TTD-255H
NC Tilting Rotary Table (0.001°)
TTD-255H
NC Tilting Rotary Type
- 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°.
