BallDrive NC Tilting Rotary table
TBS type (Ø130)
TBS -Tilting Rotary table with Ball Drive system- models feature positive drive without backlash through constant pre-loaded pressure on the Ball Cam Shaft and Turret, which insures minimal wear through the long life of the drive system. The highly rigid Ball Drive System allows machining without clamping and thus minimizes machining 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
- 5-axis complex machining
- For electric components like smart phone
