The C61125 Large-Bore Heavy-Duty Conventional Lathe is built for stable metal turning on large-diameter, long, and heavy rotational parts. Engineered with a 1,250 mm swing over bed, 900 mm swing over carriage, and a 16-ton loading capacity, this machine delivers high-rigidity cutting across demanding workshop environments. Available bed configurations support workpiece lengths up to 12,000 mm, making it a reliable solution for heavy machinery, marine engineering, and energy equipment manufacturing.
Key Features of C61125 Large-Bore Heavy-Duty Conventional Lathe
1,250 mm Swing Over Bed: Accommodates oversized forged shafts, thick rings, and large steel castings with complete clearance.
16-Ton Load Capacity: Heavy-duty casting bed with wide guideways absorbs severe cutting vibrations during heavy-roughing passes.
100 mm Through-Spindle Bore: Allows long bar stock and pipe materials to pass directly through the spindle nose for quick setup.
Universal Threading Gearbox: Enables direct cutting of metric, inch, module, and diametral threads without frequent manual gear swapping.

Machining Applications
Heavy Shaft Production
Turns long marine propeller shafts, generator rotors, and heavy industrial drive axles with high concentricity and surface finish quality.
Large Industrial Components
Efficiently machines large-diameter steel pipe flanges, heavy valve bodies, thick-walled cylindrical sleeves, and rolling mill drums.
Maintenance & Equipment Repair
Re-bores worn industrial housings, recuts damaged threads on drill pipes, and restores worn heavy machinery components back to operational specs.
Workpiece Selection Guide
Clearance Verification: Measure your part's maximum outer diameter against the 1,250 mm bed swing and 900 mm carriage swing to guarantee smooth rotation.
Bed Length Choice: Base your machine bed selection on the maximum required turning length (up to 11,800 mm) rather than overall part length.
Weight & Center Balance: Ensure workshop overhead cranes meet the 16-ton limit and confirm workpiece center-of-gravity balance before mounting between centers.
