The Key Advantages;
Application
In situations where the enhanced motion performance of thin film air bearings are advantageous. Table sizes from 500mm to 1500mm diameter for inspection, test and metrology applications.
Construction
The principle castings are made from high grade established iron. Light duty covers enclose the gear-reduced friction drive, which is only operative during air flotation.
Bearing
High load thin film air thrust bearing with a preloaded precision rolling bearing on the rotary axis. By design the air bearings are self-cleaning during operation.
Clamping
Light duty metal-to-metal system for inspection type applications.
Measuring Systems
High precision angular encoders set on axis with DRO or NC systems.
Motors
Various motor types available

UNION rotary, traversing, and tilting tables are predominantly suitable for use on floor-type boring mills and/or traveling-column machines. However, they can also be operated separately with self-contained controller and self-contained operator console. The PDV 10 with a machining torque of 12.5 kNm ensures turning operations on large cylindrical parts in association with traveling-column machines and suitable turning tool adapters. So, supplementary turning operations can be performed.
