Photo on the left shows the mandrel that is inserted into the pipe prior to bending. The "donuts" flex and conform to the shape of the pipe as it is bent keeping it from wrinkling or collapsing. White grease is injected through the mandrel into the interior of the pipe. As the bend is completed, the machine automatically withdraws the mandrel.

The photo on the right shows a completed bend wrapped around the die. Note the serrations on the clamps. Once the machine has been set up for a given pipe diameter, the operator enters the desired bend angle into the digital control panel and the bending process is fully automatic.





100_0407 100_0418 Simple bends are cut from the tubing once completed. More complex bends are secured in the 3-Jaw chuck shown at left. When one bend is completed, the chuck is rotated to the correct angle and the tube is advanced the correct distance for the next bend. The mandrel is attached to the rod shown in the center of the chuck and can be seen continuing to the rear of the machine in the upper right of the picture.

Mandrels are shown in the photo at right. Each diameter of tubing requires a seperate mandrel. Bronze mandrels are used for stainless steel and chrome mandrels for mild steel. Some mandrels have as many as five "donuts".
