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.

　　半精拋:主要使用砂紙和潤滑劑。砂輪加工后，用砂紙去除砂輪加工后的疏漏，使拋光體整體表面的磨削痕跡更細、更小、更均勻。具體拋光時，旋轉體應與砂輪方向一致，手板的拋光方向應與砂輪方向交叉。

　　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.

　　精拋:主要采用金剛石研磨膏。金剛石研磨粉或研磨膏與拋光布輪混合，通常是小到大的訂單。金剛石研磨膏和拋光布輪用于去除砂紙留下的毛發(fā)狀磨痕。精度要求在1米以上的拋光工藝可以在加工車間的潔凈拋光室進行，如果更精密的拋光必須是潔凈的空間，因為灰塵、煙霧、頭皮屑和唾液都可能使表面經過高精度拋光后產生報廢。

　　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. 砂輪加工后用砂紙去除遺漏，使拋光體整體表面磨痕更細更小，平衡一致。具體的甩動，旋轉體應與砂輪甩動方向一致，手板甩動方向應與砂輪甩動方向交叉。2. 使用砂輪和少量的綠藥膏去除砂輪加工后的劃痕,這樣彈丸的身體似乎肉眼沒有明顯的劃痕,表面是平衡和一致的,觸摸的手有一種柔軟的感覺。3.在砂輪上均勻涂抹少量綠色軟膏，進一步砂輪留下的小痕跡，使彈丸上不易出現(xiàn)劃痕。

　　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.

　　鏡面光處理:先用麻花輪加白藥膏處理，使彈丸表面有一種暗光，用布輪敲打，達到鏡面效果。當布輪鞭子,它應該充滿油,這輪有一個軟的感覺,力量不應太大鞭打時,為了不使身體改變顏色,與此同時,在攪拌的過程中經常檢查車輪,適當的安排長羊毛布,線長,這樣布輪平的。

　　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.

　　亞光處理:在個四個步驟來處理一樣的鏡光處理,即添加細Ⅲ處理后,使用亞光處理。

　　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.
