C.R. Onsrud Inc. 146C - SUPER DUTY SERIES VERTICAL MACHINING CENTER

This vertical machining center features a robust table measuring 144.000 inches in length by 60.000 inches in width, providing ample work support for large or complex parts. 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. The spindle’s design ensures excellent rigidity and precision, making it suitable for high-speed and high-accuracy applications. Tooling is managed by an automatic tool changer (ATC) with a 12-tool capacity, enabling efficient and uninterrupted machining cycles. The machine operates on three primary axes (X, Y, Z), with optional support for a fourth axis, allowing for versatile part processing. Axis travels are extensive, with X-axis movement up to 71.000 inches, Y-axis up to 164.000 inches, and Z-axis up to 11.000 inches, accommodating a wide range of workpiece sizes. Maximum feed rates are 3,600 inches per minute across all axes, while rapid traverse speeds reach 4,800 inches per minute, ensuring fast and efficient tool movement. The machine does not include a support index table, rotary table, or pallet changer, focusing on core milling and machining tasks. This configuration is ideal for industries requiring high-speed, high-precision vertical machining with reliable performance and flexibility.
