STC series CNC pipe threading lathes with Fanuc system can do cylinder and tapered threading of metric and inch standards. Also it can do more conventional machining such as arc-cone facing, regular threads, inside and outside surfaces of cylinder-shaped parts, and also disc-shaped parts. It is especially suitable for casing pipe in the petroleum industries. The machining accuracy can be up to grade IT7 and the surface finishing accuracy can reach Ra1.6μm.

 

Feature:

  • The front and rear chucks with big span
  • Integral casting bed
  • Big section and span hardened-steel guideway with high loading capacity and good hard-wearing resistance
  • Big spindle bore Ф120/Ф205/Ф245/Ф260/Ф355
  • With finite hydraulic device
  • Vertical 4-position electric turret
  • Walking beam transfer can be furnished, high automation, shorten the time of charging and blanking convenience and safety, realized the serialized manufacture automatically
