Four zero point clamps in one square plate – complete 4‑station pallet changing system on a single base
Ultra‑low profile – only 48 mm height, preserves Z‑axis travel for tall workpieces
Square 380×380 mm footprint – matches standard CNC pallet sizes and tombstone fixtures
High repeatability – ±0.005 mm (0.0002″) per station for consistent pallet registration
Massive total pull‑down force – 220 kN (49,456 lbf) secures even the heaviest parts
High max. air pressure – 1.2 MPa (174 psi) for industrial‑grade reliability
Precision ground surface – entire top surface flat and parallel for accurate fixturing
Hardened steel construction – designed for high‑cycle automated production
Multi‑pallet CNC systems – four independent clamping stations for sequential machining
Tombstone fixtures – mount directly on HMC tombstone faces for 4‑side workholding
5‑axis machining centers – low profile and square shape ideal for rotary table mounting
Automated production cells – robotic pallet changing across four stations with zero‑point repeatability
High‑mix / high‑volume manufacturing – quick changeover between different fixture plates
Heavy and large workpieces – 220 kN total pull‑down distributes clamping force evenly
EDM and precision grinding – four registration points provide exceptional stability
Complete 4‑station solution – no need to align and mount four separate single clamps
Lowest profile 4‑station system – 48 mm height keeps workpiece close to machine table
Factory‑set station spacing – eliminates measurement errors and reduces setup time
Manifold air distribution – single air connection activates all four stations simultaneously
Precision ground reference surface – verified for flatness and perpendicularity
Pneumatic only – no hydraulic power unit required, clean and simple
Automation ready – consistent zero‑point locking for robot‑tended pallet systems
Custom configurations – mounting hole patterns available upon request
