Design: With central lock, blow-out, support control and opening control. Application: Zero-Point Clamping System for automation solutions. Set-up-time optimized, clamping during cutting and non-cutting machining. Note: Central lock with pneum. cleaning function of support surfaces. Fastening and installation of the pull-stud by means of DIN ISO countersunk head screw M12. Opening control (unclamp sensing): Dynamic pressure with opened clamping module, flow-through with locked clamping module. Support control via the blow-out function: Dynamic pressure with supported interchangeable pallet. The installation clamping module is opened hydraulically and mechanically locked through spring force. Subsequent uncoupling of the pressure line is possible at any time (module is clamped at normal pressure).
support control (pneum.). (Studs Sold Separately)
The clamping module has four connections: 1 = hydr. opening 3 = pneum. Blow-out and support control 4 = pneum. Opening control inlet (unclamp sensing) 5 = pneum. Opening control outlet (VENT) Dimensions:
