CK630H CNC Lathe - Heavy-Duty Precision for Large Workpiece Machining

The CK630H CNC Lathe is a robust and high-performance machining solution engineered to excel in heavy-duty turning operations for large and complex workpieces. Combining exceptional rigidity, versatile capabilities, and advanced design, it is ideally suited for industries such as energy, aerospace, heavy equipment manufacturing, and automotive, where precision and reliability are critical.
With a maximum swing diameter over the bed of φ630mm and over the slide of φ410mm, the CK630H can accommodate oversized workpieces with ease. Its X-axis (transverse) maximum stroke of 420mm and flexible machining length options (500/1000/1500/2000/3000/4000/5000mm) ensure adaptability to a wide range of component sizes, from short shafts to long cylindrical parts.
At the core of its performance is a powerful spindle system: featuring an A2-8 spindle nose and options for φ82mm or φ105mm spindle bores (both with Metric No.90 (1:20) inner hole tapers), the lathe supports compatibility with various tooling and workholding setups, enabling efficient chip evacuation and stable machining. The spindle speed range of 50-2000rpm allows for optimized cutting parameters across diverse materials, from high-strength steel to aluminum alloys.
Structurally, the CK630H is built for stability and durability. It includes a 400mm-wide bed guide with a one-flat and one V-shape guideway design, minimizing vibration and ensuring precise movement during high-load operations. The integral bed feet further enhance rigidity, while the 7.5/11kw spindle motor delivers consistent power for demanding cutting tasks.
Equipped with a turret offering vertical 4 positions and horizontal 6 positions, the lathe enables quick tool changes and versatile machining sequences, reducing setup time and improving productivity. A 250mm standard chuck (with optional configurations) secures workpieces firmly, and the φ75mm tailstock sleeve with Morse No.5 taper provides additional support for long workpieces, ensuring accuracy throughout the machining process.
While specific precision metrics (e.g., repeat positioning accuracy, roundness) are not listed, the CK630H’s robust construction and high-quality components prioritize stability and performance, making it a trusted choice for heavy-duty manufacturing environments. Whether processing large shafts, cylinders, or custom components, this lathe balances power and precision to meet the most challenging industrial demands.
