Mag’s new six-axis FTR AutoDrill combines a rigid boring mill chassis and an extended-reach ram with a powerful gimbal head for precise milling and drilling. This machine is equipped with minimum quantity cryogenic (MQC) liquid-nitrogen tool cooling. MQC delivers liquid nitrogen at -321°F (-196°C) directly to the tool tip and cutting zone through the spindle. It is capable of drilling assembly holes and milling section edges, windows and door cut outs.
The machine is a hybrid floor-type horizontal boring mill equipped with a two-axis spindle carrier. It features a Fischer 15-kW (20-hp) 24,000-rpm spindle equipped with an HSK-50A tool interface and power drawbar. The traveling-column design has an X-Y-Z work range of 12 × 3 × 1.4 m (472" × 118" × 55"), with X-Y repeatability of 0.0076 mm (0.0003") and Z-axis repeatability of 0.020 mm (0.0008"). A feed rate of 20,000 mm/min. (787 ipm) for X and Y axes is said to enable rapid and efficient machining of large components.
The machine can maintain tool point accuracy over the ram’s full 1.4 m (55") extension and the integrated gimbal machining head provides ±200 degrees of C-axis rotation and ±90 degrees of A-axis tilt. High-performance torque motors on the A and C axes enable positioning rates as much as 60 degrees/sec. (10 rpm). A W-axis drilling quill provides 100 mm (3.98") feed stroke perpendicular to the Z axis for precision drilling. The machine features a column-mounted, double-arm tool changer and 30-pocket drum-type tool magazine; a Renishaw TS27R tool setting probe; an RMP 600 strain-gage spindle probe; and a 482 mm (19") flat-panel monitor for visual observation of the work zone.
The modular FTR AutoDrill is available in a variety of sizes and can accommodate both fixed and rotating tool types. In addition to cryogenic tool cooling, the machine can be configured for dry machining or with standard liquid coolant or minimum quantity lubrication (MQL). The machine can also be arranged for single or multi-station production and can easily be incorporated into flexible manufacturing cells.
