Internal gripping or expanding mandrels are available in a wide variety of shapes and sizes.
Internally gripping mandrels are used to support a part that requires machining on the outside, while being gripped internally. We make a variety of shapes and sizes for a wide selection of industry sectors.
The workpiece is held true to an internal bore and rotated with the mandrel allowing for machining on the outside. We are able to produce either to your design or to fit your requirements.
