C.R. Onsrud Inc. 148E - EXTREME DUTY SERIES VERTICAL MACHINING CENTER

This vertical machining center features a large worktable measuring 60.000 inches in length by 144.000 inches in width, providing extensive support for oversized workpieces. The machine is equipped with a high-speed vertical spindle utilizing an HSK 63F taper, capable of reaching up to 24,000 RPM and delivering 18.00 HP (30-minute rating) for demanding milling operations. Tooling is managed by a 12-station automatic tool changer (ATC), ensuring efficient tool exchange and reduced downtime. The machine operates on three primary axes (X, Y, Z), with an optional fourth axis for expanded machining flexibility. Axis travels are substantial, with X-axis movement up to 82.000 inches, Y-axis up to 212.000 inches, and Z-axis up to 12.000 inches, accommodating a wide range of part sizes and geometries. Maximum feed rates and rapid traverse speeds are both set at 4,000 inches per minute and 5,600 inches per minute, respectively, across all axes, enabling fast and precise material removal. The absence of a support index or rotary table focuses the machine’s capabilities on straightforward, high-accuracy milling tasks. Designed for versatility and productivity, this machining center is ideal for applications requiring high-speed, high-precision milling of large or complex components, with robust construction and advanced spindle technology supporting consistent performance in demanding production environments.
