C.R. Onsrud Inc. 333G - PRO SERIES VERTICAL MACHINING CENTER

This CNC vertical machining center features a robust worktable measuring 333.000 inches in length by 61.000 inches in width, providing extensive support for large workpieces without the need for an index or rotary table. The spindle is oriented vertically and equipped with an HSK 63F taper, capable of reaching a maximum speed of 24,000 RPM, ensuring high-speed precision machining. The spindle delivers 18.00 HP (30-minute rating), suitable for demanding milling operations. Tooling is managed via a 12-station automatic tool changer (ATC), enabling efficient tool swaps and minimizing downtime. The machine operates on three primary axes (X, Y, Z), with an optional fourth axis for expanded versatility. Axis travels are substantial: X-axis at 345.000 inches, Y-axis at 78.000 inches, and Z-axis at 11.000 inches, accommodating a wide range of part sizes. Maximum feed rates for all axes are 2,500 inches per minute, while rapid traverse speeds reach 3,500 inches per minute, ensuring swift and accurate positioning. The absence of a pallet changer maintains a streamlined configuration, ideal for applications where part size and complexity are prioritized over high-volume production. This machining center is engineered for high-precision, high-efficiency operations in industries requiring large-scale milling, such as aerospace, automotive, and heavy manufacturing.
