  Laser cutting machine after cutting black how to go?After the laser cutting machine cuts the metal, whether we have the phenomenon of blackening the surface or edge?得马Tell you, this is mainly caused by the high temperature and oxidation caused by laser cutting, more specific reasons we will talk about it in detail。

  Laser cutting machine after cutting black how to go?

  1, surface treatment: the treatment method of the material surface will also affect the result of laser cutting。For example, if there are impurities such as oil and flash on the surface, they will be baked to form coke when the laser cuts, resulting in black spots on the surface。

  2, material composition: An important factor leading to laser cutting black is the composition of the material。When the laser energy is absorbed, most of the energy is converted into heat, if the material composition contains easily oxidized materials, such as iron, steel and other metals, or wood containing cellulose, it will produce oxidation reaction, resulting in black spots on the surface。

  Laser cutting machine after cutting black how to do?

  1, improve the material surface treatment method: before laser cutting, the surface of the material is properly treated, which can effectively avoid black spots on the surface of the material。For example, the use of treatment measures such as oil removal and flash removal can make the surface of the material smoother, thereby avoiding the generation of black spots。

  2, reduce the laser power: if the laser power is too high, it will lead to too much heat on the surface of the material, which causes the oxidation reaction of the material, resulting in black spots on the surface。Therefore, the appropriate reduction of laser power is one of the important means to avoid blackening。

  Through the above method, the phenomenon of laser blackening can be improved。

  Laser cutting machine after cutting is not smooth how to go, how to do?

  1, material problems: the type and state of the material has a great impact on the cutting effect。For example, hard and brittle materials (such as stainless steel, copper, aluminum) or materials with oily surfaces may be more difficult to cut, which can result in uneven or non-smooth cutting surfaces。

  2, focus offset: focus is an important part of laser cutting quality。If the optical path or lens of the laser cutting machine is improperly adjusted, the focus will be offset, which will affect the smoothness of the cutting surface。

  3, cutting speed: different materials need to match different cutting speeds。If the cutting speed is not set properly, it may cause the material to partially melt and be insufficient, or the material surface to burn during rapid cutting, which may affect the quality of the cutting surface。

  4, equipment problems: including the instability of the laser output power and the inconsistent depth of the weld groove in the laser cutting process。These problems need to be solved through the inspection and adjustment of the equipment。

  5, process problems: such as laser cutting speed is too fast, gas flow is too large or too small, tool wear, etc., which may lead to the cutting surface is not smooth。

  6, laser beam position deviation: in the cutting process, if the position of the laser beam has changed, it may lead to the workpiece is not completely cut, resulting in an unsmooth section。This situation can be solved by re-adjusting the beam position of the laser cutting machine。

  7, the purity of the auxiliary gas is insufficient: if the purity of the auxiliary gas used is not high, it may also lead to the cutting surface is not smooth。In this case, you should consider replacing the gas with a higher purity。

  To sum up, in order to improve the problem that the cutting surface of the laser cutting machine is not smooth, it is necessary to check and adjust according to the above various situations to ensure the best cutting conditions。
