Product features

  • WG-38/51/76 CNC steel tube bending machine is mainly used for bending different kinds of tube materials,for example round or square mild carbon steel tube,201 or 304 stainless steel tube,rectangular steel tube,alumimum tube,cooper tube or other special shaped steel tube etc. And this machine always bend tubes into different angles from 5 to 180 degrees.
  • This model is our latest technical achievements of the research and development.Having the following characteristics:
  • 1.Use Micro CNC computer panel control the bending angles and batches.
  • 2.Gear drive is durable and maintenance is convenient,only add the grease oil into the gear box.
  • 3.Thin tube and thick tube could work well by this machine.
  • 4.Foot switch add CNC operation,let the tube processing so easy and convenient.

  • Every connection is proof-tested by a non-destructive tensile test during the extrusion cycle.
  • Standard parallel threads: no torque wrenching required and no risk of cross-threading.
  • Visual inspection of joints is sufficient.
  • Excellent fatigue performance thanks to rolled threads.
  • Compliant with OSHA regulations.

Having installed millions of connectors to date on some of the most technically demanding projects in China, Grace has proven itself to be the reliable, scalable and top performing Chinese rebar connector.
