Corresponding wavelength: 1064/405nm

Equipment maintenance and calibration:
Ensure that laser cutting equipment is regularly maintained and calibrated to ensure that it operates within safe parameter ranges.

Work Area Restrictions:
Use safety barriers or other appropriate facilities to restrict unauthorized personnel from entering the work area and prevent unintentional exposure to laser radiation.

Emergency stop and emergency plan:
Design and implement emergency stop buttons and prepare emergency plans to respond to unexpected events such as laser leakage or equipment failure.

Ventilation and protective measures:
Ensure sufficient ventilation in the work area to prevent the impact of smoke, dust, and gases generated during laser cutting on operators.

Laser cutting materials

Stainless Steel

The advantages of stainless steel as a laser cutting material:

1.High precision
Laser cutting of stainless steel pipes is a high-precision processing method, with an accuracy of less than 0.1mm. This high-precision machining can not only meet the high precision requirements of component processing in industrial production, but also meet the needs of art, model making and other fields.

2.High efficiency
Compared to traditional processing methods, laser cutting of stainless steel pipes has higher processing efficiency. On the one hand, laser cutting equipment is easy to operate and can complete complex shape cutting in a short time; On the other hand, the power density of lasers is high, and high-power lasers can be used to cut stainless steel pipes of different thicknesses, greatly shortening the processing cycle and improving production efficiency.

3.Security
In the process of laser cutting, there is no need to fix the material, and there are no issues such as vibration and noise, avoiding safety hazards caused by vibration or noise in traditional processing.

Brands suitable for laser cutting
