Application
The BM06K cutting head is used for flat sheet fiber laser cutting systems where automatic focus control is required. It is suitable for machines operating in medium-power cutting applications up to 6 kW.
The head supports focus adjustment for different cutting conditions and material thicknesses. Correct configuration depends on the machine, laser source, CNC system, height control system, assist gas supply and selected optical setup.
Protection and Monitoring
The BM06K 2D Series manual specifies temperature monitoring for the bottom cover glass and dual cover glass protection for the collimation lens. These functions help monitor the condition of key optical protection components during operation.
The manual also indicates smart monitoring compatibility with Android, which may be used depending on the machine configuration and control setup.
Service and Consumables
The BM06K cutting head uses replaceable optical and mechanical consumables, including nozzles, ceramic bodies, cover glasses, lenses, seals, cables and related service components.
When ordering consumables or spare parts for BM06K, it is important to check the exact head model, optical configuration, fiber interface, nozzle type, protective window size and machine compatibility. Similar-looking parts may have different dimensions, installation geometry or technical specifications.
