Heavy-duty CNC pipe threading lathe machine engineered for high-precision internal and external threading of oilfield pipes, drill rods, couplings, and casings. Features high structural rigidity, stepless or multi-step variable frequency spindle drives, large spindle bore capacities up to 640mm, and versatile 4-jaw manual/electric chuck clamping for high-productivity pipe processing.
Model Variants
QK Series (QK1327 / QK1332 / QK1338 / QK1343 / QK1350 / QK1363)
High-Strength Integrated Cast Iron Bed :
High-quality, high-strength cast iron integrated bed with guideway widths up to 1100mm ensures superior structural rigidity and vibration absorption during heavy pipe threading operations.
Large Spindle Bore & Versatile Chuck Options :
Comprehensive spindle bore options from 280mm up to 640mm, equipped with front and rear 4-jaw manual or electric chucks for stable, secure clamping of heavy oilfield tubular goods.
High-Torque Main Spindle Drive :
Powered by 22 kW to 37 kW heavy-duty main motors with 3-step or 4-step variable frequency speed regulation, delivering massive low-speed torque for API thread turning.
Precision Servo Motion & 4-Position NC Turret :
Equipped with 4-position NC tool turret (tool shank size up to 50x50mm) and high rapid traverse (4000 mm/min X-axis, 6000 mm/min Z-axis) for rapid and repeatable thread cutting.
Customizable Bed Lengths for Oil Country Work :
Machine bed length can be customized according to real work requirements. Extra-long bed heavy-duty lathes can be configured into simplified CNC pipe threading lathes without protective covers.
Detailed performance metrics, capacity dimensions, and drive parameters across models.
