Comprehensive Machining Capabilities

  • Precision Pipe Threading Cycles: Specialized CNC macro routines for single-point chasing of API taper, metric, inch, and buttress pipe threads on pipes from Φ30 mm to Φ126 mm.
  • Big-Bore 130 mm Spindle: High-rigidity spindle design handles long drill rods and tubes passing straight through the headstock with optional dual front/rear chucking.
  • General CNC Turning Versatility: In addition to threading, performs standard external turning, boring, facing, and contouring of shafts and heavy disc workpieces.

Key Engineering Highlights

  • 550 mm Extra-Wide Flat Bed: High-strength casting with wide induction-hardened ways supports up to 3-ton workpiece loads without vibration.
  • Robust MT6 Tailstock: Φ100 mm quill diameter with 250 mm stroke provides rock-solid centering stability on heavy drill pipes and long shafts.
  • High-Torque 11 kW Drive: 3-step frequency conversion gearbox produces formidable cutting force during deep thread-cutting passes in tough alloy steels.
