Hi All,
I'm starting a new project, I want to build my own CNC Tube bender.
The idea is to build the machine fully controlled by servomotor and everything controlled with Arduino.
I would like to be able to bend steel tube with an OD up to 2.5" with wall thickness of 3-4mm.
For the first version I will use the dies of my manual bender.
For the bending part I will need a servomotor with pretty high torque and it will be direct drive.
This is where I need help,
I have no clue about what would be the required torque?
and what brand/models exist on the market and what is good or not?
I found some brands like Yaskawa on google that seems to have a pretty high torque but once again, I have no clue if it's enough or not and what alternative could also work?
I also have no idea about the price range of a such servomotor so any indications would be appreciable.
Thank you very much.
