CK61140X3000 Heavy Duty Flat Bed CNC Lathe | Large Precision Turning Machine

The CK61140X3000 is a large-sized horizontal flat bed CNC lathe customized with 3000mm distance between centers, specially developed for heavy-load continuous turning of extra-long shaft, sleeve and cylindrical parts. Equipped with ultra-rigid integral cast iron bed and high-power main spindle system, this model balances heavy cutting capacity and long-term dimensional stability, widely adopted in heavy machinery, new energy, metallurgy and marine equipment manufacturing sectors.

The machine body adopts one-piece high-strength cast iron casting with aging stress relief treatment, effectively eliminating internal casting stress. The widened rectangular guide rail improves anti-vibration performance drastically during deep rough cutting and high-feed machining, avoiding tool chatter and workpiece surface roughness degradation, ideal for long-bar heavy cutting scenarios of CK61140X3000 3-meter lathe.

Hydraulic tailstock sleeve travel reaches 120mm with MT8 internal taper, capable of bearing ultra-heavy workpiece weight up to 6000kg between centers. It provides reliable axial support for overlength shafts, preventing bending deformation during high-speed turning.

The CK61140X3000 large CNC lathe supports mainstream global CNC controllers for flexible configuration according to customer workshop automation demands:

GSK 980TDi: Cost-effective domestic system, easy programming and maintenance, popular for small & medium batch production

FANUC 0i-TF: Stable international brand system, strong anti-interference, suitable for continuous 24h unmanned production line

Siemens 828D: Intelligent full-function system, supports complex curve turning and digital workshop data interconnection

All control systems support turning outer circle, inner hole, taper, arc, end face, grooving, chamfering and metric/inch thread cutting, realizing one-clamping full-process forming of long shaft parts.
