The heavy-duty Fanuc RoboDrill eco VMC offers high-speed milling, drilling, tapping, deburring and chamfering. The machine is named for its ecological spindle that returns energy to the machine in the intervals between cutting. It has a working cube of 19.7″ x 15.7" × 12.9", feed rates of as much as 1,181 ipm, rapid traverses of as much as 1,890 ipm, accelerations of as much as 1.5G, 0.8-second tool changes (tool-to-tool), rigid tapping to 5,000 rpm and high-speed reverse tapping. The machine’s Fanuc 31i CNC has simultaneous three-axis control (expandable to four-axis). Other standard features include a 14.75-hp (peak), 10,000-rpm direct-drive spindle with precision-enhancing thermal compensation and HRV control, a 14-station toolchanger, an auto lube system and an interior work light.
The VMC’s speed and versatility make it suited for off-loading larger, slower machines as well as for performing secondary operations, regardless of production volumes. Options include high-speed indexers, a fourth axis, a signal lamp and robotic loading.
