TD Series

DD Motor Rotary Table- FAST, STRONG AND PRECISE

TD170-135

TD series adopts Direct Drive R motor technology, which can achieve the working torque similar to that of worm gear and roller cam (TC series). It has higher speed, can increase the working torque and achieve high dynamic response and accuracy.  Gapless transmission, high precision, high speed and improved processing efficiency are key advantages of TD series. 100% backlash-free as well as almost no wear increase the reliability of the rotary table and make it versatile.

TD170-135 Highlights

  • Motor drive with high torque and backlash-free gear. Wear-free and highly precise.
  • Direct drive, no gear reduction, high speed, improved machining efficiency.
  • Equipped with high precision encoders for high accuracy positioning.
  • Double-piston brake design with double braking force for heavy cutting.
  • Self-locking protection in case of power failure to prevent a sudden power failure during processing from causing a crash.
  • Compact and more flexible arrangement, saves space in the machine.
  • High precision positioning, fast dynamic response and zero backlash improve the surface finish of machined parts. Excellent performance when high surface finish is required.
