Direct Drive Rotary Table Delivers High Speed, High Torque, and Increased Accuracy

The GSI DNC-400 direct drive rotary indexing table from CNC Indexing & Feeding Technologies 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. • Table diameter (mm / in.)- 400 / 15.75 • Center height vertical (mm / in.)- 250 / 9.8 • Overall horizontal height (mm / in.)- 320 / 12.6 • Overall vertical height (mm / in.)- 460 / 18.1 • Net weight (kg / lb)- 300 / 661 • Type of motor- Fanuc D800/250is • Motor rotation-Continuous • Maximum RPM- 200 • Spindle runout (mm / in.)- 0.01 / 0.0004 • Stall torque (N-m / lb-ft)- 320 / 236 • Maximum torque (N-m / lb-ft)- 800 / 590 • Brake Torque (N-m / lb-ft)- 2500 / 1844 • Hydraulic pressure (kg/cm 2 / PSI)- 35 / 514.5
