Benefits:
Large through-hole: This allows for the machining of long bars, pipes, or workpieces with significant internal diameters.
Hydraulic actuation: This provides precise control over clamping force, ensuring a secure grip on the workpiece without damage.
Three jaws: These jaws evenly distribute clamping force around the workpiece, providing stability and preventing distortion.
High clamping force: This enables the machining of challenging materials and complex geometries.
Repeatability: Consistent clamping ensures accurate and repeatable machining results.
Versatility: The large through-hole allows for a wide range of workpiece sizes and shapes to be machined.
