Frequently Asked Questions

Q: Which Han's Laser cutting heads use this ceramic ring?
A: This M11-D40.8-H34 ceramic ring is compatible with most mainstream Han's Laser fiber laser cutting heads, including the HAN'S 3000, HAN'S 6000, HAN'S 12000 and HAN'S 20000 series cutting heads. It is also compatible with Han's Laser G3015, G4020 and G6020 series cutting machines. If you are unsure about compatibility, please contact our sales team with your cutting head model number for confirmation.

Q: Can I use universal ceramic rings on my Han's Laser machine?
A: No, Han's Laser cutting heads use unique interface specifications and dimensions that differ from standard universal ceramic rings. Using universal ceramic rings on Han's Laser equipment will result in poor fit, air leakage, unstable height follow performance and potential damage to your cutting head.

Q: What is the advantage of 99% alumina ceramic over lower purity materials?
A: 99% high-purity alumina ceramic offers superior mechanical strength, better thermal shock resistance and more stable electrical insulation properties compared to lower purity materials. It is less likely to crack under high-power laser cutting conditions and provides longer service life, especially in thick plate cutting applications.

Q: How often should I replace my Han's Laser ceramic ring?
A: Under normal operating conditions, a Han's Laser ceramic ring should last 2-3 months. However, it should be replaced immediately if you notice any cracks, chips, or if the height follow system becomes unstable. Frequent collisions between the nozzle and workpiece will significantly shorten its service life.

Q: Do you offer other Han's Laser ceramic ring models?
A: Yes, we can provide custom sizes and special models for all Han's Laser cutting heads upon request. Please contact our sales team with your specific requirements and we will be happy to assist you.
