Danaher Motion introduces the rotary indexer product set. This fully programmable direct drive solution provides electronic indexing in a package that delivers an increase in throughput compared with mechanical indexers, with no maintenance over the entire life of the system. "The Danaher Motion rotary indexer product set provides unmatched operational performance and flexibility, allowing OEMs to build a better machine, faster, and end-users to precisely assemble even the smallest of parts faster with far less scrap and better yield, while actually lowering the cost of ownership over the life of the machine," says Dennis Gallagher, vice president of systems for Danaher Motion. "This solution enables users to achieve software selectable motion sequences that run circles around mechanical indexer capabilities. Precision technology allows for superior repeatability to +/-1.2 arc-sec, with no backlash and system accuracy to +/-26 arc-sec. In comparison, mechanical indexers typically provide best-case repeatability to +/- 33 arc-sec and accuracy to+/-66 arc-sec," he says. According to the company’s press release, Danaher Motion’s rotary indexer product set is programmed to go in any direction, at any speed, and at any angle. This feature is important to system integrators that deal with multiple product designs, including custom machines, as they are able to use a single indexer solution to satisfy any number of requirements. Additionally, should the demands of the manufacturing process change, this flexibility would allow the end user to update the motion sequence to satisfy their application needs. This indexer product set can rotate both clockwise and counter-clockwise to achieve the shortest cycle time and increased throughput. Index times are programmable and no honing is ever required, as absolute position feedback maintains position even under power cycling. Additionally, users will benefit from a noticeable 20dB reduction in system noise when compared with mechanical indexers. The Danaher Motion rotary indexer product set is lubricated for life and requires no maintenance over the entire life of the machine.
