The CW61125B Large-Diameter Conventional Lathe is a heavy-duty horizontal turning lathe engineered for processing massive, high-load industrial shafting and components. Built with a 1,250 mm swing over bed and a 10-ton workpiece capacity, it provides reliable stability for external turning, deep boring, facing, and complex thread cutting.
Key Selection Points
1,250 mm Swing Over Bed: Clears large-diameter rotating parts during machining operations.
865 mm Swing Over Carriage: Defines the maximum effective diameter available across the apron area.
10-Ton Load Capacity: Safely supports heavy workpieces up to 10,000 kg under rated loading conditions.
Extended Bed Configurations: Accommodates part lengths from 3,000 mm to 12,000 mm (turning length 2,800–11,800 mm).
130 mm Through-Spindle Bore: Allows full passage of large bar stock and tubular workpieces.

Machining Capabilities
External Turning: Processes large cylindrical parts and heavy forged shafts with high rigidity.
Internal Machining: Utilizes the 130 mm spindle bore for deep boring and tube end processing.
Facing and Boring: Performs precise end-face squaring and internal bore enlargement on heavy castings.
Thread Cutting: Supports metric, inch, module, and diametral-pitch thread standards without complex gear changes.
Workpiece Fit
Large Shafts: Verify carriage clearance diameter, part length, and center support before setup.
Rollers & Cylinders: Match long-bed options to handle continuous cylindrical machining tasks.
Flanges & Rings: Use the 1,250 mm bed swing as the primary clearance checkpoint.
Heavy Components: Evaluate chucking, tailstock support, and loading methods together with total part weight.
How to Select the Right Configuration
Confirm Dimensions: Determine maximum diameter, actual turning diameter, and overall part length.
Calculate Turning Travel: Allow necessary travel clearances for chuck jaws, steady rests, and tool slides.
Evaluate Load Conditions: Verify the exact workpiece weight and loading procedure prior to operation.
Check Spindle Passage: Ensure bar stock outer diameter is within the 130 mm spindle bore capacity.
Applications of CW61125B Large-Diameter Conventional Lathe
Heavy Engineering: Manufacturing drive shafts, sleeves, and large mechanical rollers.
Energy Equipment: Turning generator rotors, turbine components, and heavy flange connections.
Shipbuilding & Repair: Machining propulsion shafting, rudder stocks, and marine hardware.
Maintenance Job Shops: Re-turning worn shafts and cutting custom industrial threads.
Configuration & Order Review
Specify the following parameters before requesting a proposal:
Maximum workpiece diameter, machining diameter over carriage, length, and weight
Required spindle bore, threading standards, tooling layout, and electrical voltage requirements
Production & Quality Checks
Dimensional Inspection: Key functional dimensions and slide travel are verified against technical standards.
Running Test: Spindle speed changes, feed engagement, and full system operations undergo testing before dispatch.
Documentation: Order packages include full machine parameters, inspection protocols, and operation manuals.
Buyer Evaluation Checklist
Capacity: Check swing clearances, bed length, and total weight rating against maximum part size.
Performance: Confirm spindle speeds, feed rates, cutting forces, and thread pitch ranges.
Accessories: Review steady rests, chuck options, tailstock specs, and tool posts.
Site Preparation: Confirm machine footprint, electrical requirements, and unloading crane capacity.
