Laser cutting machine cutting FAQ

1.what is the reason for the pollution of the protective mirror?

First of all, we must determine the types of pollutants, pollutants usually have waste residue, oil stains, dust, water mist and mixtures.

1.Waste residue: mainly due to improper parameter setting, resulting in cutting waste splash on the lens. It can be solved by adjusting the process parameters of cutting or punching, such as follow-up height, cutting pressure, laser pulse parameters, etc.

2.Oil stains or dust: the auxiliary gas itself or the gas flow pipeline is polluted. Oil or dust can be controlled by adding a filter.

3.Water mist: Generally caused by excessive temperature difference. The ambient temperature is too high, the cutting gas temperature is too low, the protective mirror is formed by condensation in the ambient temperature, and the temperature of the two can be adjusted appropriately to make it similar to solve.

2.how to deal with the heat of cutting carbon steel plate cutting nozzle, what is the cause?

As the laser power increases, in order to pursue speed and cross-section brightness, thick plates also begin to use high-power vaporization cutting, and small nozzles need to be matched

Cutting carbon steel heating reasons:

1.cutting gas flow is small, can not fully cool the copper nozzle. High-pressure nitrogen can be used as an auxiliary gas, and high-pressure nitrogen has a good cooling effect.

2.no copper nozzle cooling gas. The cooling gas of copper nozzle can reduce the heat of copper nozzle.

3.high focus cutting, the laser is easy to hit the small nozzle, so that the nozzle overheating. It is necessary to adjust the focus or increase the nozzle diameter when the nozzle is not hot.

4.When carbon steel is cut, oxidation occurs and a lot of heat is generated. This situation cannot be avoided, and the distance between the nozzle and the material can be properly adjusted.
