BallDrive NC Tilting Rotary table
TBS-160
Followed by "RBS type" Tsudakoma introduces BallDrive NC tilting table "TBS type".
It realizes no backlash and extremely small aging deterioration.
Clamp-less machining because of "BallDrive" 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
