    Vacuum Workholding Plates

    Also known as vacuum chucks, these plates secure thin and flexible parts that can’t be held with vises or clamps for milling, drilling, routing, and finishing operations. Connect the system to your shop’s compressed air supply and it's ready to use. For applications requiring only part of the plate surface, use the gasket cord to seal off the area.

    Riser

    Riser with 1" Wide Step

    Riser with 2" Wide Step

    Risers, also known as vacuum pods, raise the workpiece off the vacuum table to give the cutting tool better access. Suction transfers from the table through the top of the riser, so to get a firm hold the workpiece must make contact with the full top length and width of the riser.

    Retracting Stop Pins with Pin

    Retracted

    Retracting stop pins let you repeatably locate parts on your vacuum table. After positioning your workpiece against these pins, turn on the vacuum and the stop pins retract, dropping out of the way so the cutting tool has full access to the workpiece.

    Air-Powered Machine Vises

    Compressed air controlled by a foot pedal allows hands-free operation. Step on the pedal to instantly close the moving jaw; step again to release it. Use these vises in production applications with frequent insertion and removal of workpieces on Bridgeport-style milling machines and drill presses. Vises with a jaw height of 1 1/4", 1 5/16", and 2 1/2" can also be used on surface grinders.
    To calculate the gripping force on your workpiece, multiply your inlet air pressure by the gripping force factor. Add an air regulator to control force.

    Fixed Base—Single Acting

    Fixed Base—Double Acting

    Single Acting—Single-acting vises require the jaw to be manually set to the desired position before use, so these vises are best for repetitive clamping of consistent workpiece sizes. Once the jaw is set, activating the air pressure will move the jaw up to 5/8" to clamp. When air pressure is released, a spring return inside the air cylinder returns the jaw to the set position.
    Double Acting—Double-acting vises use air pressure to open and close the jaws without manual adjustment, making these vises a good choice when clamping workpieces of varying size.
