The compact gantry delivers extraordinary speed and precision, requiring rigidity beyond the ordinary. Modig integrated cast iron bridges into the gantry structure to achieve the needed stability. It resulted in a gantry weighing slightly more than three elephants. Despite its weight, the RigiMill is a high-speed single-spindle gantry and accelerates at 26 ft/s2 (8 m/s2), while maintaining a feed rate of 2,800"/min (70 m/min). How is this possible?
While the compact gantry weighs approximately 20 tons, the African bush elephant generally weighs 6 tons. This implies that a RigiMill MG gantry is heavier than three elephants or 11 cars, or 322 people.
Key to RigiMill's unique combination of strength, speed, and agility is the synergy of the machine's unique architecture and advanced technology. Even when the spindle works at full speed, 30,000 rpm,
RigiMill works with the highest steadiness, thanks to the cast iron monolithic portal integrating five guideways to provide the spindle with the required rigidity to handle heavy cutting.
