The CK61160 (32/63t) Large CNC Lathe is a heavy-duty horizontal machining system engineered for turning massive shafts, discs, and industrial forgings. Available in 32-ton and 63-ton loading capacities, this precision lathe delivers high-rigidity external turning, deep boring, facing, and thread cutting across bed lengths up to 20,000 mm.

Key Features of CK61160 (32/63t) Large CNC Lathe

Dual Ton Load Structural Design
Built with 32 t and 63 t capacity options to safely support high-mass forgings without structural sag.

High-Torque Machining Capacity
Delivers up to 120 kN·m torque and 120 kN cutting force for aggressive material removal on tough alloys.

HT300 Cast Iron Bed
Features an integral three-guideway HT300 cast base subjected to secondary aging to preserve long-term accuracy.

Precision Feed & Positioning
Utilizes rack-and-pinion drive on the Z-axis and precision ball screws on the X-axis for high axial stability.

Machining Applications

Power Generation Turbines & Rotors
Designed for roughing and finishing long power shafts, generator rotors, and turbine drive components with continuous support.

Mining & Heavy Industrial Rollers
Efficiently turns high-hardness mill rollers, crusher shafts, and steel mill drums requiring heavy depth of cut.

Marine & Aerospace Cylinders
Executes precise facing, threading, and deep-hole boring on large marine propulsion shafts and pressure vessel flanges.
