在铝卷的加工过程中，表面很容易出现划痕，严重影响着铝线圈的美观度，划痕多是因为加工不当造成的，我们在生产过程中可以用什么方法来避免划痕出现？在发现有划痕出现时又该如何处理呢？下面铝卷加工厂家就分别为大家分享一下吧。
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.
避免划痕的方法：
Methods to avoid scratches:
1、模具上的工作带应打磨光滑，挤出模具的空刀应足够光滑。
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在加工过程中，还需要防止夹具上残留的铝渣划伤卷材。
2. During the processing of CNC, it is also necessary to prevent the residual aluminum slag on the fixture from scratching the coil.
3、生产时，要注意模具线的生产，生成线后，应及时加载模具停止生产。
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、锯切过程中，每次锯切后应及时清理锯屑，防止二次刮擦，尽量避免卷材之间的相互摩擦。
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、在生产和搬运过程中，尽量不要拖动铝卷。轨道或旋转床上不能有夹杂物。
5. During production and handling, try not to drag the aluminum coil. There shall be no inclusions on the track or rotating bed.

划痕处理方法：
Scratch treatment method:
1、化学方法：使用化学试剂进行抛光。就是用化学试剂腐蚀卷材的表面，特别是有锋利边缘的划痕。化学抛光后，基本上可以消除较轻的划痕。
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：机械抛光、喷砂、拉丝等。这种方法多用于划痕较深的情况。
2. Physical methods: mechanical polishing, sand blasting, wire drawing, etc. This method is often used in the case of deep scratches.
如果划痕较重的话，可以将物理与化学方法结合起来使用，以达到更好的效果。
If the scratch is heavy, the physical and chemical methods can be combined to achieve better results.
