This article describes a transfer mechanism that provides accurate workpiece location and repeatability on the order of 0.0001 inch while providing the workpiece carrier an additional degree of freedom of precision movement within the workstation. The transfer mechanism consists of an air bearing and magnetic circuit combination which allows the carriers to be easily removed from the precision guide and restarted at the beginning for recirculating the carriers.
