What is the reason for indirect cutting of laser cutting machine

Laser cutting technology plays an important role in modern manufacturing. According to different application needs, many laser cutting machines have been launched in the market, which can be applied to different industries such as manufacturing, aviation, shipbuilding, advertising, etc. The number of application cases is also increasing. So what is the reason for the indirect cutting of laser cutting machines?

1. Mechanical system abnormality

Loose transmission components and loose X-axis belt can cause cutting trajectory deviation, and the tension needs to be checked regularly. When the guide rail deforms and the parallelism error of the guide rail exceeds 0.05mm/m, the deviation of the laser incidence angle is prone to intermittent cutting defects.

2. Process parameter imbalance

If the speed is too fast and exceeds the equipment's load threshold when cutting stainless steel, it will result in insufficient energy deposition. Focus deviation, if the focus deviates from the material surface by 0.1mm, it will cause energy dispersion. It is recommended to use focusing paper for calibration daily.

3. Material factors

Uneven thickness, for example, when the local thickness of a 3mm board reaches 4mm, the originally set power may not be able to penetrate thicker areas. Surface impurities, oxide layers, or rust can increase laser reflectivity and reduce energy absorption efficiency. If necessary, the material surface can be pre treated.

4. Laser power issue

Lens contamination, dust or oil stains on focusing mirrors and reflectors can hinder laser transmission and reduce energy density. For example, oil contamination can cause a 20% -30% loss of laser energy. Laser generator malfunction, aging, or component damage can cause output power fluctuations, and it is necessary to investigate voltage stability or whether the cooling system is normal.

What is the reason for the indirect cutting of laser cutting machines? It is recommended to prioritize checking the cleanliness and focal length parameters of the lenses during operation. After confirming that there are no abnormalities, the material status and transmission structure should be checked. Systematic elimination can improve diagnostic efficiency.
