One of the most common modes of bending is rotary draw bending. centerline to get acceptable bend quality. The centerline radius of the tube diameter needs to be approximately two times the diameter of the bend.
You can set it up to make a 90-degree bend and a 45-degree bend, for example. A lot of times cleaning the part consumes as much time as bending it.Īlthough furniture, lawn mower handles, and generator frames often are symmetric, a compression bender isn’t limited to symmetrical parts. Because you don’t use oil, no cleaning of the part is needed afterward. In addition to speed, some of the advantages are that no oil is used inside the part and that you don’t use a mandrel inside the tube, which is why the bend is a little out of round.
