Heavy-Duty Capacity for Large Industrial Turnings & Pipe Processing
The Qingluan CK6160 Large-Bore Flat Bed CNC Lathe is built for extreme rigidity when turning oversized workpieces. With a massive 600 mm swing capacity, extra-wide 450 mm hardened bedways, and large spindle bore options up to Φ105 / Φ130 mm, the CK6160 is the ultimate machine tool for heavy industrial equipment manufacturers, mining machinery rebuilders, energy valve producers, and oilfield pipe threading shops.
Core Technical Advantages
- Extra-Wide 450 mm Box-Way Foundation: Cast from premium alloyed gray iron with double-wall ribbing, the 450 mm guide rail span eliminates saddle tilting and provides rock-solid foundation for deep-cut facing and peeling operations on heavy steel forgings.
- Large-Through-Bore Spindle Options: Designed for oilfield API pipe threading, hydraulic cylinder rod turning, and hollow shaft machining, with front and rear dual-chuck mounting provisions.
- Robust Heavy-Duty Tool Carrier: Heavy vertical electric tool post accepts up to 32 × 32 mm solid carbide toolholders, guaranteeing zero deflection under heavy depths of cut (up to 8 mm single-pass depth in structural steel).
