► RÖHM | Segment Clamping Mandrels

Internal Workholding for Precision CNC Machining

Complex machining often requires gripping a component from the inside rather than the outside. Röhm | Segment Clamping Mandrels are designed for this purpose, providing internal clamping that holds cylindrical parts securely during turning, grinding & finishing operations. These mandrels expand inside the bore of a component which allows machinists to machine external surfaces with excellent concentric accuracy.

Inside high precision machining environments internal clamping systems are essential when working with parts such as rings, sleeves, gears & bearing housings. Segment mandrels expand evenly across the internal diameter which keeps the workpiece stable while cutting tools operate under load. Stable clamping reduces runout while protecting surface finishes across demanding machining operations.

Machinists preparing components for internal clamping often work at fabrication benches fitted with Bench Vice, Workbenches & Welding Clamps & Magnets where parts are inspected before entering machining cycles. Once machining work is complete technicians frequently move components to finishing stations using Metal Cutting & Grinding Tools, Angle Grinders & Grinding & Cut-Off Wheels for secondary finishing tasks.

Precision manufactured with hardened steel bodies & segmented clamping elements Röhm | Segment Clamping Mandrels deliver dependable internal workholding performance across demanding workshop environments.
