Case Study: High speed, high acceleration, long travel, high payload, high precision XY gantry with self- correcting XY orthogonality system. Background: Primatics was contracted to design and build a 5-axis, high precision sorter system. Two of the axes were to be in a gantry form of a 500 mm travel Y, Y’ with a 1300 mm travel X cross axis supported by the Y carriages. The X carriage was to carry a 50 mm travel Z axis which in turn would carry the customer’s 9 kg tool set. The gantry was to be built on a granite plate supported by a welded steel frame with the Y & Y’ axes elevated above the plate on 171.5 mm tall granite risers on the right & left sides. A cable management system from the granite plate to the Z axis for the customer’s tools was also to be provided. The
