VPR series vacuum turntable

The VPR series vacuum turntable is made of vacuum-compatible materials and is driven by a worm gear. It can be equipped with an optional vacuum-specific incremental circular grating and dual reading heads to achieve high-precision rotation. Closed-loop control is achieved with a self-developed controller, which is very suitable for precision motion fields in vacuum environments.
