Bore clamp
double acting, for bore hole diameter 7.8 - 17.7 mm
max. operating pressure 250 bar
The bore clamp is a double-acting pull-type cylinder. An exchangeable clamping bushing is fixed to the piston.
The four segments of the clamping bushing are radially expanded with spring force by a pyramid-shaped clamping bolt. Thus the expansion force is always the same and independent of the hydraulic clamping pressure.
The workpiece is also held without hydraulics by means of the expanded clamping bushing. Both pull-down of the workpiece and unclamping of the clamping bushing are hydraulically controlled.
Connecting the positive air pressure protection, the clamping bushing is protected against swarf and coolants.
In the hardened support surface for the workpiece there is a bore hole for the pneumatic seat check.
