AP Series Air Bearing Direct Drive Rotary Tables
2Pages

AP Series Direct Drive Air Bearing Rotary Tables A high precision range offering great versatility at moderate cost. Intended for fine inspection, metrology and test applications. High grade stabilised cast iron base and rotary platen ensure rigidity and precision. A direct drive motor is positioned on axis adjacent to the angular encoder. Radial air bearing constructed of hardened stainless steel. The AP Series tables utilise the same air lubricated hydrostatic bearings as the AB series combined with a direct drive motor and high accuracy angular encoder. The encoder couples directly to the motor control system, which has its own high-resolution interpolator. The system ensures high motor stiffness, precise positioning and repeatability. Torque motor maintains platen position during measuring process. Measuring Systems Precision angular encoders set on axis with DRO or NC systems. Direct drive motor is positioned on axis. The system has the capability to increment to extremely fine levels. The Heidenhain / Renishaw angular encoder couples directly to the motor control system, which has its own high-resolution interpolator. The system ensures high motor stiffness, precise positioning and repeatability.
