Zero-point clamping system in combination with hook clamping flange 63707B for set-up-time-optimised clamping during cutting and non-cutting machining.


The surface-mounted clamping module has high holding, pull-in and locking forces. This is opened pneumatically (1) and mechanically locked through spring force. To achieve the specified pull-in and locking forces, it must be briefly retensioned pneumatically (turbo) (2). Subsequent uncoupling of the pressure lines is possible at all times (module is tensioned pressure-free).
Use of the pneumatic pressure booster 6370ZVL is recommended.
The clamping module with blow-out and support control has three connections:
1x pneum. opening (1) / 1x pneum. retensioning (turbo) (2), 1x pneum. blow-out and support control (3). (The pneumatic blow-out and support control can optionally be connected.)
* Please observe the installation instructions.
