Description
Version:
Schunk GZB-S with seal.
Tight against coolant up to 80 bar.
Flexible length pre-setting possible through movable intermediate piece.
Sealed (rubber plug).
Tight against coolant up to 80 bar.
Flexible length pre-setting possible through movable intermediate piece.
Sealed (rubber plug).
Application:
- For drilling, reaming, milling, and tool sharpening.
- Very high flexibility due to reduction in clamping diameter.
- High torque guarantees a greater metal removal rate than with direct clamping.
- Concentricity ±5 µm (system accuracy at 3×D).
- Concentricity ±2 µm (for reducing adapter).
- Can be used in all commercially available hydraulic chucks.
