Core Application Scenarios

• Large-Scale Heavy Component Processing: Boasting a maximum swing diameter of 800mm over the bed and a spindle bore of up to 130mm, the CW6280B excels at turning extra-large workpieces such as heavy-duty shafts, large-diameter flanges (up to Φ800mm), thick-walled sleeves (wall thickness ≥50mm), and large discs. It is a key equipment in the production of turbine shafts for thermal and hydropower plants, propeller shafts for ships, crankshafts for large diesel engines, and bearing seats for heavy machinery. The lathe easily processes high-hardness and high-strength materials, including high-strength alloy steel, titanium alloy, and wear-resistant cast iron.
• Thick-Walled Pipe and Special-Shaped Part Machining: The large spindle bore design allows the lathe to process thick-walled steel pipes, seamless steel tubes, and special-shaped rotating parts (such as conical surfaces, curved surfaces, and multi-step shafts) widely used in petroleum pipelines, chemical equipment, and construction machinery. The 6-way hydraulic turret enables quick tool changes (tool change time ≤3 seconds), supporting continuous processing of multiple processes (turning, grooving, chamfering, boring, and threading) in one setup, which significantly reduces workpiece clamping time and improves processing efficiency by 40% compared to ordinary lathes.
• High-Precision Thread Machining for Heavy-Duty Parts: Equipped with a high-precision lead screw (precision grade C7) and a multi-stage gear transmission system, the CW6180B can accurately machine metric, inch, trapezoidal, buttress, and triangular threads with large pitches (up to 24mm). It is ideal for manufacturing threaded components of heavy-duty connectors, such as large bolts, nuts, and threaded sleeves used in construction machinery, mining equipment, and bridge structures, ensuring tight thread fit, strong load-bearing capacity, and long-term reliability.
• Maintenance and Repair of Large Equipment: In industries like metallurgy, mining, port machinery, and steel production, the CW6280B serves as an indispensable maintenance tool for repairing worn heavy-duty parts (such as large shafts, rollers, gears, and hydraulic cylinders) and fabricating custom replacement parts. Its strong adaptability and flexible processing capabilities allow for on-site or workshop-based maintenance, minimizing downtime of key production equipment and reducing economic losses for enterprises.
• Medium to Large Batch Production of Heavy Parts: The reinforced bed structure (stress-relieved multiple times) and powerful 15kW main motor enable the lathe to operate continuously for long periods under heavy loads (max. workpiece weight 2000kg). It is suitable for medium to large batch production of standardized heavy parts, such as large bearing sleeves, flange plates, and connecting shafts. The automatic forced lubrication system ensures stable operation of key components (guideways, spindle, and lead screw), while the optional hydraulic chip conveyor keeps the working area clean and further enhances production efficiency.

Batch Advantages of Equipment

• Legendary Brand and Proven Reliability: Shenyang Machine Tool is a world-renowned enterprise with a history of over 100 years, and its heavy-duty lathes are recognized globally for their superior quality and durability. The CW6280B is a mature model that has undergone rigorous testing in harsh working environments (high load, long continuous operation), featuring a low failure rate (≤0.5% annual failure rate), strong durability, and global availability of spare parts. Choosing this lathe means partnering with a trusted brand with a proven track record in the heavy machinery industry.
• Ultra-Heavy-Duty Structure with Superior Rigidity: The lathe adopts a one-piece reinforced box-type cast iron bed, which undergoes multiple stress-relief treatments (natural aging + artificial aging) to eliminate internal stress and prevent deformation. The widened and thickened guideways (width up to 300mm) and reinforced spindle box (cast iron integral structure) provide exceptional rigidity and vibration damping performance. Even during heavy cutting (cutting depth up to 15mm, cutting speed up to 100m/min), the lathe maintains stable operation, ensuring consistent machining accuracy (dimensional tolerance ±0.02mm) and excellent surface finish (Ra ≤1.6μm).
• Powerful Cutting Performance and High Efficiency: Equipped with a 15kW high-power main motor and a high-torque spindle (max. torque ≥3000N·m), the CW6280B delivers strong cutting force, enabling efficient processing of thick materials and high-hardness workpieces (up to HRC35). The 22-speed spindle speed range (5-1000 rpm) and adjustable feed rates (0.03-4.0 mm/rev) allow for optimal parameter matching for different materials and processing requirements, reducing cutting time by 30%-50% compared to ordinary heavy-duty lathes. The hydraulic tool post with 6 stations supports quick tool changes, minimizing auxiliary processing time.
• Humanized Design and Easy Operation & Maintenance: The lathe features an ergonomic operation panel with clearly marked handwheels, levers, and digital displays (optional) for precise adjustment of spindle speed, feed rate, and tool position. The large operating space (≥1.2m wide) and adjustable operator seat reduce labor intensity for workers during long shifts. The centralized automatic forced lubrication system delivers lubricant to key components at fixed intervals, reducing wear and extending the service life of the lathe by 30%. Additionally, the modular design of key components (spindle box, feed box) simplifies maintenance and repair, lowering operational costs for enterprises.
• Cost-Effective Heavy-Duty Solution: As a used lathe, the Shenyang CW6280B offers an unbeatable cost-performance ratio. It provides the same processing capabilities and reliability as a new ultra-heavy-duty lathe at only 30%-50% of the cost. For small and medium-sized enterprises, heavy industry workshops, and maintenance bases looking to expand their heavy-duty machining capabilities without large capital investment, this lathe is an ideal choice that delivers immediate production value and enhances market competitiveness.
