Assign Add to Favorites Products Font Size: Rotary table for high efficiency four axis machining May 2008 | Mori Seiki has released DDRT-260 rotary table. Designed for operation on Mori Seiki's DuraVertical 5060 and 5080 and NV4000 DCG vertical machining centers, the DDRT-260 offers stable, high efficiency four axis machining with powerful clamping and high-precision indexing. Mori Seiki's DDRT-260 uses a direct drive motor to drive table rotation instead of a servo motor 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 DDRT-260 is capable of rotating 180° and reclamping in approximately 0.4 seconds with a rotational speed of 150 rpm. With a table diameter of 260 mm (10.2 in.), the DDRT-260 has a 55 mm (2.17 in.) through hole that allows for pneumatic or hydraulic clamping and uses ø 200 mm (7.9 in.) cross roller bearings to achieve high rigidity, high precision guides. The rotary table also offers an indexing precision of ± 6 seconds (± 0.0016 degrees) and boasts a maximum horizontal loading capacity of 400 kg (880 lbs). Additional sizes of the direct drive rotary table will be available in late 2008. www.moriseiki.com Products Archives privacy || home || contact us || rogers publishing limited
