The best way to remove the oxide layer on the cutting surface

Any oxygen cutting process, whether flame or laser, will leave an oxide layer on the cutting edge. The oxide layer has characteristics different from the material of the part itself, which will seriously affect the subsequent processing. Therefore, it is necessary to remove the oxide layer.

In general, cutting processes using nitrogen or argon do not have an oxide layer problem. But when you cut with oxygen, the material at the incision burns and creates residue. In the process of thermal cutting, the oxide layer will appear on the cutting surface. In the case of steel parts, the oxide can be peeled off with light force. However, if the oxide layer stubbornly remains on the surface of the workpiece, the subsequent coating will cause rapid peeling of the protective coating; Moreover, the welding process will not last long or its effect will not be uniform. In this case, the rust on the one hand and can not be collected, serious directly lead to the finished products fall apart. In addition, the oxide skin also greatly affects the visual appearance of the product.

In general, the oxide layer on the cut surface can be easily removed by sandblasting, especially for thick plates. Pickling is also an option for removing the oxide layer if appropriate equipment and chemicals are available.

The main grinding tools of the deburring machine for processing sheet metal are roller brush, brush plate or brush block. They can be used to round the edges of sheet metal pieces or to remove the oxide layer on the cutting surface. Oxide removal tools are equipped with special pins whose fine tips remove the oxide and cause it to fall off the cutting surface. The roller brush and brush plate are only single-sided processing, so it is necessary to turn the parts after the second time through the machine to deal with the oxide layer. And in a one-sided machine, the parts need to be fixed by vacuum. And the grinding brush block can be double-sided processing, do not need to flip parts can achieve efficient grinding.

In any case, deburring machines are superior to manual operation - this is reflected in the reliability and stability of processing quality and accuracy. Because these machine systems work much faster than manual labor using files or Angle mills, processors can quickly recoup their investment costs.

However, all processes have one thing in common: the grinding tool affects the surface appearance of the part. Therefore, the quality of the surface of the parts is another criterion for selecting the process.

The burr brush can also remove the oxide layer

No matter which machine is used, the task of removing the oxide layer on the cutting surface is the grinding brush. Depending on the deburr machine, a specialized oxide removal brush can be used. Depending on the alloy, sheet metal manufacturers can use it to treat sediments that are harder to remove. In this way, the processed sheet metal parts can obtain a perfect surface edge.

The ultimate goal of sheet metal processors is to provide customers with the quality parts they want. Especially for finished products for outdoor use, no manufacturer can tolerate the slightest neglect of coating quality, otherwise the product will lose its durability. Therefore, the removal of oxide layer and edge rounding is an essential process.

Whether the use of a deburring machine to remove oxide is the right choice, and whether another method is more suitable, depends entirely on the requirements of the production. Through the test and comparison of various processes, users can have a good understanding of the performance of deburring machine to remove oxide and processing effect.
