WEISS North America, Inc. has introduced its largest torque rotary table to date, the TO1300. "Featuring a 1,300 mm footprint, 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," said a company spokesperson. "Additionally, the TO1300's drive operates predominantly without mechanics or gearboxes."
WEISS designed the TO1300 in response to a client's custom requirements. Requirements included 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," said the spokesperson. "Due to their gearing ratio, however, these tables do not 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 and is virtually free of backlash. The table is low wear and capable of delivering the desired dynamic performance requirements. It also has the ability to cover a versatile range of tasks, including repeat use through reprogramming."
Features of the TO1300 torque rotary table include:
- 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.
Customers can customize the rotary table to their individual requirements. For example, they can make a modular selection between bearings, encoder and motor, and thereby alter the following table characteristics:
- 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.
WEISS also offers a variety of sizes for the TO series indexing tables. Each TO model is also available in a version with a cleanroom certificate.
