Heat Exchanger Extruded Fin Tube Machine

 Description of extruded fin tube machine (tube finning machine):
Tube finning machine is also called finned tube rolling machine, extruded fin tube machine, tube finning machine, bi-metallic fin tube machine, high fin tube machine or low fin tube machine, etc., for rolling single or dual-metal finned tubes used in heat exchangers and heaters.

Main features of extruded fin tube machine (tube finning machine):
1) Tool holder and tool holder body adopt the advanced dual-circular key structure to withstand torque, displacement of accurate and reliable.
2) Tool holder adopt split type design, it is very easy to blade debugging, washable and install of the blade.
3) Spindle bearing can be moved using conical hydrodynamic sliding bearings, bearing to maximize the utilization.
4) Universal joints and shaft key link between all lines of Hot Pepper. Cooling box separate from rolling mill machine.
5) Closely with technical data, rolling fin efficient, durable blades.
