Bochu Original Nozzle Cooling Ceramic M16×1 BLT643

✅ Integrated recirculating water cooling
Prevents heat buildup, avoids ceramic burnout, thermal deformation, and capacitor signal drift; suitable for high-power continuous machining with the BLT643H
✅ 2–3 times longer service life, reducing downtime losses
Water-cooled temperature control resists arcing and slag adhesion, lowering costs for replacement parts and minimizing downtime for part replacement
✅ Stable tracking signal, supporting unmanned cutting
Metal sensing contacts maintain consistent resistance even at high temperatures, minimizing errors during prolonged processing of thick plates
✅ 95% alumina ceramic, high-temperature and impact-resistant
Withstands instantaneous temperatures up to 1200°C; resists thermal shock; provides insulation against arc breakdown; resistant to chipping and internal cracking
✅ Micrometer-level precision machining, superior cutting quality
M16×1 thread ensures minimal spot offset; thick plate cut surfaces exhibit minimal jagged edges and low slag adhesion
✅ Leak-proof design to protect optical components
Eliminates water-cooling leaks and prevents coolant contamination, safeguarding lenses and internal optical components
✅ Original Baochu parts, quick installation and easy maintenance
Compatible with BLT643H; pairs with DP.M.Q0393AA locking ring for direct installation without modification; modular design allows ceramic replacement in 5 minutes, compatible with equipment ≤15 kW
✅ Compatible with automated production lines, reducing overall consumable costs
Reduces nozzle oxidation and loosening; the ceramic is slag-resistant and easy to wipe clean, making it suitable for automated loading/unloading in batch production
