Weiss North America Introduces TO1300 Rotary Table
POSTED 08/14/2013
Willoughby, OH - Industry leading specialist for rotary tables and automation WEISS North America, Inc. (Willoughby, OH) has recently introduced its’ largest torque rotary table to date−the TO1300. An extension of its’ established smaller direct drive tables (TO150, 220 and 750); the TO1300 combines the advantages of direct drive with high torque – allowing larger scale application scenarios that require high-speed and high-accuracy to be fully realized.
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.
DYNAMIC DEMAND / DESIGN DIRECTIVE:
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.
Notably, it has the ability to cover a significantly more versatile range of tasks−including repeat use through reprogramming which allows customers to cultivate value added potential.
TO1300 TORQUE ROTARY TABLE:
- User-programmable direct drive
- Medium loads
- High speeds of up to 80 rpm
- Peak torque of up to 26,600 Nm
- Non-wearing
- Water cooling available for high continuous output
- Absolute measuring system
- Overload-protected through temperature sensor
- Non-contact labyrinth seal with air seal
TO1300 CUSTOMIZATION:
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:
Don't Miss These Industry-Leading Events!
- Drive torque variable through different motor lengths
- Rated power variable through water cooling option
- Table speed variable through various combinations of motor/bearing/control technology (field weakening)
- Precision variable through optical or magnetic measuring system
- Method of functioning variable through incremental or absolute encoder
RESULTS/CONCLUSION:
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.
