CK61180G CK61200G Heavy Duty CNC Lathe Machine

Heavy-duty CNC lathes are specialized CNC machine tools designed for machining large, extra-heavy, and complex rotating parts. Compared to conventional CNC lathes, they offer a significant improvement in size, load capacity, drive power, and overall rigidity. They can typically process diameters of several meters, lengths of more than ten or even dozens of meters, and load capacities of tens or even hundreds of tons.

Features

Heavy-duty CNC lathes are a symbol of China's heavy industrial strength. They address the challenge of producing large, basic components with precision and accuracy. They offer more than just a simple increase in size; they represent a comprehensive upgrade in rigidity, power, stability, and control technology. They are the cornerstone equipment supporting the development of the large-scale equipment manufacturing industry.

In addition to inheriting the high precision and efficiency of conventional CNC lathes, heavy-duty CNC lathes, due to their "heavy-duty" design, offer the following outstanding features:

1. Immense Structural Rigidity and Stability

Bed Structure: Crafted from high-quality cast iron or welded steel, key components like the bed and base are reinforced with ribs, ensuring exceptional strength and stability despite the immense workpiece and cutting forces, fundamentally guaranteeing machining accuracy.

2. Spindle System: Equipped with an oversized, highly rigid spindle box and heavy-duty spindle bearings, they provide exceptional torsional rigidity and load-bearing capacity.

3. Powerful Drive Power and Torque

Equipped with a high-power spindle motor and servo motor, they deliver impressive cutting torque. This enables them to perform heavy-duty roughing operations with high stock removal on large forgings and castings, efficiently removing excess stock.

4. Excellent Load-Bearing Capacity: Utilizing a high-strength chuck, steady rest, and tailstock, along with specially reinforced bed guideways, they are capable of stably supporting and rotating workpieces weighing tens of tons. 5. Ability to Meet Special Machining Requirements

Vibration Resistance: Specially designed to suppress vibrations that may occur during heavy cutting, ensuring excellent surface quality during both roughing and finishing.

6. Thermal Deformation Control: Due to the long machining cycles that generate significant heat, heavy-duty CNC lathes are typically equipped with comprehensive cooling and thermal compensation systems to minimize the impact of thermal deformation on precision.

7. High Level of Automation and Intelligence

Modern heavy-duty CNC lathes are often equipped with automatic tool magazines, in-machine tool setters, workpiece measurement systems, and even automated loading and unloading robots to reduce worker workload and improve safety when machining extremely large workpieces.



Application

Heavy-duty CNC lathes are indispensable "machine tools" in the manufacturing of major technical equipment, primarily used in the following applications:

1. Energy Equipment Manufacturing

Hydropower: turbine main shafts, rotors, and mirror plates.

Thermal/Nuclear Power: Turning of steam turbine rotors, generator main shafts, and the inner wall of nuclear reactor pressure vessels.

Wind Power: Turning of large wind turbine main shafts and gearbox components.

2. Shipbuilding

Marine diesel engines: Large crankshafts, camshafts, and cylinder liners.

Propulsion systems: Propeller shafts and rudder stocks.

3. Metallurgical and Mining Equipment: Rolling mill rollers, large gear blanks, and drive shafts for mining machinery.

4. Aerospace and Defense: Rocket engine casings, large rings, landing gear outer barrels, tank gun barrels, etc.

5. Large Construction Machinery: Excavator slewing bearings and hydraulic cylinders, etc.
