Overview
The QK1327 CNC pipe threading lathe redefines heavy-duty pipe machining with its 280mm spindle bore and dual chuck system. Engineered for 130-270mm diameter pipes and 6-ton payloads, this 22kW powerhouse delivers ±0.01mm threading accuracy at 10-320 RPM speeds-crushing API 5CT standards for oil drill pipes. With hardened guideways (HRC50) and 4000mm/min rapid feeds, it tackles 3000mm-long casing in one chucking, proving that industrial durability needs no compromise on precision.
Core Applications
Oilfield Drill Pipe Threading
Cut API 5CT L80 threads at 25mm/min feed rates. The dual manual chucks (φ800mm) eliminate pipe whip during deep threading, while MT6 tailstock taper ensures concentricity under 12kN thrust-proven 50% faster than single-chuck lathes in Texas shale fields.
Nuclear Coolant Pipe Refurbishment
Machine Inconel 625 seal faces with Ra 1.6μm finishes. Four-position turret + KND1000Ti system enable compound angle threading (NPT, BSPT) without re-clamping-Japanese nuclear plants report 92% first-pass yield.
Mining Conveyor Sleeve Machining
Turn 270mm-diameter manganese steel sleeves (HB400) in one setup. 755mm-wide bed absorbs interrupted cuts, achieving 0.4mm Ra without chatter-Chilean copper mines cut cycle time by 45%.
Engineering Superiority
Rigidity Redefined: Monolithic HT250 casting (10.5T weight) with dovetail slides withstands 8kN vibrations. Super audio-quenched guideways extend service life to 20,000+ hours.
Zero-Downtime Threading: Quick-change gearbox cuts metric/imperial/modular threads without gear swaps. Automatic peck cycling prevents 90% tap breakage.
Smart Ergonomics: Centralized lubrication + slideway plastic coating reduce friction by 40%-critical for desert sand environments.

Pro Tip
Apply EP2 lithium grease weekly to bedways-reduces wear by 80% in sandy climates. Always engage low-speed torque mode when threading hardened alloys to prevent chattering.
