Halder centering and clamping mandrels are workholding components used to center and clamp parts quickly and repeatably, often by clamping from the inside diameter (application dependent). Mandrel-style workholding is commonly chosen for round parts, rings, and components with a bore where you want consistent concentricity and fast changeovers. By combining centering and clamping in one element, these mandrels can help reduce setup time and support repeatable positioning in machining and inspection workflows (application dependent).

Frictional Centering and Clamping for Components with Locating Bores - Halder centering clampings (centering clamping elements and centering clamping mandrels) are mechanical clamping elements for centering and clamping components with a locating bore - through bore or blind hole. With these centering clamps, often also referred to as bore clamps or hole clamps, components can be centered and clamped frictionally. Centering clamping mandrels can be adapted to the respective mounting diameter by turning/milling for custom applications.
