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 hydrostatic rotary tables from ZOLLERN impress with their durability and a high concentricity and axial runout accuracy. Thanks to the ZOLLERN bearing clearance compensator, the optimal pocket pressure is set automatically and independently of production tolerances. The freedom from friction at low speeds prevents slip stick and therefore allows maximum positioning accuracy.

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.

Cameron rotary tables range from 27 1/2 in to 60 1/2 in and feature a large oil capacity that adds to the unit"s durability. The rotary table includes a forged-steel fabricated housing and a heat-treated forged-steel turntable. Each rotary table is supplied with spiral-bevel, induction-hardened gears and two independent ratchet-type locks, with lever access from the top to lock the table in position.

Our direct drive rotary tables provide high torque and are easy to integrate. They contain high-energy magnets in a simplified mechanical design and drive loads directly without the need for a transmission mechanism or gearbox. It allows customers to build them right into a drive system for flexible placement and integration with cooling pipes and cables, for example.

We supply a wide range of frameless motors, and our adjustable motors include an optical encoder, scale, bearing and housing. Given our selection, it can be challenging to choose the best direct drive motor for your project. Our engineers prefer to help you find the right rotary table for your requirements.

Our most popular rotary motor, the AXD series is characterized by a slim, compact "pancake" design with high peak and continuous torque despite the motor"s quite small form factor.Direct drive and brushless motor

The ACD series is a set of ironless rotary tables. This motor is cogging-free and features high-resolution optical encoder feedback and low speed variability. This permanent magnet motor is equally suited for either low or high speed applications.Zero cogging coreless motor

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.

To reach the full potential of our flexible EDH-series we created additional sizes, specifically designed for heavy-duty applications. These rotary tables reach table plate diameters up to 3.000 mm by default. Individually customized designs can reach up to 10.000 mm in diameter and move close to 100t. They are available upon request, please contact us for further information.

The heavy-duty rotary tables are not only the basis for our Multitooling-System and Rotate-Lift-Units, they are also used at large scale casting applicatons, interior production, glass industry and manufacturing of large gears and engines.

There is no length limit for linear motors. This is because the engine tracks can be connected to each other in sections. The linear rails can also be connected to each other. The linear scale for donor repatriation can be delivered in large lengths as well. Therefore, linear engine applications can be built up to 20m or even longer.

Linear Motors can be used in cleanroom environments. In fact, many front-end semiconductor applications have linear motors in use. In wafer manufacturing plants, high-precision lithography machines, for example, use linear motors in XY positioning tables with very high accuracy (nanometer resolution) and submicron accuracy in cleanroom classes according to ISO 2.

The DGII Series is a line of of products that combine a high rigidity hollow rotary table with an AlphaStep closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads.

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.

With over ten years of expertise in the field of direct drive torque motors, WEISS often designs and develops out of the logical response to changing market requirements and customer demand. This was the case with the TO1300 as a client’s concrete custom requirements stipulated a high mass inertia of 160 kgm2 and a large index increment of 45° with fast cycles−namely an index time of 0.21 seconds with a dwell time of 0.29 seconds.

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:

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.

Years ago, before I learned CNC, I owned a Phase II 8″ horizontal/vertical rotary table that I purchased from Kap Pullen’s Getmachinetools.com store. He has them at a good price, BTW, and he’s a darned nice fellow to deal with as well as being a frequent HSM contributor. Anyway, its a nice little table, but I hadn’t done a whole lot with it for quite a while after purchasing it. As is so often the case, one day, a project landed on my doorstep and I was glad to have it.

Before I could get started, however, I had to make some accessories for it. Basically, I needed some T-Nuts to fit the table, as well as a little fixture that makes it easy to hold a plate up off the table through a hole in the center so you can machine it. The latter, what I call a “plate machining fixture”, was inspired by something similar I saw the Widgitmaster of CNCZone fame using to make Dremel clamps for his mini-router:

I turned the round spigot using the 4-jaw on the lathe. I’m making the fixture out of MIC-6 aluminum plate, which is pre-ground very flat on the sides. This is a 5 inch by 3 inch piece. I’ve clamped it to the rotab using my T-nuts and the regular mill clamps and step blocks. It is sitting on parallels to make sure I don’t cut into the table. You can also see how I’ve clamped the rotary table to the mill table using a big cast iron V-block I have. You can never have to many blocks with precision faces hanging around!

Having a 4-jaw chuck on your rotary table is mighty handy! Because it’s a 4-jaw, you can dial in the workpiece by adjusting the jaws until it is perfectly concentric with the table’s axis of rotation. The best way is to make an adapter plate that attaches to the back of the chuck in the same way that your lathe does so you can exchange lathe tooling with the rotab. Here is an example:

For the example, the chuck is threaded onto the adaptor plate, and then the holes in the adapter plate’s flange are used to bolt down to T-nuts on the table.

In my case, I bought a 4-jaw from Shars brand new, and simply drilled some through-holes in the chuck to mount to the table directly without an adapter plate:

First, you want to make sure your part is properly centered on the table. To do that, I clamp the table down on the mill table (no special place is needed), put my Indicol indicator holder on the mill spindle, and find some round feature on the part to indicate on. For example, on the plate milling fixture above, indicate on the round boss, or on the center hole. Spin the table and bump the part in until spinning the table doesn’t move the indicator.

Second, locate the center of rotation directly under the mill spindle. You can simply use the X and Y table handwheels to do this. Use that Indicol to indicate off of a circular feature you want centered under the spindle. Turn the indicol around on the spindle and adjust the handwheels until the indicator stays put relative to the spindle position. A Blake Coaxial indicator will make this last even simpler.

When you’re rounding partially by cranking a part around on the rotary table, it’s really easy to go a little too far and screw things up. The answer is to drill the end points to make the exact stopping point on the rotab a lot less sensitive:

Centering with a Blake indicator is really fast, but what if you don’t have a Blake, or worse, what if your mill is too small to accomodate one? Here is a nice solution I found on a German site. This fellow has made an ER collect fixture for his rotary table, and has taken care that when installed on the table, the axis of the collet is aligned with the table’s axis. He can then place a dowel or other straight pin in the collet and line up until it will go into a similarly sized collet on the spindle. Nice trick! It’s similar to how Widgitmaster showed me to align a drill chuck on a QCTP to the lathe centerline with a dowel pin held in the lathe chuck.
