SPANNTOP combi pull-back: with a fixed end-stop for chucking work and a through-bore for bars
- Axial draw force against the end-stop, which stabilizes the clamping [important for short clamping lengths]
- Little inertia loss
- Extremely rigid
- Optimal holding power
- Excellent concentricity after clamping head change
- Simple mechanics, results in better power conversion
- Clamps work pieces with short clamping length
- Converts to full functional "bar chuck" when end-stop plate is removed
