ABTech’s standard line of high precision, air-bearing rotary tables (AT Series) and heavy-duty rotary tables (HDRT Series) are ideal for low-speed TIR measurements, optical inspection, precision assembly, or light machining and grinding where radial and axial accuracies down to 2.0 µ” are required. These are available with tilt and center worktables, precision fixtures, 3-jaw chucks, vacuum feed through the center, and motor drives. They are manufactured with 440CSS and hardened to 58 – 60 RC, making these rotary tables the most robust available.

AB Series Air Bearing Spin Tables Rotary tables with high accuracy motion for assembly, test and inspection The AB Series tables utilise air lubricated hydrostatic bearings designed to provide very high radial and axial stiffness. This type of bearing offers significant advantages over conventional rolling element bearings permitting operation with minimal drag vibration and mechanical noise. The design principle of these bearings ensure axial laminar flow between shaft and housing compared with conventional orifice entry arrangements thereby ensuring exceptionally good motion geometry. From 200mm to 600mm diameter rotary spin tables with high geometric performance for assembly, test, inspection and metrology applications. High grade stabilised cast iron base and rotary platen, ensure rigidity and precision. Precision hydrostatic bearings designed to provide very high radial and axial stiffness.

PI’s A-630 series of low-profile rotary spindle series was recently extended by the new A-634 rotary spindle stage with 150mm table diameter and the A-638 model with 350mm diameter. Thesehigh precision, high speed direct drive rotary spindlesare only 60mm tall and provide high speed to 3000 degrees/second. For transmitted light applications, the A-688 model with a large aperture is available.

As all of PI’s direct driveair bearing rotary tables, the A-688 high precision spindleis also equipped with absolute measuring feedback encoders for closed loop position control. They provide resolution to 0.0015µrad (0.00003 arcsec), and flatness and eccentricity as low as 175nm and 300nm, respectively.

The rotary spindle tables use low-cogging frameless and slotless torque motors to enable this excellent geometric performance. Different designs allow use in horizontal, vertical or any orientation. Air bearings guarantee a virtually unlimited service life with no wear, and zero required maintenance. As with all other PI linear air bearings and stages, the rotary tables are clean room compatible and requires no lubrication. For transmissive light applications, the A-688 direct drive rotary table with large aperture is available.

The highest motion performance is achieved with PI’s A-800 series of EtherCat-based, high precision motion controllers, ideally suited for closed-loop control of the rotation tables. Advanced algorithms are available to deal with changing load conditions and to suppress external disturbances.

Air-bearings have no mechanical elements such as rollers or slides, and deliver frictionless, non-contact motion, resulting in negligible reversal error, better flatness, and minimal wobble and eccentricity. All these are ideal prerequisites for applications such as inspection and metrology, calibration, and scanning of high-end parts (i.e., infrared and precision optics, turbine blades, shafts and bearings) in industries like aerospace, aircraft, automotive, semiconductors, and photonics.

Rotation tables with air bearings are used when rotary motion with the highest accuracy, smoothness, and geometric performance is required. Due to the lack of friction, these high precision rotation bearings and direct-drive motorized rotary tables can achieve angular resolution in the sub-microradian range. PI’s air bearing design and manufacturing group provides hundreds of man years of design experience along with the manufacturing and test equipment to produce high quality rotary tables with the tightest tolerances.

Rotary air bearings (air bearing spindles) are friction free, and all of PI’s motorized air bearing rotation stages employ closed-loop, non-contact 3-phase direct-drive torque motors, and optical high-resolution rotary encoders for ultra-reliable maintenance-free operation with basically unlimited service life.

Absolute angle-measuring feedback sensors are available to provide closed-loop control with single digit microradian bi-directional repeatability. Direct-drive rotary air bearing tables also provide better eccentricity, flatness, and minimized wobble compared to rotary stages based on mechanical bearings. The friction-free design allows for high angular velocity without vibrations and noise.

Applications of rotary air bearing spindles / motorized direct-drive rotary tables include indexing, metrology, optical lens testing, bio-medical engineering, runout measurements of machined parts, and fiber optics.

PI’s high-performance closed loop servo motor controllers are available to precisely control position, acceleration and velocity, with advanced algorithms.
