OXIDE REMOVAL

What is laser oxide?

Oxide is formed during cutting processes such as laser, plasma or flame cutting. As long as there is oxygen as cutting gas, an oxide layer will form on the cut surface of the metal part.


Key Details About Laser Oxide:


  1. Cause: Primarily produced by or fiber laser cutting, when high-temperature areas interact with oxygen and air.

  2. Appearance: Usually a dark, powdery surface layer, commonly found on Stainless Steel and Aluminum components.

  3. Problems Caused: If left untreated, it causes weak, porous welds and leads to poor paint or coating adhesion (delamination).

  4. Removal Methods: Wide Belt grinding work, rotary brushing like ADV 508 RW or 508 RY  Series - Best Metal Surface Finishing  Solution.

  5. Applications: It is essential to remove this layer before painting,powder coating, or welding.

Q: Why remove laser oxide?


A: If there is oxide on the edge of your product, it will become very unstable for subsequent coating and painting processes. In addition, welding work will be difficult to carry out, and the weld will rust over time and even break. Therefore, removing oxide becomes very important.


Q: Is oxide the same as rust?


A: Rust is a specific type of oxidation that occurs when iron or its alloys react with oxygen and water, forming iron oxide (Fe₂O₃·nH₂O). So, all rust is oxidation, but not all oxidation is rust — for example, aluminum forms a protective oxide layer, not rust.



Laser oxide removal machines at ADV Grinding


In the past, we scraped off the oxide layer manually. Now ADV Grinding has 2 model steel wire brushes (W station and Y station) that can easily remove oxide from the surface and sides of the cut parts. You can find them below


W station

Y station

ADV 508-RY Series: When using steel wire abrasives at the Y station, the oxide on the cut surface can be easily removed. When changing the non-woven abrasives at the Y station, a uniform edge rounding effect can be obtained.


ADV 508-RW Series: Depending on the variety of abrasives, the W station can use sandpaper, steel wire abrasives, to achieve deburring, edge rounding, finishing and laser oxide removal of different metal parts.
