在鋁卷的加工過程中，表面很容易出現劃痕，嚴重影響著鋁線圈的美觀度，劃痕多是因為加工不當造成的，我們在生產過程中可以用什么方法來避免劃痕出現？在發現有劃痕出現時又該如何處理呢？下面鋁卷加工廠家就分別為大家分享一下吧。
During the processing of aluminum coil, the surface is prone to scratches, which seriously affects the beauty of aluminum coil. Most of the scratches are caused by improper processing. What methods can we use to avoid scratches in the production process? What should I do when I find a scratch? Let's share with you the aluminum coil processing manufacturers.
避免劃痕的方法：
Methods to avoid scratches:
1、模具上的工作帶應打磨光滑，擠出模具的空刀應足夠光滑。
1. The working belt on the die shall be polished smooth, and the empty knife of the extrusion die shall be smooth enough.
2、CNC在加工過程中，還需要防止夾具上殘留的鋁渣劃傷卷材。
2. During the processing of CNC, it is also necessary to prevent the residual aluminum slag on the fixture from scratching the coil.
3、生產時，要注意模具線的生產，生成線后，應及時加載模具停止生產。
3. During production, pay attention to the production of the mold line. After the line is generated, the mold should be loaded in time to stop production.
4、鋸切過程中，每次鋸切后應及時清理鋸屑，防止二次刮擦，盡量避免卷材之間的相互摩擦。
4. During the sawing process, the sawdust shall be cleaned in time after each sawing to prevent secondary scraping and avoid mutual friction between coiled materials as much as possible.
5、在生產和搬運過程中，盡量不要拖動鋁卷。軌道或旋轉床上不能有夾雜物。
5. During production and handling, try not to drag the aluminum coil. There shall be no inclusions on the track or rotating bed.

劃痕處理方法：
Scratch treatment method:
1、化學方法：使用化學試劑進行拋光。就是用化學試劑腐蝕卷材的表面，特別是有鋒利邊緣的劃痕。化學拋光后，基本上可以消除較輕的劃痕。
1. Chemical method: polishing with chemical reagent. It is to use chemical reagents to corrode the surface of the coiled material, especially the scratches with sharp edges. After chemical polishing, light scratches can be basically eliminated.
2、物理方法：機械拋光、噴砂、拉絲等。這種方法多用于劃痕較深的情況。
2. Physical methods: mechanical polishing, sand blasting, wire drawing, etc. This method is often used in the case of deep scratches.
如果劃痕較重的話，可以將物理與化學方法結合起來使用，以達到更好的效果。
If the scratch is heavy, the physical and chemical methods can be combined to achieve better results.
