BallDrive NC Rotary Table

RBS-160R

"RBS series" Tsudakoma uniquely developed 'BallDrive' realizes no backlash and extremely small aging deterioration.
Clamp-less machining because of "BallDrive" high rigidity can minimize cycle time. Indexing speed is two times faster than conventional model.

Features

  • High Speed Indexing
  • No backlash, High rigidity
  • Save energy by high transfer efficiency
  • Extremely small aging deterioration
  • Adopt high response clamp mechanism (newly-developed)

Application

  • High precision parts machining
  • Complex-shape parts like Turbine-blade by high efficiency machining
