AccuRing rotary tables provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives. Low maintenance and high throughput characteristics of the AccuRing stage yields the lowest total cost of ownership.
Compact package and Superior design of the AccuRing rotary stages was optimized to minimize stage height. The low profile of the stage reduces total system working height. Angular contact bearings are used to maximize performance with respect to wobble, moment stiffness and friction. AccuRing stage has large clear center aperture that can be used for air or wire line feed-through or beam delivery.
AccuRing utilizes direct drive three phase brushless motor technology. There are no brushes to replace and no gear trains or belts to maintain. Coreless magnetic design assures smooth rotation and dynamic performance.
Accurate Positioning is assured with contact-less encoder. The motor and rotary encoders are directly coupled to eliminate coupling backlash. The low inertia and zero backlash make AccuRing the ideal solution for applications requiring frequent directional changes.
