BM111 3.3kW
High-performance Automatic Focusing Cutting Head
1. Multiple cover glass protection: total 3pcs protective lens to protect focusing and collimating lens
2. Excellent dustproof: IP65 class dustproof, patented protection cover glass catridge, ALL-body have anti-dust design
3. Auto-focusing: reducing human intervention, Max focusing speed 10/min, repeat accuracy 50μm
4. High-speed cutting: based on 3kW, cutting 12mm SUS304 at 0.6m/min, cutting 12mm Q235 at 1.2m/min
BM114 4/6kW
Economical Medium And High Power Automatic Focusing Cutting Head
1. High efficiency cooling: collimation and focusing lens are both cooled by water, air flow cooling is increased for nozzle, which can effectively protect the nozzle and ceramic, increase lifetime.
2. Auto-focusing: reducing human intervention, Max focusing speed 10/min, repeat accuracy 50μm
3. High-speed piercing and cutting: based on 3kW, pierces up to 25mm mild steel in 3 sec
4. Large clear aperture: 35mm clear aperture, effectively reducing stray light interference, guarantee cutting quality and lifetime.
5. Portable and durable: 5.6kg, compact structure, reduce the mechanical requirements.
6. High power rating: rate to 6.3kW, with D37 lens group, it’s easier to cut thick plate
BM115 6/8/12kW
High Power Automatic Focusing Cutting Head
1. High efficiency cooling: collimation and focusing lens are both cooled by water, air flow cooling is increased for nozzle, which can effectively protect the nozzle and ceramic, increase lifetime.
2. Fast zoom: using collimation to focus, compared focusing to focus, which moves faster with larger focusing range.
3. Large clear aperture: 35mm/36.1mm clear aperture, effectively reducing stray light interference, guarantee cutting quality and lifetime.
4. Excellent design: the integrated body design ensures to seal completely. Improvement of QBH QD Q+ fiber interface improves the compatibility of the laser source. Don’t get stuck due to water leakage, rust, etc any longer.
5. High power rating: rate to 12kW, with D37/D38 lens group, it’s easier to cut thicker plate
