BallDrive NC Tilting Rotary table

TBS type (Ø160)

Followed by "RG type", Tsudakoma introduces BallDrive NC tilting table "TBS type".
It realizes no backlash and extremely small aging deterioration.
Clamp-less machining because of BDS high rigidity can minimize cycle time.

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)
  • Space saving

Application

  • High precision parts machining
  • Complex-shape parts like Turbine-blade by high efficiency machining
  • 5-axis complex machining
  • For electric components like smart phone
