D31 M11 laser ceramic ring (ceramic insulator) , 31mm outer diameter , high-purity alumina ceramic , replacement consumable for fiber laser cutting head.

Material Introduction The main body is made of high-purity alumina ceramic, featuring excellent high-temperature resistance, stable electrical insulation and low thermal expansion coefficient. The embedded threaded seat adopts precision stainless steel, which ensures great coaxiality and smooth thread matching with fiber laser cutting heads. It delivers consistent height sensing performance during long-time continuous cutting work. Instructions Inspect the ceramic surface for
