Allenair carries Index Table. We have descriptions and specifications, principle of operation, standard index table, size and capacity and model 725 counterclockwise rotation.

ALLENAIR ROTARY INDEX TABLES are precision indexing mechanisms . . . unsurpassed in accuracy, performance and dollar value. We know of no other Tables of equal accuracy and quality available at comparable prices. Every detail of construction is designed to increase durability and efficiency, and provide for long, trouble-free life. All parts susceptible to wear are carefully hardened. Bronze and roller bearings are incorporated. Working parts are completely enclosed to protect against dust, dirt, and chips.

The Tables affect substantial savings in time and money in a wide variety of applications. For example, the Tables permit fast, automatic feeding of parts to tools in machine and assembly operations. Parts can be loaded and unloaded while machining operations continue. Other applications include cleaning and positioning operations, as well as use in conjunction with conveyor drive units.

ALLENAIR ROTARY INDEX TABLES are available in a COMPLETE PRODUCT RANGE of four basic models, and each model can be supplied with any one of the following operating options.

As a basic Table with a Single Solenoid Pressure Pilot 4-way Valve (VSSAP-AAS-1/4), a 3-way valve (V23), and piped with flexible air hose ready for use.

Among the many indexer manufacturers, what sets Pascal’s indexing table apart is undoubtedly its brakeless design, compact size, and durability. It has an ample amount of ports lending itself well to automation.

Pascal’s MDF index table operates with a 90° index 0.5 sec. Its unique rolling gear transmission is maintenance free and can operate with high index speed and accuracy for a long time unlike traditional worm gear. Traditional worm gear undergoes abrasive wear that can lead to backlash causing machining failure and degrading index accuracy.

Pascal’s high-performance rotary unions are integrated to enable clamp sensing and actuation but also provides a footprint 20% smaller than its competitors. Ideal for indexing large workpieces in compact machining centers, you will also achieve increased production capacity. As one example, our rotary indexing table can allow a machining center to increase their production capacity from 16 robodrill units to 24 units in the same amount of space.

The MDF index table has a total of 20 ports, lending itself well to automation. 18 of those ports can be used for hydraulic and air, while 2 are for coolant. A double acting cylinder with sensing can be used instead of a single cylinder, and its rotary joint accommodates a 7MPa pressure circuit.

Pascal is confident in the quality and reliability of our rotary indexers so much so that we use them in our own factories. That is also why these indexers are utilized in the factories of major automakers around the world.

PI’s direct-drive rotary tables with frictionless, brushless, closed-loop torque motors provide the best combination of high accuracy, high velocity, and maximum service life. PI provides closed-loop direct drive rotary tables with both mechanical bearings and air bearings. Stage models with large apertures and low profile are available. The stage design is optimized for high speed, stiffness, and high load capacity. If completely friction-free and maintenance free motion with virtually unlimited lifetime is required, air bearing rotation tables are recommended. These ultra-precision, high-speed rotary tables provide vibration-free motion with extremely high accuracy and negligible runout, wobble and eccentricity errors. The lack of lubricants makes these also clean room compatible and ideal for any high-performance metrology application in optics, photonics, and semiconductor manufacturing, test and metrology related projects.

In contrast to worm gear driven rotary stages or belt-drive rotation stages, torque-motor direct drive stages eliminate play in gears, couplings or flex in drive belts, providing motion with zero backlash and excellent constancy of velocity, while achieving higher speed than worm-gear drives.

PI’s precision direct-drive, positioning tables can be used in high performance factory automation, research, semiconductor, and laser processing applications. Due to the use of brushless high-torque, motors with direct metrology position feedback, backlash is completely eliminated, and reliability is greatly improved.

With modern direct-metrology rotary encoders, sensor resolution down to 1/100th of a microrad is available on select models with large rotary table platforms, using the high interpolation factors

Based on the high encoder resolution and powerful servo controllers, the direct-drive rotary tables also provide excellent velocity control, which is required in automation applications including high-speed laser processing, indexing, and semiconductor wafer inspection.

Most Direct Drive Rotation stages can be mounted horizontally and vertically, and with combinations all 3 rotary degrees of freedom (3DOF, pitch, yaw, and roll) can be addressed.

The DKX-TR/RT series, as a combination of a rotary actuator and a linear actuator, perfectly integrates the two and reduces the volume to the extreme, and provides an optimized solution for some special applications that require both translation and rotation.

A rotary table used in conjunction with a mill allows a machinist to produce virtually any part they can design. Sherline’s rotary table is a precision piece of equipment that has been designed to work with their vertical milling machines. However, it can be used on any mill whenever the small 4-inch size would be an advantage. The only limits are size, not complexity.

The table is 2″ high and 4″ (100mm) in diameter. The main components have been machined from solid bar stock steel, and the complete unit weighs seven pounds. The table has been engraved with a laser, giving sharp and precise lines every 5°, numbered every 15°. These lines are calibrated with the 72-tooth worm gear that is driven by the handwheel. The handwheel is divided into 50 parts, making each line on the handwheel 1/10°. This allows a circle to be divided into 3600 increments without interpolation. Seventy-two revolutions of the handwheel rotate the table one revolution.

The rotary tables can hold more weight when they are not under a continuous load. Click on the Video tab above to see examples of different weights and uses for our rotary tables.

The table T-slots are identical to those used on the Sherline mill and lathe, making the vast line of Sherline tooling available for use with this product. Two hold-down clamps and T-nuts are provided with the table. Also included is an adapter that allows Sherline’s 3- and 4-jaw chucks to be screwed directly to the rotary table. An optional right-angle attachment is available (P/N 3701) to mount the table in the vertical position to increase its versatility further. With the table mounted vertically, an optional adjustable right-angle tailstock (P/N 3702) can be mounted to the mill table. It is used to support and stabilize the other end of long work held in a chuck or otherwise attached to the rotary table.

Rotary tables are positioning devices that are oftentimes used in precision manufacturing applications. More specifically, they are tools that hold parts on rotating axes, which increases productivity, accuracy, and repeatability. It seems simple enough, but there are various types of rotary tables. So how do you choose which one is best for you? Let’s go through three common kinds of rotary tables – air-bearing, oil hydrostatic, and mechanical-bearing – to assist you in answering that question.

In many cases, air-bearing rotary tables will be the answer. This is due to the fact that they have the capacity to run longer than other kinds. These are exactly what they sound like; with air-bearing rotary tables, parts float on air above the table. With this, there are no contacting parts to wear the machine down, resulting in decades of maintenance-free motion. That is a significant benefit to any piece of air-bearing equipment, but these rotary tables are specifically beneficial for certain applications.

Similar to air-bearings, oil hydrostatic rotary tables do not have any contacting mechanical parts, as they float parts on oil. These rotary tables are most commonly used for grinding and machining when smooth and repeatable motion is a necessity. They provide high load capacity and can be useful when extreme stiffness is necessary.

Mechanical-bearing rotary tables are a bit different from the other two. Just as the name suggests, this type of rotary table does have moving, touching mechanical parts. And while this does sometimes result in a shorter life than the air-bearing or oil hydrostatic tables, many organizations will still pick these out of the others. Why? They still offer high performance.

These rotary tables can be used in most applications and provide superior performance in radial, axial, and angular error motions. In all, mechanical-bearing rotary tables do the job; however, it is possible that they will not last as long as other types.

The answer to the question, “Which one is best?” is the ever-hated, “It depends!” In general, air-bearing rotary tables will provide the highest accuracy for the longest amount of time. The lack of touching mechanical parts allows this type of rotary table to last decades. However, if you need a stiffer hold, oil hydrostatic could be the better choice. And in other cases, mechanical-bearing rotary tables could be best. All in all: It depends.

But if you want to know more about rotary tables and which would be the right choice for your application, contact the experts at ABTech. We will ensure you get exactly what you need.
