SWIVEL ROTARY TABLES

DYNAMIC MEETS PRECISION

The new two axis swivel rotary tables with synchronous drives for high dynamic applications are the result of long-term experience gained in the conception and design of torque motors produced by CYTEC Zylindertechnik GmbH.

CYTEC's new direct-drive rotary table series expanded its ability to find solutions for equipping high-capacity machining centers. Workpiece carriers can be tailored to meet the individual needs of a machine manufacturer, because of our interchangeable parts concept and the in-house production at the company’s headquarters in Jülich.

A comprehensive service concept ensures the quick exchange of system components, should servicing be required. The new rotary tables are available in two series, HT torque for high torque applications and HS speed for high speeds. Both are direct-drive and can hold a rotary feedthrough. They can be used to feed up to ten channels with media such as hydraulic, coolant or air supply.

A media interface can be integrated into the tabletop via plug-and-play, to activate chucks or clamping devices. This eliminates the need for complex special solutions, as are often necessary for smaller round tables. High clamping torques facilitate the stiff and precise positioning of the workpiece for demanding processing scenarios. In addition, the entire series is available both with a hydraulic as well as a pneumo-mechanical system.

The user-friendly design of the torque motors makes a quick change of the components possible in a service event. The rotary table is enclosed in a disposable cartridge and can be installed by trained installers as one compact unit. This way a replacement will take only a few hours. Expensive downtimes are reduced to a minimum.

FURTHER INFORMATION

Modular drive package

For each application the appropriate drive concept can be configured:

for the swivel axis three strong HighTorque drives are available (light, medium, heavy for load weights from 500 up to 1.000 kg), and two rotary drives for various machining purposes. For the rotary axis you can select either a high dynamic positioning unit or a highspeed module (up to 1.000 rpm) for mill-turning applications.

Interfaces

  • Power connections:
    • Motors swivel axis (A axis)
    • Motors rotary axis (C axis)

  • Sensor ports:
    • Temperature monitoring
    • Vibration monitoring
    • Angular measuring devices
    • Tool measuring unit
    • Leakage
  • Hydraulic ports:
    • Tool clamping system
    • Axis clamping

  • Pneumatic ports:
    • Blocking air axes
    • Blocking air/compressed air tool measuring

  • Cooling ports:
    • Motors swivel axis (A axis)
    • Motors rotary axis (C axis)
Supply connections on the left drive of the swivel axis (A axis)
Supply connections on the right drive of the swivel axis (A axis)

Compact design

The rotary table is characterised by compact design:

  • the dimensions of the swivel flanges are reduced to the minimum possible diameter and length
  • due to the minimised size the table can be implemented from the front side into the machine body very easily

APPLICATION ­EXAMPLES

The high dynamic rigidity, combined with compact design and high capacity drives enable various dynamic high speed cutting processes. Heavy cutting and rough machining under high loads is an important feature of this new generation of rotary tables.
