Pneumatic Clamping Vise for Entry Into Automated Machine Tending

Collaborative robots and an abundance of integrators have made it easier than ever to implement automated machine tending. Many small to medium size manufacturers are making the investment into automation and seeing returns in less than six months.

The SCHUNK TANDEM PGS3 vise further supports this trend. Featuring reliable, quality construction, the TANDEM PGS3 reflects SCHUNK’s 75 years of experience at building quality components for the industrial automated manufacturing industry.

Low maintenance and precise

The pneumatically operated clamping force block SCHUNK TANDEM PGS3-LH 100 can be directly mounted on machine tables, dividing heads or VERO-S NSL 150 clamping stations of machining centers via an integrated flange. Its extremely compact design and square shape ensures optimum accessibility and enables a considerable stroke of 6 mm per jaw. With a clamping force of 4,500 N and a repeat accuracy of 0.02 mm, the low-maintenance SCHUNK TANDEM PGS3 is particularly suitable for basic applications in aluminum and plastics machining.

Special quality features are the chip-repellent design, the surface-treated components in the force flow and the long base jaw guides that prevent the chuck jaws from buckling under load. The vise can be equipped with all standard top jaws with tongue and groove (KTR, KTR-H) from the world's largest range of chuck jaws from SCHUNK. With lateral air connections and built-in keyways on the bottom, the vise is prepared for immediate installation in any machine tool.

Plug & Play: TANDEM PGS3 and VERO-S System

PGS3 and VERO-S is a perfect combination to achieve automated workpiece clamping and quicker setup changeover. The quick-change system is the perfect base for your machine table and can reduce setup times to a matter of seconds. Additionally, by having VERO-S on multiple machines, workholding such as the PGS3 can quickly be moved to different processes across your entire production facility, enabling you to get the most out of the investment.

Related Glossary Terms

  • centers


    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • chuck


    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
