Laser cutting machine focus debugging skills
Focus position adjustment method*:
1. Printing method: Move the cutting head up and down, and the laser beam is printed on the plastic plate. The focus position is where the print diameter is the smallest.
2. Inclined plate method: Use an inclined plate at a certain angle to the vertical axis to pull horizontally to find the minimum point of the laser beam, which is the focus position.
3. Blue spark method: Remove the nozzle, blow air, and hit the pulse laser on the stainless steel plate, so that the cutting head moves up and down until a blue spark appears. This position is the focus.
Focus brightness and dimming method*:
The adjustment of focus brightness and light is usually related to factors such as laser power, lens status, and gas pressure. Ensure that the lens is clean and pollution-free, and adjust the laser power and gas pressure appropriately to improve the focus brightness and cutting effect.
Precautions*:
When adjusting the focus, be careful and serious to avoid the cutting head from bumping down and causing damage.
The lens temperature should be controlled well, and overheating will affect the cutting effect.
Before changing the lens, make sure your hands are clean, free of dust and impurities to avoid affecting the transmission and quality of the laser.
In summary, although there is no specific formula, following the above methods and precautions can effectively debug the focus of the laser cutting machine.
