The FANUC ROBODRILL AD21SIB5 is a compact, high-performance vertical machining center optimized for precision milling tasks. It features travel distances of 11.81" x 11.81" (+3.94") x 12.99" across the X, Y, and Z axes, respectively, allowing versatile machining within a tightly controlled envelope. The machine accommodates tools up to 7.48" in length and 3.15" to 3.94" in diameter, with a maximum tool weight of 6.61 lbs, supported by a 21-tool automatic tool changer for efficient production workflows. The robust table measures 24.80" x 12.99" with a maximum load capacity of 441 lbs, enabling stable workpiece support. The spindle, with a BT30 holder, rotates at speeds up to 10,000 rpm, delivering a peak torque of 80 Nm (14.2 kW) for one minute and continuous torque of 13.6 Nm (4 kW), suitable for a wide range of materials and cutting conditions. High feed rates are achievable with rapid traverses of 54 m/min and programmable cutting feeds up to 30,000 mm/min. The machine exhibits strong dynamic performance, with accelerations reaching up to 1.6 G on X and Z axes under typical loads. Tool change times are rapid at 1.6 seconds (cut-to-cut), enhancing cycle efficiency. Energy-efficient air pressure consumption is 150 L/min at 0.35–0.55 MPa. At 4,409 lbs, the unit’s structural design balances rigidity with compactness, ideal for precise, high-speed machining in limited spaces.
