Core Application Scenarios

• Large-Scale Heavy Component Processing: With a maximum swing diameter of 630mm and an optional spindle bore of 130mm, the CW6163D excels at turning heavy shafts (max. diameter Φ630mm), large-diameter flanges, thick-walled sleeves (wall thickness ≥80mm), and large discs—core components for construction machinery (excavator boom shafts), power generation turbines (hydraulic generator rotors), and mining equipment (crusher rollers). It can efficiently process high-strength materials like HRC35 alloy steel and wear-resistant cast iron, with dimensional tolerance up to ±0.02mm, fully meeting the processing requirements of heavy-duty core parts.
• High-Precision Thread Machining for Heavy Parts: Equipped with a high-precision ground lead screw and a multi-stage hardened gear transmission system, the lathe can accurately process metric, inch, trapezoidal, buttress, and triangular threads with large pitches (up to 30mm). It is ideal for manufacturing large bolts, nuts, and threaded sleeves for heavy connectors in bridge structures, port machinery, and oil drilling equipment, ensuring tight thread fit, strong load-bearing capacity, and no loosening during long-term heavy-load operation.
• Medium to Large Batch Production of Heavy Parts: The 15kW high-power main motor provides strong and stable cutting torque, and the 6-way hydraulic tool post realizes fast tool change (≤3 seconds), reducing auxiliary processing time by 60% compared to manual tool posts. The reinforced bed structure, 经过 multiple stress-relief treatments, supports long-term continuous operation under heavy loads (max. workpiece weight 2000kg), making it suitable for medium to large batch production of standardized heavy parts such as large bearing sleeves and connecting shafts.
• Maintenance and Overhaul of Large Equipment: In industries such as metallurgy, steel, and port machinery, the CW6163D plays an irreplaceable role in maintenance work. It can repair worn parts like large rollers, heavy gear shafts, and hydraulic cylinders, and fabricate high-precision replacement parts according to samples or drawings. Its strong adaptability allows for on-site or workshop-based maintenance, minimizing downtime of key production equipment and reducing economic losses for enterprises.

Batch Advantages of Equipment

• Professional Heavy-Duty Quality, Reliable Performance: LZMT has focused on heavy-duty machine tool manufacturing for decades, and the CW6163D is a market-verified mature model. It has undergone strict high-load and long-term operation tests, with an annual failure rate of ≤0.3%, far lower than the industry average. Key components such as the spindle box and feed box are made of high-strength cast iron, ensuring durable performance.
• Ultra-Heavy-Duty Structure, Superior Rigidity: The lathe adopts an integral reinforced cast iron bed, which undergoes three times of stress relief treatment (natural aging + artificial aging + vibration aging) to completely eliminate internal stress and avoid deformation. The widened guideways (width 400mm) and reinforced spindle box structure enhance the overall rigidity and vibration damping performance. Even during heavy cutting (cutting depth up to 20mm, cutting speed up to 90m/min), the lathe remains stable without obvious vibration, ensuring consistent processing accuracy.
• Efficient Cutting and Low Operational Cost: The 15kW main motor and high-torque spindle (≥3200N·m) enable efficient processing of thick materials and high-hardness workpieces, reducing cutting time by 30%-50% compared to ordinary heavy-duty lathes. The automatic forced lubrication system delivers lubricating oil to key components at fixed time and quantity, reducing wear and extending the service life of the lathe by 40%. The modular design of key components simplifies maintenance procedures, and spare parts are widely available in the market, lowering maintenance costs.
• Cost-Effective Heavy-Duty Solution: As a used lathe, the LZMT CW6163D offers exceptional cost performance. It provides the processing capabilities of a new ultra-heavy-duty lathe at only 30%-50% of the cost. For small and medium-sized enterprises looking to expand heavy-duty machining capabilities without large capital investment, it is an ideal choice that delivers immediate production value.
