Direct Drive Rotary Tables

Boost productivity and increase accuracy with GSI Direct Drive Rotary Tables! The GSI DNC-400 is ideal for high-volume and aerospace manufacturers doing 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. In addition, the direct-drive motor eliminates backlash and delivers high servo stiffness. Because there's no mechanical gearing, the DNC-400 has fewer parts to wear.

The table delivers 200 RPM rotational speeds, 0.0004 in. spindle runout, and 515 PSI hydraulic pressure. Maximum torque is 590 lb-ft, and brake torque is 1,844 lb- ft. Superior clamping torque ensures smooth machining without deflection under heavy loads.

The DNC-400 has a 15.75" table diameter and boasts a maximum horizontal loading capacity of 1,100 lb (661 lb vertical loading capacity). The table weighs 661 lb. Check out GSI’s Direct Drive rotary tables – they’re easy to install and operate and provide high accuracy and value!
