    4kW 3D Robotic Laser Cutting Head

    Auto focus laser cutting head with built-in follower axis for cutting complex 3D shapes

    A common challenge in robotic 3D cutting is to keep the nozzle-to-part distance steady as the path moves over curves and formed sections, while focus adapts to local thickness changes. Our 4 kW 3D robotic laser cutting heads address this with auto focus and a built-in height follower (capacitive standoff control). These features hold the standoff constant on contoured panels and keep cut quality stable as the robot changes angle and speed. The body is compact and well-sealed, so it fits tight robot workspaces. A precise reset mechanism and an anti-collision design protect alignment after minor bumps, which helps production stay consistent.

    Features
    QBH water-cooled fiber input for steady operation
    QBH water-cooled fiber input for steady operation

    Closed-loop water cooling at the QBH interface/connector keeps temperature stable and prevents condensation on the optics, so long runs remain consistent.

    Precision reset locating
    Precision reset locating

    A three-point conical locating system returns the head to its original position after a bump, so alignment stays accurate.

    Sealed built-in height follower with fast response

    The integrated follower module (capacitive standoff control) is fully enclosed and lightweight, keeping dust out while tracking surfaces quickly for precise, high-speed cutting.

    Triple protective-window stack for optics protection
    Triple protective-window stack for optics protection

    Three protective windows shield the core focusing optics from spatter and dust, improving durability in daily production.

    Anti-collision protection with stop signal
    Anti-collision protection with stop signal

    A compliant sensor mount uses shear screws (designed to break safely on impact) to protect the head and simultaneously send a collision stop signal to the controller.

    Collision emergency stop for safe production

    They’re intended for thin-sheet work across a broad range of jobs: signage and display parts, small metal fittings and brackets, electrical enclosures and cabinet panels, elevator panels, and thin components in aerospace and automotive (for example, trim pieces and small formed parts). They also suit short, custom runs that need clean edges and stable dimensions.

    The main assemblies use an integrated housing that improves sealing and durability, protecting the optics and extending service life. On the control side, the heads connect to plant CNC/smart control for remote status monitoring with real-time alerts and diagnostics. When readings drift, the system warns operators early to prevent faults, cut unplanned downtime, and avoid extra costs for parts or on-site service. Remote diagnostics speed up root-cause identification, reduce back-and-forth in after-sales support, and improve service efficiency.

    Low-power heads target thin-gauge metals such as carbon steel, stainless steel, and aluminum. As a rule of thumb, thickness is up to about 10 mm for low-power setups; the exact limit depends on the material grade and surface, assist gas, optics, and the overall cutting machine configuration.
