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
