Description of Extruded Fin Tube Machine
An extruded fin tube machine is also called a tube finning machine, extruded high fin tube machine and extruded low fin tube machine.

1.Tool holder and its body adopt the advanced dual-circular key structure to withstand torque and achieve accurate and reliable displacement.
2.Tool holder adopts split type design, making blade installation, debugging and cleaning operations easier.
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 is separated from rolling mill machine.
5.Closely with technical data, rolling fin efficiently, durable blades.
