CO2 laser cutting three-mirror optical path cross calibration target 21mm round hole

This is a high-precision optical path and perpendicularity calibration tool specifically designed for non-metal CO2 laser cutting machines, perfectly solving the pain points of optical path deviation and inaccurate perpendicularity in daily equipment maintenance.

The tool is 3D printed, achieving precise visual positioning of the laser spot through a combined design of cross copper wire positioning + high-temperature masking tape target:

1. Optical Path Calibration: The crisscrossing copper wires will be instantly ablated by the laser, forming a clear "cross-shaped burn mark" on the target paper, helping you quickly determine if the laser beam passes through the center of the optical path, and easily adjust the mirrors to ensure laser path coaxiality.
2. Perpendicularity Calibration: Fix the tool below the laser head; the relative position of the burn mark on the target paper and the copper wire cross after ablation can intuitively reflect the perpendicularity deviation between the laser head and the workbench. After calibration, cutting accuracy can be significantly improved, avoiding problems such as "slanted edges" or "incomplete cuts."

After actual testing, the laser spot focusing effect is excellent, and the perpendicularity error is controlled within a very small range. When cutting materials like acrylic and wood, the cutting surface perpendicularity and edge smoothness have been qualitatively improved.

The tool is easy to install and convenient to operate, requiring no complex equipment, making it a practical artifact for laser machine users for daily maintenance and improving processing accuracy.
