C.R. Onsrud Inc. 122E - EXTREME DUTY SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust table measuring 60.000 inches in length by 120.000 inches in width, providing ample 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 speeds up to 24,000 RPM, ensuring high-performance machining for a variety of materials. The spindle delivers 18.00 horsepower (30-minute rating), making it suitable for demanding cutting operations. Tooling is managed by an automatic tool changer (ATC) with a capacity for 12 tools, streamlining production and reducing downtime. The machine operates on three primary axes (X, Y, Z), with an optional fourth axis available for expanded capabilities, though no U axis is included. Axis travels are extensive, with X1 covering 82.000 inches, Y1 spanning 188.000 inches, and Z1 reaching 12.000 inches, allowing for large-scale machining tasks. Maximum feed rates are set at 4,000 inches per minute across all axes, while rapid traverse speeds reach 5,600 inches per minute, ensuring efficient movement and reduced cycle times. This configuration is ideal for high-speed, precision machining applications in industries requiring large work envelopes and rapid tool changes, with no pallet changer available.
