Application: Zero-Point Clamping System for set-up-time-optimised clamping during cutting and non-cutting machining. Note: The hydraulic clamping module without clamp assist, single acting has high holding, pull-in and locking forces. This is opened hydraulically (1) and mechanically locked through spring force. Subsequent uncoupling of the pressure lines is possible at all times (hydraulic module clamps without clamp assist, single acting). The clamping module with blow-out and support control has two connections: 1x hydr. opening (1) / 1x pneum. blow-out and support control (3). (The pneumatic blow-out and support control can optionally be connected.) Dimensions:

Application: Zero-Point Clamping System for set-up-time-optimised clamping during cutting and non-cutting machining. Note: The pneumatic clamping module has high holding, pull-in and locking forces. This is opened pneumatically (1) and locked mechanically through spring force. To achieve the specified pull-in and locking forces, it must be briefly retensioned pneumatically (clamp assist) (2). Subsequent uncoupling of the pressure lines is possible at any time (module remains clamped after being depressurized). 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.) Dimensions:
