Rotary indexing table use is widespread in automated assembly machinery and selecting the proper mechanism is essential for both maximizing performance and minimizing the cost of this critical component. This how-to-guide will explore two common devices that can be used for rotary indexing and give advice for proper selection. These two popular devices are cam indexing drives and servo rotary tables.

Cam indexers are a ubiquitous mechanism that have been used for rotary tables for many decades. They are a great fit for applications that will always index the same angle and that require high-precision positioning at a very reasonable cost. A cam indexer uses a mechanical cam to provide the motion control to position the load. A mathematical motion curve is machined onto the cam that provides extremely smooth and repeatable motion.

A cam indexer has two main modes of operation. One mode is referred to as “Cycle-on-Demand”. This indicates that the camshaft will be cycled one revolution at a time to advance the output one position at a time. This is typically achieved by using an inexpensive camshaft sensor package to detect camshaft position and a VFD to stop and start the motor. The camshaft dwell period offers a wide window for the camshaft to stop without affecting the position of the output. To cycle the indexer, a PLC gives a command to the VFD to accelerate the drive motor to a preset speed, the cam rotates one revolution indexing the output, a sensor sends an in-position signal to the PLC, and the PLC signals the VFD to stop the camshaft during the cam dwell position. The table will be in the dwell position for however long is necessary to complete the work at each station. The dwell time can range from a fraction of a second to several minutes or hours depending on the application. This combination allows very accurate positioning with an inexpensive drive system.

A fully programmable servo rotary table is another common option. There are two specific cases where a servo rotary table is advantageous. The first is when a flexible motion pattern is required. An example is two different products being run on one machine that each require different indexing patterns. The other situation that suits a servo indexer is when extremely fast positioning is required followed by a long dwell period. A cycle-on-demand cam indexer is limited by the need to accelerate the camshaft up to speed during the dwell period before output motion is started. There are practical limitations to how fast the camshaft can be accelerated so there will be a delay before motion is started. With a servo rotary table, the output rotates as soon as the servomotor starts moving. A practical example would be a load being indexed 90 degrees in 0.25 seconds. This is not difficult for a continuous cam indexer or a zero-backlash servo indexer, but a cycle-on-demand cam indexer may struggle with that motion. For quick servo indexing applications, a preloaded gear reducer with zero-backlash is critical to achieving smooth indexing motions with minimal settling time. A zero-backlash RollerDrive mechanism would be an optimal choice to achieve accurate positioning with great dynamic response.

For either style of indexer, application information including moment of inertia, indexing angle, indexing time, and dwell time is required. A reputable manufacture should then be able to properly size the rotary table for the application.

The Motion Index Drives RT Series Fixed Rotary Index Tables encompass a large range of sizes, ranging from our model RT100 up to our RT1250. In addition, special cam-driven devices can be custom made to order for your automation needs. RT Series Fixed Station Rotary Table are offered in a fixed number of stations or as a flexible turntable with a servo motor or standard AC brake motor with encoder. With the addition of Motion’s patented NANO Indexer Technology, the RT Series Fixed Station Rotary Table becomes the world’s most accurate barrel cam indexers.RT Series indexing tables are constructed with strength and reliability in mind. Robust design and components ensure this device will maintain precision in intense factory settings.

The bearing used must ensure a jerk-free and shock-free motion sequence of the rotary tables for the respective applications as well as high repeatability and high positioning accuracy in the end positions. High payloads are moved.

The Franke bearing elements LEZ used are precisely matched to the various loads and thus guarantee the required jerk-free and shock-free movement of the turntables. Due to the four-point system, the bearings easily absorb the occurring loads.

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.

To achieve rotary motion, Cross Company pairs a rotary table with a servo motor, drive and control to create a complete rotary actuation system.  This allows greater flexibility for your rotary positioner because you’re not tied to just one or two positions.  Some examples of rotary actuation that Cross Company has worked on recently include:Robotic cells which require precise rotary indexing for manufacturing stations

The rotary tables of our EDH-series have become an important key element for highly flexible automation applications. In contrast to our fixed-position EDX-series rotary tables, the flexible rotary tables are always equipped with an index cam with a constant pitch: resulting in an unchanged reduction ratio between the motor and the turntable plate. The partition is exclusively determined by the correspondence control unit of the servomotor.

Being flexible in use, the rotary tables of this type are particularly suitable for drive tasks in which the movement sequence has to be adapted in the production process, for example by new loads, new positions/end positions or travel directions. A typical example is the production of different vehicles on a production line, which makes flexible modification necessary in the production cycle.

Boasting a 1300 mm footprint, the TO1300 suddenly makes larger scale applications possible that previously seemed out of reach− as current direct-drive tables are relatively small and limited to a diameter of 750 mm. Additionally the TO1300’s high-tech drive operates predominantly without mechanics or gearboxes.

For challenging tasks of this nature, a mechanical heavy duty table is typically the logical choice. Due to their gearing ratio, however, these tables don’t fare well in service life calculations for use at such high speeds as the needle bearings simply suffer from too much wear.

The correct alternative is a direct drive; which inspired the development of the TO1300. With a direct drive, only one bearing is under load which is virtually free of backlash. The table is low-wear and easily capable of delivering the desired dynamic performance requirements.

Unique to the TO1300 is that customers can customize it to their individual requirements. For example; they can make a modular selection between bearings, encoder and motor, and thereby alter the following table characteristics:

Configured in a uniquely robust design, the TO1300 offers new possiblities for high-speed automation applications such as: lighting, automotive, cleanroom, small gear assembly, switches/sockets, and electronic components.

A specialist in automation, WEISS also offers many sizes for the TO series direct-drive rotary indexing tables; ranging from small to very large. Optimal solutions for specific application challenges can be achieved from the series wide range of options. Each TO model is also available in a version with a cleanroom certificate.
