Germ tube from charging conduit is pushed over the mandrel. The auto
expanding mandrel fixes the tube firmly, and starts spinning at high speed. At
the first stage, tube end is cut by the cutting knife to the required length.
The next stage, tube nozzle is cut well and finished to form thread by thread
rolls to required specifications. At third station, the motor driven brush
polishes the head and shoulder of the tube.
The last working station is for unloading materials. The unloading board controlled by cam pushes the processed tube out from the mandrel. Following the flat belt, the tube comes to the charging conduit which can connect with conveyor chain of annealing oven.
A. Tube diameter range: φ16mm-φ40mm
B. Tube length range: 200mm
C. Production speed: ≤120tubes/min
D. Motor power: 8.35KW
E. Dimensions: 2800*2500*1900mm

A. Ferguson indexer increases indexing accuracy. The machine has high abrasion resistance and low working noise.
B. The waste removal device automatically collects aluminum scraps into the waste drum.
C. SIEMENS PLC controls speed and frequency and displays information like production speed on its text panel.
D. Frequency converter is used to control the speed and it is convenient to replace mandrel of different types. Mandrel board and mandrel are processed by CNC equipment, which increases the stability of the machine.
