Onsrud XL-Series

The Onsrud XL-Series is an extra-large format CNC router platform designed for manufacturers that process oversized workpieces — full fuselage skin panels, boat hulls, wind turbine components, large composite molds, and architectural-scale structures that exceed the work envelope of standard production routers. The XL-Series fills a critical gap between conventional production routers and full gantry machining centers, offering the open-bed accessibility of a router architecture combined with the work envelope scale required for truly large-format industrial cutting and trimming applications.

The XL-Series is built on a floor-mounted gantry structure where the moving bridge travels over a stationary work surface, enabling workpiece sizes limited only by the available table length extension. Standard configurations begin at 10-foot gantry widths and extend to 20 feet or beyond for custom installations. The machine's steel fabricated structure is designed for rigidity at scale — an engineering challenge that becomes acute in extra-large format machines where gantry deflection under cutting loads can create dimensional errors that accumulate across long workpieces. Onsrud engineers the XL-Series gantry cross-section and beam height to maintain stiffness-to-weight ratios appropriate for the cutting forces generated in composite and aluminum routing operations.

Spindle configurations for the XL-Series scale up to match the demands of large-workpiece routing: high-power electrospindles capable of sustained heavy cutting in thick composite laminates, with automatic tool changers that carry the tool assortment needed for full-cycle programs on large parts. The Z-axis travel on XL-Series configurations is generous to accommodate the height variation of large molds, tooling fixtures, and formed composite blanks. Multi-axis options (4-axis and 5-axis configurations) extend the machine's capability to contoured trimming operations on curved aerospace structures and boat hull components.

Workholding on XL-Series installations typically involves custom vacuum fixture systems or mechanical clamping integrated into the machine's table structure. Large mold tools and formed composite blanks require workholding engineering specific to the part geometry, and Onsrud's applications team provides fixture design support as part of the machine procurement process. Dust extraction systems scale to match the large cutting volumes generated on long-run programs processing carbon fiber and fiberglass.

The Onsrud XL-Series competes in a specialized segment that also includes large-format offerings from Fives Cincron, Forest Line (Portalign), and custom-built gantry systems from integrators. Its differentiation lies in Onsrud's composite application expertise, US manufacturing and service support, and the ability to specify the machine to a specific production program rather than accepting a catalog configuration. For manufacturers processing truly large composite or wood structures, the XL-Series is a purpose-built answer that avoids the compromises of adapting a standard-format machine to oversized workpieces.
