Our dual trunnion assembly systems are typically driven with our RT Series indexer package. The RT200 freely programmable indexer is packaged with zero backlash reducer and driven by an aux axis servo motor. Using our RT high accuracy zero backlash indexers on all three axis provides an unmatched accuracy and repeatability against other auxiliary axis systems utilizing gear mechanisms for these axis. On the dual trunnion the tailstock is the same housing output bearing and flange as the RT200 indexer driving the headstock to give a uniform symetrical design.
View our video to learn the difference between using a Gearhead for a headstock tailstock drive and our TMF300 fully programmable indexer providing single digit accuracy for our custom dual trunnion assembly.
