How to choose this product

expandable-chuck

Expanding mandrels are tool components used to grip objects by their inner diameter. They hold workpieces for machining applications such as turning, milling and grinding.

Applications

Expanding mandrels are most often used on lathes for turning operations. They can also hold parts for measuring purposes, such as checking for concentricity. They also can hold multiple parts simultaneously, making them preferable to lathe chucks for certain turning operations.

Technologies

The expanding mandrel holds a hollow workpiece from within to facilitate work on its exterior surface. A screw or piston gradually expands the tapered mandrel until it grips the piece firmly.

How to choose

Be sure to determine the approximate diameter of the workpiece when selecting an expanding mandrel.

Advantages
