swing, the rotating body shall be in the same swing direction as the grinding wheel, and the swing direction of the handboard shall cross the swing direction of the grinding wheel. 2. Use the grinding wheel and a small amount of green ointment to remove the scratches after the grinding wheel processing, so that the body of the projectile does not seem to have obvious scratches with the naked eye, the surface is balanced and consistent, and the touch hand has a soft feeling. 3. Evenly apply a small amount of green ointment on the grinding wheel to further eliminate the small traces left by the grinding wheel, so as to prevent scratches on the projectile.

　　镜面光处理:先用麻花轮加白药膏处理，使弹丸表面有一种暗光，用布轮敲打，达到镜面效果。当布轮鞭子,它应该充满油,这轮有一个软的感觉,力量不应太大鞭打时,为了不使身体改变颜色,与此同时,在搅拌的过程中经常检查车轮,适当的安排长羊毛布,线长,这样布轮平的。

　　Mirror light treatment: first use twist wheel and white ointment treatment to make the surface of the projectile have a dark light, and finally use cloth wheel to knock to achieve the mirror effect. When the cloth wheel whips, it should be full of oil. This wheel has a soft feeling. When the power is not too large, in order not to change the color of the body, at the same time, the wheels should be checked frequently during the mixing process, and the long wool cloth should be arranged properly, with long thread, so that the cloth wheel is flat.

　　亚光处理:在个四个步骤来处理一样的镜光处理,即添加细Ⅲ处理后,使用亚光处理。

　　Matte treatment: in the first four steps to deal with the same mirror light treatment, that is, after adding the fine III treatment, use the matte treatment.
