C.R. Onsrud Inc. 4100M - MATE SERIES VERTICAL MACHINING CENTER

This CNC vertical machining center features a **large fixed worktable measuring 161" x 82"**, designed to accommodate substantial workpieces without a support rotary or index table. The machine operates with **3 axes of travel (X, Y, Z)**, offering precise movements up to 199" in X, 99" in Y, and 9" in Z, each with a maximum feed rate of 1,400 ipm and a rapid traverse rate of 2,500 ipm. The vertical spindle is equipped with an **HSK 63F taper**, capable of speeds up to 24,000 RPM powered by a 12.0 HP motor rated for 30-minute duty cycles, delivering high-performance machining with light cutting torque suitable for high-speed applications. Tooling capacity includes a **fixed rack with 12 tools**, supporting quick tool changes though without a pallet changer. The system does not include a U axis but supports up to 4 axes optionally. This configuration is ideal for large-format precision milling, drilling, and reaming tasks in industries requiring extended table travel and high-speed spindling for efficient production of large or complex parts. The spindle's HSK 63F taper notably supports high rotational speeds up to 24,000 RPM with reduced taper diameter for enhanced speed capability while maintaining excellent concentricity and tool stability. Overall, this machine is engineered for demanding, high-throughput manufacturing environments requiring robust table area, precise three-axis motion, and high spindle power combined with rapid feed rates.
