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
Productivity is key for flat sheet cutting machine operator, The BIMO-FSC meets this need exactly. It hasthe capability to adjust the focus position and focus diameter automatically via the CNC. This allows for cutting of different sheet thicknesses without any manual intervention. In combination with the BIMO-FSC's rapid focus movement on the work piece. efficient flat sheet cutting and maximum productivity are guaranteed.

Cutting Edge Quality
In addition, the cut quality is of particular importance. A determining factor of the cut quality is the optical design. The design of the BIMO-FSC allows for a reduction of the laser power-induced focus shift as well as for diffraction-limited imaging quality being the condition for best cut quality.

Flexible Machine Integration
The modular design enables the easy integration in dynamically moving flat sheet cutting machines. For optimized integration, the Cutting Head Controller(CHC) controls the motorized collimation, the capacitive height sensing and the cover slide monitoring, and it communicates via EtherCAT. In order to reduce the mechanical strain on the laser light cable system, the collimation module can be installed at the angel of 90°. Consequently, the BIMO-FSC can be integrated into any cutting machine.
