Frequently Asked Questions
Q: Which Raytools cutting head uses which ceramic model?
A: M11-D21.4-H16.3 for BT240/BT240S; M11-D21.4 (Three Hole) for BT240 high-speed cutting; M11-D32-H12 for BT210/BT220; M11-D41-H48.5 for BT300/BT440; 3D-M8-D19.5 for 3D-A/3D-B; 3D-M8-D21.4 for 3D-C/3D-D. If unsure, contact us with your cutting head model.
Q: What is the advantage of the three hole type ceramic ring?
A: The three hole type features an optimized airflow structure that provides more uniform protective gas output around the nozzle. This improves cutting stability, reduces slag adhesion, and delivers better cutting quality especially for high-speed cutting and thick plate cutting applications.
Q: What is the difference between 3D-M8-D19.5 and 3D-M8-D21.4?
A: The main difference is the outer diameter. 3D-M8-D19.5 is designed for older Raytools 3D-A and 3D-B robotic cutting heads, while 3D-M8-D21.4 is for newer 3D-C and 3D-D cutting heads. They are not interchangeable due to different dimensions.
Q: Can I use universal ceramic rings on my Raytools laser machine?
A: No, Raytools cutting heads use unique interface specifications and dimensions that differ from standard universal ceramic rings. Using universal ceramic rings on Raytools equipment will result in poor fit, air leakage, unstable height follow performance and potential damage to your cutting head.
Q: How often should I replace my Raytools ceramic ring?
A: Under normal operating conditions, a Raytools 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.
