Key Features
-
Three zero point clamps integrated into one round plate – complete 3‑station system on a single base
-
Low profile design – only 53 mm height, preserves Z‑axis clearance for tall parts
-
Round 326 mm diameter – ideal for rotary tables, indexers, and 4th/5th axis applications
-
High repeatability – ±0.005 mm (0.0002″) per station for consistent pallet registration
-
Triangular clamp arrangement – three-point contact provides superior stability and eliminates rocking
-
Total pull‑down force – 165 kN (37,092 lbf) secures workpieces evenly across three points
-
High max. air pressure – 1.2 MPa (174 psi) for demanding production environments
-
Precision ground surface – entire top surface flat and parallel for accurate fixturing
Application Scenarios
-
CNC rotary tables and indexers – round shape matches typical rotary table mounting patterns
-
4th and 5th axis machining – three‑point clamping provides exceptional stability during complex contouring
-
Triangular or irregular pallets – 120° clamp spacing adapts to non‑square fixture plates
-
Automated pallet systems – three registration points ensure proper orientation every cycle
-
Large diameter workpieces – 326 mm span accommodates oversized parts on round fixtures
-
EDM and precision grinding – three‑point contact eliminates workpiece tilt and vibration
-
High‑speed machining – 165 kN pull‑down force dampens chatter in aggressive operations
Why Choose JIYAN
-
3‑point stability – triangular clamp arrangement prevents rocking better than 2 or 4 corner clamps
-
Rotary table optimized – round form factor matches standard CNC indexer bolt circles
-
Factory‑set clamp positions – no alignment errors or spacing measurements needed
-
Low profile for 5‑axis – 53 mm height keeps part close to rotary axis centerline
-
Precision ground reference surface – each unit verified for flatness and parallelism
-
Pneumatic only – no hydraulic power unit required, clean and simple installation
-
Manifold air distribution available – single air connection activates all three stations
-
Automation ready – consistent zero‑point locking for robot‑tended cells
