Laser Cutting Head BIMO-FSC
Defining Cutting Edge Quality

High productivity and high cut quality are essential criteria for flat sheet cutting. These criteria have been the basis for the II-VI HIGHYAG laser cutting head BIMO-FSC.

The BIMO-FSC is available in different variants for focus control. Depending on the cutting application, the customer can choose to control the focus position and focus diameter using the cutting machine or to utilize the simple manual control. Maximum productivity in manufacturing can be achieved by usage of the BIMO-FSC with machine controlled adjustment of focus position and focus diameter. This enables flexible cutting of various sheet thicknesses without manual intervention and hence guarantees highest productivity in manufacturing.

A particular advantage of the BIMO-FSC is its excellent cut quality. The laser-power induced focus shift is minimal and the imaging quality is diffraction-limited. Other important criteria for flat sheet cutting machine operators are lifetime and maintenance of the components. A long lifetime of the BIMO-FSC is ensured by an advanced mechanical sealing which prevents contamination of the optics. The cover slide under the focusing lens is fitted with a special drawer which enables user-friendly replacement.

For optimized integration in dynamically moving flat sheet cutting machines, the Cutting Head Controller (CHC) controls the motorized collimation, the capacitive height sensing and the cover slide monitoring, and it communicates via EtherCAT.
