C.R. Onsrud Inc. 121M - MATE SERIES VERTICAL MACHINING CENTER

This CNC vertical machining center features a robust table measuring 121.000 inches in length by 61.000 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 12.00 HP (30-minute rating) for demanding milling operations. The spindle’s design ensures excellent rigidity and precision, making it suitable for high-performance machining applications. Tooling is managed via a fixed rack system with a capacity for 12 tools, allowing for efficient setup and operation. The machine offers three primary axes (X, Y, Z) with travel distances of 145.000 inches (X), 78.000 inches (Y), and 9.000 inches (Z), enabling extensive part coverage and flexibility. An optional fourth axis is available for enhanced versatility. Maximum feed rates and rapid traverse speeds are both set at 1,400 ipm and 2,500 ipm respectively across all axes, ensuring swift and accurate movements during machining cycles. The absence of a pallet changer and index or rotary table support indicates a focus on straightforward, high-precision milling tasks. This configuration is ideal for industries requiring reliable, high-speed, and accurate machining of large components without the need for automated pallet changing or rotary indexing capabilities.
