Interesting project, an acquaintance used to pay occasional visits to a company that bent car exhausts.The machine had the facility to feed the tube along to the next bend location and then rotate it before adding the desired bend so that the finished article just needed an end flange added.Do you intend to build a machine with this sort of capability?

Yes it's correct I'm looking to build a real CNC as I explained in first post, so after the bend part solved, I will build an axis positioner that will push and rotate the tube to the next bend position.

I have build a bike frame with the manual bender and it has been very annoying to do the mirror part so I looked at CNC Tube bending and obviously the cost of those machine is huge so I thought why not building one as it doesn't seems to be unreachable
