Large-Diameter Machining Capacity
1,400 mm Swing Over Bed: Accommodates large-diameter cylindrical forgings, cast steel shells, and wide industrial rings without structural obstruction.
1,015 mm Carriage Clearance: Provides ample tool post clearance, allowing uninterrupted longitudinal turning across wide component surfaces.
Scalable Bed Lengths: Adaptable bed options support maximum turning lengths up to 11,800 mm, making it ideal for processing extra-long industrial shafts.
Spindle and Cutting Range
130 mm Through-Bore Spindle: Allows long bar stock and pipe materials to pass through the headstock, streamlining setup times for continuous production.
22 kW Heavy Drive Motor: Generates high low-end torque across speeds from 3.15 to 315 r/min, enabling aggressive material removal on hard alloys.
Threading Capability
Versatile Multi-Pitch Processing: Cuts 44 metric (1–120 mm), 31 inch (28–1/4 TPI), 45 module (0.5–60 mm), and 38 diametral (1/2–56 DP) threads without changing complex gear combinations.
Feed and Tooling
Precision Feed Control: Features longitudinal feeds from 0.1 to 12 mm/rev and cross feeds from 0.05 to 6 mm/rev, paired with a 3,740 mm/min rapid traverse.
Rigid Swivel Tool Post: Features a ±90° swiveling post with 580 mm cross-slide travel, holding heavy-duty 45 mm tool shanks securely under deep cutting loads.
Tailstock Configuration
Heavy-Duty Rear Support: Built with a massive 160 mm diameter quill, 300 mm manual travel, and a Morse 6 taper to hold extended workpieces rigidly during high-load turning operations.
Typical Applications of CW61140B Large-Diameter Conventional Lathe
Heavy Shaft Turning: Machining marine drive shafts, generator rotors, turbine shafts, and steel mill rollers.
Large Cylindrical Components: Turning thick-walled pressure pipes, large hydraulic cylinders, industrial flanges, and sleeve bearings.
Deep Boring & Threading: Internal boring, counterboring, and pipe threading on heavy valve bodies and mining equipment fittings.
Material Compatibility
Broad Metallurgy Range: Optimized for rough and finish machining on carbon steel, alloy steel, cast iron, bronze alloys, and tough non-ferrous metals.
Standard Configuration
Factory Included Equipment: Comes standard with a Φ1,000 mm four-jaw chuck, Morse 6 dead center, flood cooling system, halogen work lighting, and foundation anchor bolts. Models 2 meters and longer include heavy-duty steady and follow rests.
How to Select the Right Configuration
Verify Machining Swing: Compare maximum outer component diameter against the 1,400 mm bed swing and 1,015 mm carriage clearance.
Determine Bed Length: Select the appropriate bed distance (1,500 mm to 12,000 mm) based on overall part length and required turning travel.
Confirm Spindle & Weight Limits: Ensure bar stock fits within the 130 mm spindle hole and total load remains under the 6,000 kg capacity limit.
