Extruded: The machine is designed for low tube finning operations with a fast and easy set-up and changeover. Typical set-up/changeover time is 10-15 minutes. The machine has three rolling heads. Material can be: copper and copper alloys, aluminium of all alloys, steel (common and stainless). Machine operation and part programming are done at the machine CNC/PLC control panel. Programming is user friendly and very easy to learn, with minimal time required to create complete programs for finning operatoins. 1) Maximum pressure applied: 300 kN 2) Maximum fin diameter: 60 mm. 3) Maximum through feed length: Unlimited meters 4) Maximum head inclination: 6 deg. 5) Main motor power: 100 hp 6) Fin per inch: 6 - 26 fpi 7) Tube diameter: 10 - 80 mm. 8) Productivity: 3-7 m/min.
