Tube processing systems for bending and notching a tube fed from a feed position. The tube processing system includes a notching system and a bending system. The notching system is configured to cut a notch in the tube. The bending system is disposed between the notching system and the feed position and is configured to bend the tube. The notching system includes a cutting head and a positioning system. The cutting head is configured to cut a notch in the tube. The positioning system movably supports the cutting head and is configured to move the cutting head relative to the tube to a selected cutting position. The bending system includes a bending die and a clamp. The bending die is rotationally driven to bend the tube. The clamp is configured to secure the tube to the bending die.
