BallDrive NC Rotary table

RBS type (Ø160)

The new technology, Tsudakoma Ball Drive System is adopted.
It enables high indexing speed which is two times faster than conventional model and super productivity with top quality thanks to no backlash and high rigidity.

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

  • Mass produced small parts machining
  • For Compact machining Center
