In modern precision engineering, reducing setup times and enabling automated, continuous machining are key to staying competitive. As an authorised partner of Kurt Workholding, Core Mach Group is excited to highlight Kurt’s latest breakthrough in 5-axis clamping technology: the Kurt PFA620 5-Axis Pneumatic Vise.
Designed specifically for modern multi-axis machining centers, the PFA620 combines shop-air actuation with a compact footprint to deliver maximum rigidity, speed, and 5-sided part access.
Here is how the new Kurt PFA620 Air Vise is transforming 5-axis operations and lights-out machining:
1. Air Actuation Meets Manual Full-Stroke Adjustment
Unlike conventional pneumatic vices that limit jaw travel, the PFA620 features manual full-stroke adjustment using a hex screw and handle. Machinists can rapidly adjust to different raw stock dimensions on the fly, while the ¼-inch pneumatic stroke applies consistent, repeatable clamping pressure.
2. Built for Seamless Lights-Out Automation
Whether integrated with a robot cell, a machine tool controller, or a basic pneumatic switch, the PFA620 is built for automation. Bottom-ported pneumatic connections allow internal air routing straight through the base or rotary union, eliminating messy external air lines and keeping the work envelope clear for 5-axis tool paths.
3. Snap-On, Tool-Less Quick-Change Jaws
Minimising changeover time between jobs is vital. The PFA620 utilises quick-change jaws that snap on and off without requiring tools. Machinable, serrated and dovetail jaw options ensure optimal grip regardless of your material or part geometry.
4. 2,000 lbs of Clamping Force from Standard Shop Air
Despite its compact design, this pneumatic powerhouse delivers up to 2,000 lbs of clamping force at 110 PSI. This robust holding power eliminates vibration and workpiece distortion during high-speed, heavy-duty 5-axis milling.
5. Superior 5-Sided Machining Clearance
With a 3.5-inch elevated rise, the PFA620 elevates the workpiece off the rotary table platter, giving cutting tools complete 5-sided clearance without risk of spindle collision.
