M11 x D28 Fibre Laser Ceramic Ring — Raytools, Precitec, WSX, Han's, BOCI, Bodor Fit
Replacement 28 mm ceramic ring for fibre laser cutting heads that run M11 nozzles.
The ceramic ring (also called the ceramic nozzle holder or ceramic body) holds your nozzle on the cutting head and insulates it, so the capacitive height sensor reads cleanly. A cracked or chipped ring causes height-following errors, nozzle crashes and poor cut quality. Check it regularly and after any head crash. Many shops replace them around every 150 hours of cutting.
