BM114S series are auto focusing cutting head, BM114S comes with the builtin motor and drive unit through the linear driver and the focusing lens can automatically change the position in the range of 25mm. The user can set the focus continuously through the program to complete the rapid perpiercing of thick sheets or other different thickness and material sheets. The product can be equipped with large clear aperture lens group to integrate the light beam. The heads have diversification interface settings that allow with a variety of fiber lasers. The optimization of optical design and the design of water-cooled allows laser heads stably and chronically to work at high power lasers.

• Rated to 6KW optical power at 1μm , with D37 lens group ,  and more strength to cut thick plate； • Auto focus ranges +10~-14mm, accuracy is 0.05mm; • Maximum acceleration of focus lens drive is 10m/s2, maximum speed is 10m/min; • Collimation and focusing lenses are both water cooled. Increase air flow cooling for nozzle , effectively protect the nozzle and ceramic body and the lifetime； • 35mm clear aperture, effectively reducing stray light interference, guarantee cutting quality and service life； • 5.6KG，compact structure, reduce the mechanical requirement；
