Motion Control / Air Spindles and Rotary Motion

AA Gage Ultradex 5" round base optic-mechanical polygon

The Ultradex indexing table is designed for precision machining, inspection, calibration, test gear and other applications where absolute rotary positioning accuracies of ¼ arc second band tolerance not accumulative or better are required, with repeatable accuracies to +/- 1/20 arc second.

This system utilizes a patented process for producing very accurate serrations (teeth) which not only provides very accurate indexing, but also establishes a very rigid coupling when in the clamped position, forming almost a solid column of steel.
 

Features:

· Rotational Angular Accuracy - +/- arc second absolute

· Repeatable accuracy - +/- 1/20 arc second

· Concentricity, clamped position – 0.000015”

· Parallelism, table top to pitch line of teeth – 0.000015”

· Parallelism, table top to bottom of base – Units up to 18” diameter, 0.0001”. Units 24” to 32” diameter, 0.0002”

· All contact making parts, steel, hardened and ground

· Positive indexing – Serrated plates

· Mating Teeth – Hardened, ground, lapped

· Top plate drilled and tapped – bolt hole pattern varies with table diameter

· Running seals to minimize the entrance of chips, dirt, and other foreign particles (7” and greater diameter models.)
