Core Application Scenarios

• Medium to Large-Sized Mechanical Parts Processing: With a maximum swing diameter of 500mm and an optional spindle bore of 105mm, the CA6250 excels at turning external cylindrical surfaces, end faces, steps, grooves, and internal holes of workpieces such as heavy shafts, large-diameter flanges, thick-walled sleeves, and large discs. These parts are core components in construction machinery, agricultural machinery, and industrial equipment. The lathe can efficiently process high-strength materials like alloy steel and cast iron, meeting the processing needs of heavy-duty parts.
• High-Precision Thread Machining: Equipped with a high-precision ground lead screw and a complete gear transmission system, the CA6250 can accurately process metric, inch, trapezoidal, and triangular threads with a wide range of pitches. It is suitable for manufacturing large bolts, nuts, and threaded sleeves used in mechanical assemblies, ensuring tight thread fit and reliable connection performance.
• Small to Medium Batch Production: The 11kW high-power main motor provides sufficient cutting torque, enabling the lathe to handle heavy cutting tasks efficiently. The 6-way tool post allows for quick tool changes, reducing auxiliary processing time and improving production efficiency. It is suitable for both single-piece trial production and small to medium batch processing, meeting the flexible production needs of enterprises.
• Maintenance and Repair of Heavy Equipment: As a versatile heavy-duty lathe, the CA6250 plays a crucial role in maintenance workshops. It can repair worn parts such as large shafts, rollers, and gear sleeves, and fabricate custom replacement components. Its strong load-bearing capacity and flexible processing capabilities ensure the smooth operation of production equipment, minimizing downtime and economic losses for enterprises.

Batch Advantages of Equipment

• Century-Brand Quality Assurance: Shenyang Machine Tool has rich experience in manufacturing heavy-duty lathes, and the CA6250 is a mature model verified by long-term market practice. It features a reasonable structure, reliable performance, and a low failure rate, making it a trusted choice for customers at home and abroad. The global availability of spare parts further enhances its usability.
• Heavy-Duty Structure with Strong Rigidity: The lathe adopts an integral cast iron bed, which undergoes multiple stress-relief treatments to eliminate internal stress and prevent deformation. The widened and thickened guideways provide excellent rigidity and vibration damping performance, ensuring stable operation during heavy cutting and consistent machining accuracy (dimensional tolerance ±0.02mm).
• Stable Precision and Durability: High-precision spindle bearings and a ground lead screw ensure the lathe’s machining precision and surface finish. Key components such as the spindle box and feed box are made of high-quality materials and undergo strict quality inspection, ensuring long service life and stable performance.
• Easy Operation and Maintenance: The manual control system is intuitive and easy to operate, with clearly marked handwheels and dials for precise adjustment of spindle speed and feed rate. The simple structure and widely available spare parts reduce maintenance difficulty and costs, lowering the threshold for enterprise use.
• Cost-Effective Heavy-Duty Solution: As a used lathe, the Shenyang CA6250 offers excellent cost performance. It provides the processing capabilities of a heavy-duty lathe at a fraction of the cost of a new one, enabling small and medium-sized enterprises to expand their heavy-duty machining capabilities without significant capital investment.
