How to find the focus of a laser cutting machine?

1. Printing method: Move the cutting head from top to bottom and print the laser beam on the plastic board, with the minimum printing diameter as the focus.

2. Oblique plate method: horizontally pull a plastic plate at an angle to the vertical axis, and find the smallest part of the laser beam as the focal point.

3. Blue spark method: Remove the nozzle, blow air, and pulse laser on the stainless steel plate to move the cutting head from top to bottom until the blue spark reaches its maximum.

Currently, many manufacturers’ machines have achieved automatic focusing. Equipped with automatic focusing function, it can significantly improve the processing efficiency of laser cutting machines: the perforation time of thick plates is significantly shortened; When processing workpieces of different materials and thicknesses, the machine can automatically and quickly adjust the focus to the most suitable position.

4. Slant plate method: Use a plate placed at an angle to the vertical axis to pull horizontally and find the smallest part of the laser beam as the focal point.

5. Blue Spark Method: Remove the nozzle, blow air, and apply a pulse laser to the stainless steel plate, causing the cutting head to move from top to bottom until the blue spark reaches its maximum.

But with the progress of The New York Times, many manufacturers and machines have achieved automatic coking. Equipped with automatic coking function, it can significantly improve the processing efficiency of laser cutting machines: the perforation time of thick plates is significantly shortened; When processing workpieces of different materials and thicknesses, the machine can automatically and quickly adjust the focus to the most suitable position.
