Laser Cutting Head BIMO-FSC

for Flexible Flat Sheet Cutting

The use of fiber lasers for cutting applications is growing steadily.
The design of HIGHYAG’s new BIMO-FSC cutting head takes all of the
special requirements of these lasers into account.

Maximum Productivity Applications
Productivity is key for flat sheet cutting machine Flat sheet cutting with high-brightness fiber, disc or diode
operators. The BIMO-FSC meets this need lasers; integration into 2D cutting machines
exactly. It has the capability to adjust the focus
position and focus diameter automatically via the Features
CNC. This allows for cutting of different sheet Modular optical system allows different options for focus
thicknesses without any manual intervention. In control, from simple to highly integrated:
