Expanding Mandrels

Expanding mandrels are used to hold workpieces together internally; the expanding clamps are machinable so they can easily be modified to suit awkwardly shaped workpieces, and prevent user and item distortion. It must be noted that some expanding mandrels require a through bore to access the clamping screw, while others use a side clamping mechanism for blind bore workpieces. Expanding mandrels are frequently used for milling, gear cutting, grinding, and vertical boring. We offer three types of expanding mandrels, these include ID Xpansion clamps, manual actuators for mills and lathes, and Side-Loc-Xpansion clamps.
