Instead, the lab decided to use a relatively low-cost high-capacity indexer designed and built at Centricity Corp., Girard, Ohio (centricity.net). It had to go from 15 to 115 rpm, and change speed in a few tenths of a revolution. The company combined a round, adjustable-speed indexing table with a slip ring, and a counterbalance system. Operators can program the spinning indexer's motions profile using a touch-screen pendant.
