Ceramic Ring Product Info
-
High-quality ceramic with special alloy insert
Precision-machined for a tight fit and smooth gas seal. The alloy center improves conductivity and durability, with typical service life rated for hundreds of hours of cutting under normal conditions.
-
Electrical insulation for stable height sensing
Ceramic barrier isolates the nozzle from the laser head, preventing shorts and signal interference. This stability helps maintain accurate focus control even at assist gas pressures up to 25 bar.
-
Heat- and spatter-resistant protection
Withstands rapid temperature swings and resists molten metal splash, protecting the head assembly. Proper sealing preserves gas flow, reducing dross and extending nozzle/consumable life.
