► RÖHM | Mandrels & Accessories

Precision Internal Workholding for CNC Machining

A Röhm mandrel is a precision internal workholding tool designed to grip a component from the inside diameter so the external surface can be machined with high concentric accuracy. Röhm | Mandrels & Accessories are widely used across CNC machining workshops where internal clamping provides better alignment than traditional external chuck gripping.

Across manufacturing plants, engineering workshops & precision machining facilities, expansion mandrels are used to hold cylindrical components such as sleeves, bushings, rings & bearing housings. When the mandrel expands inside the bore it distributes clamping pressure evenly across the workpiece which helps reduce distortion during machining.

Before machining operations begin technicians commonly prepare parts at setup benches equipped with Bench Vice & Workbenches where components are inspected, measured & staged for machining.

Once installed in the machine the mandrel works alongside core workholding systems including Röhm | Segment Clamping Mandrels, Röhm | Jaws & Sets, Röhm | Sliding Block & Röhm | Centres & Accessories to maintain stable positioning during turning operations.

Engineered with hardened steel construction, precision expansion segments & tight tolerance machining surfaces, Röhm mandrels deliver reliable internal workholding performance for demanding industrial machining environments.
