The heat exchanger extruded fin tube machine is specially designed for producing single-metal or double-metal finned tubes in different diameters.
Main features of heat echanger extruded fin tube machine:
-- Tool holder and tool holder body adopt the advanced dual-circular key structure to withstand torque, displacement of accurate and reliable.
-- Tool holder adopt split type design, it is very easy to blade debugging, washable and install of the blade.
-- Spindle bearing can be moved using conical hydrodynamic sliding bearings, bearing to maximize the utilization.
-- Universal joints and shaft key link between all lines of Hot Pepper. Cooling box separate from rolling mill machine.
-- Closely with technical data, rolling fin efficient, durable blades.
