Mechanical-Bearing Rotary Tables

Superior Mechanical Motion

ABTech mechanical stages are superior in performance and quality. The key to high-performance rotary tables is in the geometry and quality of the mating components. By leveraging our knowledge and experience gained in producing the extreme tolerances required for air bearings, ABTech mechanical bearings achieve radial and axial error motion of < +/-25.0 µ” (+/-.63 micron).

Configuration Flexibility to Meet Your Specific Needs

Part of our “Pride in Precision” philosophy means providing you with the precise solution needed. We don’t believe in selling our customers more, or less than what their application calls for. No matter how broad our product options are, we realize they don’t address every possible application. Our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.

Motor Drive Options

With proper selection and integration of high-performance brushless DC servo motors ABTech’s air bearing rotary tables provide ultra-smooth and precise rotary motion. With high torque, high performance motor drives, our motion experts will gather your specific requirements and work closely with our motor suppliers to create/select a motor drive that suits your specific application. Whether you need sub-micron position accuracy with minimal settle time and stringent following error specifications, high-speed constant motion, or a combination of both there is an ABTech rotary table that will meet your needs.

The motor drives are designed to accommodate a wide range of precision motion applications such as optical metrology; circular geometry gages; and micro machining with ultra-precision scanning, velocity control, speed regulation and precision indexing.

ABTech’s modular design approach facilitates multiple system configurations to optimize the price-for-performance required in your application. This approach allows the user to define the level of control desired for the most cost-effective solution. Our complete engineering services allow us to respond quickly to provide a solution to your O.E.M. requirements for ultra-precision rotary motion.
