NC Tilting Rotary Table


NC Tilting Rotary Type

TTD-255H NC Tilting Rotary Type

  • Information
  • Specification
  • Dimension
  • Adopting Hydraulic Swelling Surrounding Clamping System, to enlarge clamping force (about other models' 1.2-1.4 times), and ensure heavy-duty continuous cutting.
  • Can do tilting angle machining.
  • The feature of wear resistant alloy Dual-Lead Worm Gear is high mechanical efficiency of Power transmission, high indexing accuracy and easy adjusted on the backlash.
  • Driven by the Servo Motor. Efficiently in position, high accuracy, low noise and suitable for any angles working piece.
  • It can be connected with CNC machine as a 5th Axis ( 5th Axis or 4+1Axis).
  • It can be connected with single axis controller to connect with CNC machine to perform tilting angel machining (4+1 Axis).
  • Minimum indexing degree: 0.001°.
  • Tilting range: ±110°.
