Direct drive rotary table with large center aperture features exceptional positional accuracy, according to distributor IntelLiDrives.
AccuRing series direct-drive rotary stages provide superior angular positioning and velocity control with exceptionally large apertures, the company says.
Advantages of AccuRings inlclude large aperture rotary stages with zero backlash, with no gear wear or gear vibration models now available.
According to IntelLiDrives, direct drive AccuRings are significantly faster than worm and gear drives, and system accuracy and repeatability of the stage will be maintained over time. Higher accuracy and no backlash also allows customers to produce more accurate and consistent products, the company says.
Applications for the AccuRings include single and multi-axis laser testing, antenna testing, inertial navigation device testing, photonic component alignment, high-accuracy laser machining and precision wafer inspection. These rotary stages can also be configured as multi-axis gimbals.
InteLiDives says that the AccuRings also offer high speeds, as conventional transmission-based rotary tables with similar apertures and payload capacity operate only to 10 rpm or less. AccuRing direct-drive stages have been tested to 800 rpm continuous rotation, the company claims.
AccuRings also offer superior mechanical design, with angular contact bearings used to maximise performance with respect to wobble, moment stiffness, and rotating friction. A precision-machined rotating shaft further minimises wobble, the company says.
