PI USA - Difference between Gantry & Split-Bridge
A traditional gantry system employs X-Y or X-Y-Z range of motion. Mounted on a base plate, usually granite, 2 parallel rails constitute the synchronized Y axis motion while the cross axis (bridge axis) provides the X motion. A vertical axis can be added on the bridge for the Z motion. A Split Bridge system can be less complex than a traditional gantry system because synchronization of the two parallel linear motors is not required. Both systems are used in industrial production, testing, and additive manufacturing.
