Features

The BM109 was introduced by Swiss company RAYTOOLS AG in 2017, according to the source. An external servo motor and internal controller move the focusing lens through a linear mechanism over an approximately 17 mm range. Programmed focus changes can support piercing thick plate and cutting different materials and thicknesses; confirm settings with the machine maker.

Modular construction is described as easier to maintain.
Two water-cooling circuits are listed.
Automatic focusing is intended to reduce manual intervention and support cutting and piercing efficiency.
Three protective windows (upper, middle and lower) protect the focusing and collimating lenses.
The source describes a patented dust-resistant cutting head rated IP65.
