C.R. Onsrud Inc. 244E - EXTREME DUTY SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust 60.000" (L) x 120.000" (W) table, providing ample work support for large and complex parts. Designed for high-speed precision machining, the machine is equipped with a vertical spindle utilizing an HSK 63F taper, capable of reaching top speeds of 24,000 RPM and delivering 18.00 HP (30-minute rating) for demanding cutting operations. The spindle’s high-speed capability and advanced tooling interface ensure optimal performance for a wide range of materials, including metals, plastics, and composites. Tool management is handled by an automatic tool changer (ATC) with a 12-tool capacity, streamlining production and reducing downtime. The machine operates on three primary axes (X, Y, Z), with optional support for a fourth axis to expand machining versatility. Axis travels are extensive, with X1 at 82.000", Y1 at 340.000", and Z1 at 12.000", allowing for large workpieces and deep cuts. Maximum feed rates reach 4,000 ipm across all axes, while rapid traverse speeds achieve 5,600 ipm, ensuring fast and efficient movement for both roughing and finishing operations. The absence of a pallet changer and index or rotary table support indicates a focus on straightforward, high-volume machining tasks. This configuration is ideal for industries requiring high-speed, high-precision milling, drilling, and tapping, with the flexibility to adapt to various production needs.
