CK5250 CNC Double-Column JSkinston Heavy-Duty Vertical Lathe

1. Definition of the Basic Equipment

The CK5250 CNC double-column vertical lathe (hereinafter referred to as the “CNC vertical lathe”) is a large, heavy-duty vertical CNC cutting machine tool with a maximum machining diameter of 5,000 mm. It serves as the core equipment for machining extra-large-diameter heavy-duty parts such as discs and rings.

2. Key Structural Features

Double-column + crossbeam gantry frame: Two rigid columns on the left and right are paired with an integral crossbeam. The machine body has undergone finite element analysis (FEA) optimization, resulting in exceptional overall rigidity. It resists deformation under heavy-duty cutting loads, making it suitable for both heavy-allowance rough turning and high-precision finish turning;

Dual Independent CNC Tool Holders: One CK5250 CNC ram tool holder on each side (the blue enclosures on both sides of the image are labeled CK5250). These allow for simultaneous machining, significantly improving processing efficiency, and can also operate independently for separate machining operations;

Extra-large-diameter rotary table: The circular table at the base offers high load-bearing capacity, capable of clamping heavy workpieces weighing tens of metric tons. The table rotates with high precision to perform internal and external cylindrical turning as well as face turning;

CNC system control: Comes standard with a mainstream domestic CNC system (Siemens or Fanuc systems available as options). The X and Z axes feature servo drives, and automatic feed, thread cutting, and curved surface contouring can all be achieved through CNC programming.

3. Machining Capabilities

• Capable of machining workpieces made of metal materials such as cast steel, forged steel, cast iron, and stainless steel:
• Turning of inner and outer cylindrical surfaces and inner and outer conical surfaces
• Cutting of workpiece end faces, stepped surfaces, and grooves
• Forming of circular arcs and rotational surfaces
• Turning of standard cylindrical and tapered threads

The machine meets the dual requirements of rough machining—removing material with high cutting rates—and finish machining—ensuring dimensional tolerances and surface finish.

4. Major Application Industries

• Primarily used in the production of large components for the heavy industry sector:
• Wind power industry: wind turbine flanges, hubs, and gear ring bases
• Mining / Metallurgy: Roll end caps, large bearing housings, mining vehicle wheels
• Construction Machinery: Large hydraulic cylinder end caps, slewing bearing rings

Machining of heavy-duty disc-shaped components for the shipbuilding, power generation, and defense industries

5. Key Advantages and Highlights

Synchronous cutting with dual tool holders increases machining efficiency by over 40% compared to single-tool-holder vertical lathes;

Heavy-duty bed + hydrostatic rotary table, offering high load capacity, stable rotational accuracy, and minimal precision degradation over extended use;

Modular structural design for easy maintenance; milling capabilities and closed-loop grating scale systems can be added as needed;

Adapted to various domestic heavy industry workshop conditions, with dust resistance, resistance to coolant corrosion, and high durability.
