The ULTRARON is a precision-engineered rotary table, produced entirely at A.G. Davis - AA Gage, with applications for inspection, tool room and/or production machining. The ULTRARON"s accuracy is made possible by the use of precision lapped balls and integral ground races. The ULTRARON has a standard concentricity accuracy of 30 millionths T.I.R. (0.000030) and a wobble or rotating parallelism is held within 100 millionths (0.0001) on sizes to 24" in diameter.

The A.G. Davis - AA Gage Precision Broach Rotary Tables are high precision rotary systems manufactured for precision broaching applications. The Broach Rotary Tables can be supplied with stand-alone or rack-mounted controller, or can be interfaced to your operational Rotary Axis Control.

The Precision Rotary Tables are designed for use in Metrology, Inspection, and other precision applications. The Rotary Tables can be supplied with stand-alone or rack-mounted controllers, or can be interfaced to your operational Rotary Axis Control. The control is a solid-state, closed-loop system incorporating the latest State-of-the-Art concepts and can include IEEE or RS232 interface for remote program control.

The Air Float Rotary Table consists of hardened steel faceplate, which is floated on air in the thrust plane and centered by preload ball bearings radially during rotation. After an index move is completed the Air float is shut off allowing the faceplate to rest on the base of the rotary table producing excellent wobble characteristics. This action also friction locks the Air Float Rotary Table. A high-grade meehanite base casting is used to support the faceplate. Standard faceplate mounting pattern is by threaded hole patterns with other configurations available. The Air Float Type Precision Rotary Table can only be used with the faceplate in the horizontal plane.

The Ball Bearing Rotary Table consists of hardened steel faceplate supported by a maximum diameter preloaded angular contact ball bearing. The large diameter ball bearing produces excellent wobble characteristics. The preloaded ball bearing along with the closed loop servo system provides for continuous as well as point-to-point measuring. A high-grade meehanite base casting is used to support the ball bearing. Standard faceplate mounting pattern is by threaded hole patterns with other configurations available.

The Air Bearing Rotary Table consists of hardened and stabilized stainless steels and/or high-grade steels with corrosion resistant coatings. The base is made from high-grade meehanite castings. The Rotary Table employs a fully trapped gas bearing for both radial and thrust planes. The gas bearing jets are manufactured of precision machined gemstones. The air bearing along with the closed loop servo system provides for continuous as well as point to point measuring. Standard faceplate piece part hold down consists of threaded hole patterns, or special configurations are optionally available.

Air bearings require small clearances between rotating members. The possibility of these surfaces contacting each other during rotation is a major concern of air bearing users. Typically when this touch down does occur conventional air bearings will seize up and require major repairs. A.G. Davis-AA Gage has eliminated this possibility. The air orifice manifold detail is constructed from hardened stainless steel. The opposing surfaces are constructed from high-grade hardened steel and coated with a proprietary material. This construction permits the air bearing to lose air pressure while rotating even under maximum rated load and not damage the air bearing thrust and radial precision surfaces. After the air pressure is reinstated the bearing will freely operate as before.

The servo drive utilizes a capstan type friction wheel drive system. This drive system eliminates backlash (lost motion) between the servo motor and the Rotary Table it must position. The zero backlash condition provides an excellent foundation for a servo system which positions accurately without instability over a wide range of payload conditions.

The drive is constructed to eliminate any side loading of the rotary table bearings. Tangential loading only. This is accomplished by mounting the entire capstan drive package on a pivot which is tangent to the table drive rim. The main capstan drives on the O.D. of the drive rim while an opposing wheel bearing runs on the I.D. of the drive rim. The drive force required to engage the main capstan is provided by the opposing wheel bearing which creates a pinching action on the drive rim. This pinching action along with the pivot allow the drive to follow the drive rim"s motion without imparting any force to the rotary tables precision bearings. Note -unwanted side loading of the rotary table bearing will cause an increase

The base of the rotary table can be provided with air jet pads. These pads when actuated allow the rotary table to float on a level continuous flat surface. This feature is particularly convenient to CMM users who often move the rotary table to other locations on the CMM for various applications. The Air Ride is actuated by a dead man switch (automatically turns off when released). The switch is located adjacent to the drive cover.

A micro switch can be provided to close approximately 10° to 15° before the encoder"s marker pulse. The approach direction can be either clockwise or counterclockwise. Specify the desired approach direction when ordering. The encoder marker pulse will be located within 5° of the rotary tables zero position (the RT outline drawing shows the rotary table at it"s zero position).

A switch (DISENGAGE/ENGAGE DRIVE) can be provided adjacent to the drive cover. This toggle switch actuates a cylinder that alternately disengages and/or engages the drive. This switch also turns the Air Float Bearing on and off. This permits freewheel rotation of the face plate for faster centering and complete manual operation.

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.
