This machine is specially for producing extruded type spiral fin tubes in different diameters.It is capable for both bimetallic
fin tubes and monometallic tubes, by changing extruding blades.
high fin tube (bimetallic) & low fin tube (monometallic) extruding blades
- Tool holder and tool holder body adopt advanced dual-circular-key structure, big torque withstanding, accurate and reliable displacement.
- Tool holder adopts split type design, which is very convenient for blade debugging, cleaning & fixing
- Blade spindle bushing adopts special taper sliding bearings which brings max. bushing utilization.
- Universal joints and spindles are of spline linking; And coolant cooling tank is separate to main rolling machine.
- Special extruding blade design, high efficient, long blade life
