The DDRT-260 rotary table is designed for operation on Mori Seiki's DuraVertical 5060 and 5080 and NV4000 DCG vertical machining centers. It offers stable, high-efficiency four-axis machining with powerful clamping and high-precision indexing, the company says.

The rotary table uses a direct drive motor to drive table rotation instead of a servomotor and worm gear. Equipped with a high accuracy encoder that is mounted directly to the spindle, the unit provides improved positioning accuracy over gear-driven motors and eliminates backlash, positioning delays and costly maintenance requirements. Additionally, the rotary table is capable of rotating 180 degrees and reclamping in approximately 0.4 seconds with a rotational speed of 150 rpm.

With a table diameter of 260 mm (10.2"), the rotary table has a 55-mm (2.17") through hole that allows for pneumatic or hydraulic clamping and uses 200-mm diameter (7.9") cross roller bearings to achieve high rigidity, high precision guides. The rotary table also offers an indexing precision of ± 6 seconds and a maximum horizontal loading capacity of 400 kg (800 lbs).
