    Product Manual

    When cutting thin sheet and metal tubes at low power, our 3kW fiber laser cutting heads with manual focus can keep the cutting process simple and the results uniform. This series of laser cutting heads are easy to maintain: the press-fit dust cover seals the optics during cutting yet comes off quickly for cleaning or for a protective-window change. The lightweight body reduces load on the cutting machine axes, which helps motion stay precise at speed. A compact nose and stable focus also improve material use, so parts can be nested closer on sheet, tube remnants are shorter, and overall scrap is lower.

    These heads use a press-fit front cover that seals the optics from dust and spatter, extending protective-window life. It comes off quickly for cleaning or window changes, so maintenance is simple.

    The small, low-mass housing simplifies mounting on flatbed and tube cutting machines. Lower moving weight reduces load on the axes and helps motion stay precise at production speeds.

    The front end is shaped to clear clamps and fixtures, giving more usable stroke near the cut. That means tighter sheet nesting and shorter tube remnants, improving overall material yield.

    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.
