BM111 SERIES 3KW Auto-Focusing Laser Cutting Heads User Manual
4 | 28
1 Introduction
This manual includes the general description, basic installation, factory settings, operation and
maintenance services and other aspects of BM111 series products, which have too many optical
and mechanical customization configurations, so only the main parts will be introduced in this
manual.
The BM111 series laser heads are auto-focusing cutting heads for fiber laser, which are
released by Switzerland RAYTOOLS AG in 2017. The products are equipped with internal servo
motor drive units, which use the linear mechanism to drive the focusing lens to change position in
the range of about 22mm automatically. Users can use the program settings to achieve continuous
adjustment of the focus position to complete the rapid perforation of thick plates and automatic
cutting of different thickness, material plates. The products can be equipped with D30 composite
lens groups to integrate the beam. Diversified interface configurations can be adapted to a variety
of fiber lasers, optimized optical and water-cooled design allows the laser heads work under high
power for a long time continuously and steadily.
