    ID Clamps

    ID Clamps

    Clamps & Accessories

    ID expansion clamps expand to self-center and clamp on the inside diameter of a workpiece, leaving the outside clear for machining. Tightening the tapered center screw of ID clamps with a hex wrench pushes the clamping segments outward, and slightly downward, to exert a force on the workpiece's internal bore. ID expansion Clamps allow close mounting for multi-part machining on vertical and horizontal machining centers.
    These ID expansion clamps are designed to have their outside diameter finish machined by the customer to suit the bore size because maximum diameter expansion is limited (.005 to .025", depending on the size). ID clamps are available in seven sizes to hold any inside diameter from .26" to 2.06". Carr Lane ID expansion clamps are proudly made in the USA.

    Application Information

    Each of these six workpieces is clamped by two ID Clamps – a large clamp in the large bore and a small clamp in the slot. The large clamp is also the primary locator, so would be tightened first. The small clamp is also the secondary (radial or “clocking”) locator, so would be tightened second. By using ID Clamps, the workpiece’s entire outer surface is accessible for machining.

    Installation

    For maximum locational accuracy, machine a recess in the fixture base to fit exactly with the clamp's close-tolerance flange diameter. Flat-head mounting screws are furnished. Please note, ID Clamps provide mostly radial clamping force; therefore the workpiece must be firmly supported underneath – by resting directly on the clamp's mounting flange, the fixture base, or fixed rest pads.

    Machining

    Before finish machining the clamp's outside diameter on a lathe or milling machine, expand the clamp slightly (.002 - .003") from its relaxed diameter by tightening the tapered center screw. Secure with a jam nut if necessary. Reduce the outside diameter only as much as required for smooth workpiece loading, always staying within the expansion range for that clamp size.

    Material

    Body > 12L14 steel, black oxide finish. Center screw > Alloy steel. Mounting screws > Alloy steel, black oxide finish. DFARS and RoHS compliant.
