ultradex rotary table for sale

The ULTRADEX MK II & III Indexing Table is designed for precision machining, inspection, calibration, test gear and other applications where absolute rotary positioning accuracies of 1/2 arc second band tolerance not accumulative (+/- 1/8 arc second) or better are required, with a repeatability accuracies to +/- 1/20 arc second. The system utilizes a process for very accurate serrations (teeth), which not only provides very accurate indexing, but also establishes a very rigid coupling when clamped in position, forming almost a solid column of steel. The tables are manufactured for manual indexing applications; automatic tables are available (consult factory). They are supplied with a wide range of indexing positions varying from 180 to 1440. Accessories (Not included) are for sub-dividing the positioning increments, by both mechanical and electronic means, to give an almost infinite number or rotary positions.

To the best of my knowledge, Ultradex was the AA Gage tradename for a very precise rotary indexer that used a pair of face gears to divide the circle into aliquot parts. Face-gear couplings have been made in two main flavors; the Hirth coupling uses straight-flank radial teeth, and the Gleason "Curvic" coupling uses radial teeth having convex / concave flanks.

My first experience with an Ultradex table was 40 years ago, and the table itself was decades old at the time. It had a 360-tooth pair of face gears, providing 1-degree +/- 1/2 arcsecond indexing increments. An angle generated by indexing the table to two different positions would therefore have a maximum error magnitude of 1 arcsecond. A later generation Ultradex offered single-position indexing within 1/4 arcsecond magnitude.

The original Hirth and Curvic couplings required raising the table itself off its base to de-couple the coupling. A non-rising variant was developed later, based on 3 face gears. Two of the face gears are concentric. One is fixed to the inside of the base, surrounding a second that is fixed to the underside of the platen. These two face gears do not contact each other.
