The GSI DNC-400 direct-drive rotary indexing table is suited for high-volume and aerospace manufacturers performing high speed, high-accuracy contouring operations. Compared to tables using a servomotor and worm gear, this direct-drive table offers higher accuracy, faster rotational speeds and higher torque, the company says. In addition, the direct-drive motor is built to eliminate backlash and deliver high servo stiffness. Without mechanical gearing, the table has fewer parts to wear.
The table delivers 200-rpm rotational speeds, 0.0004" spindle runout and 515-psi hydraulic pressure. Maximum torque is 590 foot-pounds, and brake torque is 1,844 foot-pounds. The clamping torque is said to ensure smooth machining without deflection under heavy loads. The table has a 15.75" table diameter and offers a maximum horizontal loading capacity of 1,100 lbs (661-lb vertical loading capacity).
