The NC combines robustness and durability with the advantages of a user-programmable rotary table that offers a high level of torque. This is made possible by the latest generation of servo motor drives with integrated absolute value encoder and a drive cam with constant pitch. For applications requiring extreme precision, we offer the additional encoder option, which is connected directly to the drive cam.The further refined NC range has been given a significantly larger central opening. The cables and hoses can now be guided downwards directly through the table or through the practical side channel. We have achieved this while maintaining the same external dimensions as its predecessors – which have now been replaced by the new range.

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.

Corporate Profile: An integral part of the Weiss global network, Weiss North America (ISO-9001 Certified) leverages over 45 years of reliable world-wide expertise to comprise an integrative, customer-specific approach to its vast array of electromechanical products. Our 100% vertical range of manufacturing ranges from rotary indexing tables, handling systems, and linear assembly systems−providing flexible technology for turnkey solutions that incorporate electronics, mechanical systems, software, and comprehensive engineering support. This enables us to provide pre-installed, intelligent, and highly convenient solutions for the entire field of kinematics.

We have given the new TC range a significantly larger central opening for the 120 – 320 sizes. The cables and hoses can now be guided downwards directly through the table or through the practical side channel. We have achieved this while maintaining the same external dimensions as its predecessors – which have now been replaced by the new range.

Alongside automatic nest detection, with the new DriveCliq encoder option in connection with the EF2 rotary table control system we now also offer cam switching mechanism functionality, which permits a significant increase in the effectiveness of the overall system.

By the way: we also offer automation options for cleanroom environments. If you would like to receive information and offers relating to the Cleanline versions of our rotary tables

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.
