Technical Description

This CNC machining center features a robust 3-axis travel capacity with 40" on the X-axis, and 20" each on the Y- and Z-axes, allowing versatile machining of large components. The spindle operates at speeds up to 8,000 RPM, powered by a high-torque 15 HP motor (10-minute rating), with continuous power of 7.5 HP, delivering 51 ft-lb of torque for efficient material removal. It uses a CT40 spindle taper, accommodating a wide range of tooling. The machine is equipped with a 20-station Automatic Tool Changer (ATC), supporting tools up to 3.15" in diameter, 11.8" in length, and 17 lbs in weight, enabling complex multi-tool operations without manual intervention. The working table measures 47.2" x 20" with a load capacity of 700 lbs, suitable for substantial workpieces. Spindle-to-table surface height ranges from 7.87" to 27.87", and the spindle center is positioned 20" from the column for optimum accessibility. Rapid traverse speed reaches 591 inches per minute (IPM), with a cutting feedrate of 157.5 IPM, balancing speed and precision. Structurally, the machine weighs 8,900 lbs and occupies a floor space of 172" x 118" with an overall height of 116". This ensures stability and rigidity essential for maintaining machining accuracy under high dynamic loads. The machine’s specifications make it suitable for demanding milling applications, including tool and die work, aerospace parts, and complex freeform components requiring a combination of large travel, high power, and precise control.
