The ABRT series precision rotary tables from Jena Tec utilise robust high precision roller axial bearings with an air bearing in the horizontal axis for smooth, precise rotary motion. The air bearing principle offers a compact overall height of only 100mm with a cost effective bearing solution and high geometric accuracy. A hollow shaft design means that centralised services for pnuematic or hydraulic clamping can be provided easily. Units can be supplied in either manual or CNC format with a standard range of torque motors offered.
The addition of a hydraulic clamp mean that the ABRT system is suitable for heavy machining in a stationary position as well as positioning, and light dynamic machining. Typical applications include inspection, non-contact machining and CNC milling as well as retrofit or modular use with manual boring or milling machines supplied with a DRO system.
