Pneumatic Quick-Change Pallet Clamps are high-force workholding solutions designed to replace conventional hydraulic clamping systems in pallet-based machining. Operating through a piston-driven, steel ball locking mechanism, the system securely seats the pallet against a precision taper, ensuring high rigidity and repeatable positioning.
The integrated mechanical lock maintains clamping force without continuous air supply, eliminating the need for hydraulic power packs and reducing overall system complexity and energy consumption. Despite a compact design, the clamps deliver comparable force to hydraulic systems, making them ideal for retrofits and hybrid setups.
The system consists of a pneumatic clamp unit and interchangeable receiver blocks mounted on the fixture base. It achieves locating repeatability up to 3 microns, removing the need for frequent alignment checks. Built-in air blow ports ensure clean seating, while optional seat-check functionality verifies proper engagement.
Available in multiple force ratings (4 kN to 16 kN), the clamps support flexible configurations using datum and guide clamp combinations for precise kinematic constraint. Receiver blocks are fully compatible with both pneumatic and hydraulic systems, enabling shared pallet designs across applications.
Key Advantages:
• Eliminates hydraulic infrastructure
• High rigidity and precision
• Compact and energy-efficient design
• Shared pallet compatibility
• Reliable mechanical locking for safety
