Description

This CLB pneumatic booster CNC vise is an efficiency-focused automatic workholding fixture for mass CNC production. The entire frame is forged from solid alloy steel with multiple stress relief cycles and full hard precision grinding, paired with a built-in air hydraulic booster unit. It separates fast idle travel and high-pressure clamping to eliminate repetitive screw cranking work of manual vises, ideal for unmanned and high-throughput workshop processing.
  1. Built-in Air Hydraulic Booster Force Amplification System
    Standard factory air supply converts low input air pressure into up to 6000kg rigid clamping force. Steady uniform compression avoids workpiece shifting during heavy stock removal milling; an external adjustable pressure knob allows output force tuning to prevent thin part crushing or insufficient grip.
  2. Red Ergonomic Quick Travel Manual Handle
    Independent red quick-release handle controls full idle jaw stroke in one single pull, moving jaws rapidly to approach workpieces without rotating the heavy load screw. Only air booster pressure locks the workpiece tightly, slashing fixture loading/unloading cycle time by over 70% compared to traditional manual vises.
  3. Integral Forged Solid Alloy Steel Anti-deformation Body
    One-piece thick solid steel blank construction eliminates casting shrinkage and deformation flaws of cast iron vises. All mounting base, jaw contact and sliding guide surfaces undergo precision grinding to maintain long-term parallelism and flatness after thousands of clamping cycles.
  4. Ultra-long 250mm Maximum Opening Stroke
    Extended movable jaw travel accommodates large-size thick metal blanks that standard 6-inch vises cannot hold. Fixed jaw mounting holes support custom soft jaw installation for irregular, thin-wall and special-shaped workpiece clamping.
  5. Compact Integrated Air Circuit Layout
    Air inlet port and pressure regulating valve are integrated on the rear power unit without external bulky accessories. Standard T-slot base mounting holes enable fast installation on all mainstream vertical CNC machining centers for automatic batch production lines.
