TC Series

Roller Cam Rotary Table - THE RELIABLE CHOICE

TC145-110

The TC Series is a high torque, zero backlash gear roller cam rotary table that is the preferred fourth axis for CNC machine tools. Its zero backlash, high torque, integrated hydraulic brake and zero maintenance make it one of the most popular products in CNC manufacturing. Siemens and Bosch-Rexroth motors and drives are available.

The TC rotary table minimizes drive wear, keeping it virtually maintenance-free throughout its service life, and maintains its original precision.

TC145-110 Highlights

  • Backlash-free. The roller and cams are driven by a double preloaded rolling contact. No backlash during forward and reverse rotation, which further enhances the precise and stable characteristics of the roller cam.
  • Long service life. Roller cam drive. Wear and tear will reduce. Long service life.
  • Extremely rigid, integrated turret design. Multiple rollers engaged with the camshaft increase rigidity during transmission.
  • High transmission efficiency, no temperature rise at high speeds, minimal thermal fluctuations
  • Maintenance free. Due to the low wear, maintaining the original accuracy for a long time (3-5 years without mechanical maintenance).
  • Braking performance: positioning during braking remain within 0.002 mm. High precision machining possible. Wear resistant brake parts. No shifting during braking. High durability.
