Key Features
-
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
Application Scenarios
-
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
