ultradex rotary table factory

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 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 are supplied 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.

Moore Tool manufactures a complete line of high precision, CNC positioning and contouring rotary tables from 12 inches (305 mm) to 96 inches (2.4 m) in diameter. We also offer service and remanufacturing services on tables that we have built.

The Moore 1440 Precision Index is a serrated-tooth circle divider of highest accuracy using two face gears of identical shape and pitch. During operation, the table is displaced axially to disengage the teeth and radially to the desired angle. The instrument is guaranteed to be accurate to within ±0.1 second of arc at any of the 1440 indexed positions

We were selling the precision index table called "Ultradex®" and manufactured by AA Gage in Japan. Last year we were talking about this "Ultradex®" with an engineer of a customer and have fixed the specification after several discussions per E-mail. Then we were asked about this inquiry by the purchase department whether we are the sole agent or not. We had some experiences to sell "Ultradex®" to Japanese customers, however we have not yet discussed about this distribution issue with Manager of Firm A.G. Davis - AA Gage, after AA Gage joined with A. G. Davis. We answered the customer that we are not a sole agent but we can directly buy "Ultradex®" and do the after sales service in Japan. However the customer bought it through a Japanese company in the States, then the manufacturer had to sell it to him. It is unfair, because we have decided the specification after discussion with the customer�fs engineer. The Japanese company knew only the Type Number of the "ULTRADEX®" and he could buy it and sell it with his lowest commission. We are not big, so we cannot take the responsibility to be a sole agent in Japan. But the manufacturer wrote for us the Certificate of the Sales Representative in Japan. We can of course sell all products of Firm A.G. Davis - AA Gage, and we will do our best with our good faith to the customer who contacts with us as in the past. Please watch and ask us with warm look, thank you.

A trading company asked us whether we can import the A.G. Davis Groove Gage, after he saw our web site. According to him the end use uses the Groove Gage as the photo of the right side, and the gage was engraved the name of A.G. Davis on it. The end user wanted to change the dimension. We were importing the "Ultradex®" of AA Gage, however we had not yet contacted with Firm A.G. Davis - AA Gage, after AA Gage joined with A.G. Davis. And we begun to contact with Firm A.G. Davis - AA Gage, we could place an order after several E-mai exchanges, and we could deliver the Groove Gage without a problem. After this in the future we were recognized to import the goods from Firm A.G. Davis - AA Gage directly.

CNC rotary tables play a vital role in the performance of multi-axis machining centres. As table accuracy and reliability are of paramount concern throughout the product"s lifetime, Matsumoto Machine Corporation (MMK) has taken a pragmatic two-pronged approach to reducing indexing errors and improving performance. By enhancing both product calibration and encoder technologies the company has set new standards for rotary table accuracy.

Founded in Japan in 1948, Matsumoto Machine Corporation is a technology-leading provider of innovative, high quality jaw chucks and numerically controlled rotary tables used by industrial machine tool makers throughout the world. A key feature of MMK"s CNC rotary tables is a patented worm and wheel gear assembly developed by OTT GmbH, Germany. Unlike double lead worm gears, the OTT worm and wheel gear is able to minimise backlash, ensuring outstanding accuracy and long life, efficiency and durability.

A further advantageous characteristic of the MMK CNC rotary table is a large diameter through-hole in the table spindle. This greatly increases machine versatility and rigidity, supporting a wider variety of chucks and jigs and the machining of longer workpieces.

By enabling most metal-machining operations to be undertaken on a single machine, the benefits of MMK CNC rotary table are far-reaching. These include the time and cost saving of single machine set-up and single fixturing setup, reduced parts handling and the elimination of tolerance errors as workpieces pass from machine to machine.

Of critical importance in this one-hit machining centre scenario is ensuring the high accuracy of CNC rotary table indexing and control throughout its working lifetime.

As with a machine tool"s linear XYZ axes, the rotary axis is just as susceptible to uncontrollable events that may introduce angular positioning or axis alignment errors. Risking the production of defects in finished parts, these errors can be due to a number of reasons including, mistakes made in the initial machine installation, impact damage caused by collision or general wear-and-tear in use.

With its global reputation for product quality and design innovation, MMK therefore sought to equip its CNC rotary tables with a highly accurate and reliable means of tracking and controlling the indexing of its product throughout its lifetime, irrespective of the type of machine tool, workpiece complexity and duty cycle.

At the same time, in an increasingly competitive global market for CNC rotary tables, MMK also wanted to further enhance its product quality inspection processes. Specifically, the company set itself the task of augmenting index angle measurement as a key component of pre-shipment quality assurance procedures.

To provide machine tool makers and users with the ability to accurately track and control CNC rotary table indexing, MMK elected to integrate Renishaw"s super-compact TONiC™ non-contact optical incremental encoder system. Simple to install and with a compact readhead measuring just 35 mm x 13.5 mm x 10 mm, the TONiC encoder presented MMK with a minimal footprint solution capable of supporting machine speeds up to 10 m/s and resolutions down to 1 nm.

The rotary table readhead was designed to be used in conjunction with Renishaw"s RESM, a one-piece stainless steel ring marked on its periphery with 20 µm pitch graduations and featuring the IN-TRAC™ optical reference mark. With its low profile, large internal diameter and wide choice of diameters from 52 mm to 550 mm, the high stability RESM ring provided MMK with a versatile and easy to integrate scale that is well-suited to the company"s wide range of CNC rotary tables.

MMK selected Renishaw"s compact and lightweight XR20-W rotary axis calibrator to verify the accuracy of its rotary tables during manufacturing and immediately prior to shipment. The XR20-W was used in conjunction with Renishaw"s XL-80 laser interferometer to provide a non-contact reference measurement, independent of the axis under test, with an accuracy of ±1 arc second.

Motorised by a servo-controlled drive and with data capture synchronised to axis movement, the XR20-W requires no operator intervention during measurement. Being lithium battery powered and Bluetooth enabled, it ensures quick and easy setup, and the avoidance of trailing cable hazards. The calibrator"s modular design and flexible mounting systems allow far easier setup than alternative solutions and can be readily configured for a wide variety of rotary tables, chucks and spindles.

By integrating Renishaw"s TONiC non-contact optical encoder system into its CNC rotary tables, MMK has further assured the accuracy and reliability of its products in the field, along with an overall superior motion control performance. For a wide range of different machine tools and end uses, the rotary tables" combination of compact readhead and one-piece stainless steel ring scale has delivered a higher level of tolerance to dust, scratches, grease and oil, and a reduction in indexing errors. The encoder system"s ability to output highly stable position signals of unrivalled purity and ultra-low sub-divisional error have provided smoother velocity control, improved scanning performance and increased positional stability.

MMK"s introduction of Renishaw"s XR20-W rotary axis calibrator and XL-80 laser interferometer has reduced product measurement times by a half compared to conventional autocollimator techniques. Measurement procedures have been simplified and automated. Capable of taking accurate measurements at any indexing angle pitch, the calibrator enables evaluation of the accuracy of the worm and wheel gear-driven table for ultra-fine pitch measurement movements as small as 0.001°. This has allowed any loss of motion control or worm and wheel gear efficiency to be evaluated in detail and addressed. Product performance is now backed by a thorough analysis meeting ISO quality standards.
