Carr Lane ID Clamps

Carr Lane ID Clamps

ID 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 with a hex wrench pushes the clamping segments outward, and slightly downward, to exert force on the workpiece's internal bore.

These 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 allow close mounting for multi-part machining on vertical and horizontal machining centers.

• Available in seven sizes to hold any inside diameter from .26 to 2.06"

For maximum location accuracy, machine a recessin the fixture base to fit exactly with the clamps close-tolerance flange diameter. Flat-head mounting screws are furnished.

Note: ID Clamps provide mostly radial clamping force; therefore the workpiece must be firmly supported underneath - by resting directly on the clamp's moutning flange, the fixture base or fixed rest pads.

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.
