Titanium nitriding, a chemical coating applied to carbon and tool steel cutting and forming tools to reduce friction and increase hardness, thereby extending tool life. TiN (pronounced “tin”) coating, a relatively expensive process, has limited utility for tube-bending tools primarily because improvements in tool set-up (along the lines of the four-step forward-mandrel, low-pressure procedure) have a greater impact in extending tool life at no additional cost.

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.
