Rotary indexing table ABTech Inc

RIT200 Worm Gear Drive Ball Tables

ABTech's high precision mechanical rotary index tables combined with Heidenhain's RON 200 series encoders and ND 200 series single axis displays make an ideal set up for high precision light-duty machining or metrology inspection.

The rotary tables feature sealed 4-point angular contact bearings, providing high stiffness and radial error motions of 50 µ"(1.25 µm) or better.

The drive is a bronze worm gear (50:1) manually driven by an ergonomic hand wheel. The modular design approach accomodates motor driven versions, including amplifier/controller options and complete turn-key systems.

The single axis display provides easy operation and easy to read digital display. An RS-232-C interface is available as well as switching inputs and outputs for simple automation environments.
