Selecting the right mandrel and wiperTube bender operators could rely on complex mathematical formulas and rules of thumb, but it’s much quicker to use a tooling chart. This sort of chart lists the two main bending criteria, D of bend and wall factor, on the X and Y axis, respectively. However, these charts have just two axes, and...

The right stuffThe best material for a tube bending tool is the most cost-effective in terms of the ratio of tool life to tool cost. A cost-effective tool tends to wear out rather than break at the end of its service life. This article addresses choosing the optimal material for a rotary die tube bending...

Setup or cover-up?Setting up the tooling for a tube or pipe bending machine isn't as simple as it seems. Many variables are involved, making this a difficult task. A further complication is the tendency for many operators to adjust various pressure settings to compensate for poor tooling setup. The bend might turn...

The wiper die's feathered edgeThe mechanical aspects of rotary draw tube bending haven't changed since modern tooling was developed 50 years ago. Likewise, the role of the tooling (mandrel, pressure die, bend die, and wiper die) hasn't changed. However, tube fabricators these days have many choices in regard to the tooling,...
