Raytools Ceramic Ring D32-H12.2-M14 For Laser Cut Head

✅ Made from a 95% high-purity alumina ceramic substrate, it offers high-temperature resistance and thermal shock resistance, and is less prone to chipping or cracking under conditions of blowholes and spatter.
Precision machining ensures high coaxiality and end-face flatness, resulting in excellent optical path concentricity after nozzle assembly, a stable cutting spot, and reduced issues with skewed cuts and poor cut surfaces.
✅ Features built-in high-quality capacitive metal contacts that ensure sensitive and stable signal transmission, effectively reducing the failure rate of alarms caused by abnormal nozzle height or loss of tracking control.
✅ Direct replacement requires no modification to the cutting head; easy installation and removal minimize downtime for debugging.
✅ Excellent insulation properties effectively resist arcing during piercing, reducing the likelihood of ceramic ablation damage and extending service life.
✅ The ceramic body has a dense, smooth surface that prevents slag from adhering, making cleanup simple and reducing the workload of daily maintenance.
