What is a collet mandrel?

Mandrels and collet chucks are used for clamping most rotationally-symmetric workpieces for cutting or grinding machining on machine tools or machining centers. Furthermore, they are used on measuring machines for high-precision clamping.

How does an expanding lathe mandrel work?

The systems works by sliding the expanding sleeve over the mandrel, locking it into place with a pin and drawing the mandrel back axially using the machine’s drawtube. This motion pulls the expanding sleeve further back onto the mandrel causing the two tapers to interface and the mandrel to expand.

In manufacturing coiled helical spring, the spring wire is wrapped around a mandrel that serves as a support; when seamless tubing is being extruded, a long mandrel forms the internal diameter. Tool-carrying shafts are usually known as arbors, but the words mandrel and arbor are frequently used interchangeably.
