A CO2 laser marking machine with a rotating axis is designed to mark or engrave cylindrical or round objects with high precision. The rotating axis (also called a rotary attachment or rotary axis) allows the laser to work on curved surfaces by rotating the object while the laser head moves linearly, ensuring consistent marking around the circumference.
How It Works:
Laser Source (CO2 Laser Tube)
The CO2 laser generates an infrared beam (wavelength ~10.6 µm) ideal for marking organic materials (wood, acrylic, leather, glass, plastics, etc.).
Galvo Scanning System or XY Motion System
Galvo-based: Uses mirrors to direct the laser beam at high speed (best for flat or slightly curved surfaces).
XY Gantry: Moves the laser head in X and Y directions (better for larger cylindrical objects).
Rotating Axis (Rotary Attachment)
A motorized chuck or roller system holds and rotates the workpiece (e.g., bottles, tubes, rods).
Synchronizes rotation with laser movement to ensure even marking.
Can be 3D rotary for complex curved objects.
Control Software
Converts vector/bitmap designs into laser paths.
Adjusts rotation speed and laser firing for distortion-free marking.
Key Applications:
Bottles & Containers (Glass, plastic)
Pipes & Tubes (Metal, PVC)
Pens & Cylindrical Parts
Rolling Labels & Packaging
Advantages:
✔ 360° Marking – Seamless engraving on round objects.
✔ High Precision – No distortion, even at high speeds.
✔ Automation-Friendly – Works with conveyor systems for mass production.
Considerations:
Object Size: Must match the rotary chuck’s diameter capacity.
Material Compatibility: CO2 lasers work best on non-metals; fiber lasers are better for metals.
Speed vs. Resolution: Faster rotation may reduce detail.
