Often referred to loosely as the mandrel, which see, a complete mandrel assembly consists of: [1] a mandrel body, [2] a mandrel nose insert, [3] a mandrel link or insert link, [4] a mandrel screw, and, if necessary, [5] a ball sub-assembly. A non-inserted mandrel assembly, sometimes called an “aircraft type” or “aircraft quality” mandrel assembly, does not include the second component, the nose insert.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
