MFG CK5250 Ultra-Heavy Double Column CNC Vertical Turning Lathe (VTL)

5000mm Swing, 50-Ton Load Capacity & 90kW Servo Drive for Massive Industrial Components

Product Overview
The MFG CK5250 is an ultra-heavy-duty, gantry-style double-column CNC Vertical Turning Lathe (VTL) engineered to conquer the absolute limits of industrial manufacturing.

Designed for the nuclear, aerospace, shipbuilding, and massive wind-energy sectors, this colossal machine accommodates workpieces up to 5000mm (5 meters) in diameter and 4500mm in height, with an astonishing maximum worktable load of 50 Tons.

Powered by a devastating 90kW servo main motor and a 2-speed vertical gearbox, it delivers crushing torque for aggressive material removal.

Featuring extreme-rigidity 260x260mm square rams, steel-inlaid guideways, and a dual-system control architecture (Siemens 828D & Beijing Chaotong), the CK5250 provides unwavering stability and precision for your most massive machining challenges.

Key Features & Advanced Engineering

• Colossal 5-Meter & 50-Ton Payload Capacity: The massive 4500mm worktable is expertly engineered to support extreme payloads up to 50 tons (50,000 kg). The double-column gantry architecture ensures uncompromising static and dynamic rigidity, allowing for the highly stable machining of massive 5000mm components without any structural deflection.
• Dual-Turret & Dual-System Productivity: Designed to slash cycle times on giant components. The Left Tool Post is governed by the industry-leading Siemens 828D CNC system (2-axis control), while the Right Tool Post utilizes a robust DVT structure controlled by the highly reliable Beijing Chaotong system. This independent setup allows for simultaneous multi-process manufacturing.
• 90kW Servo Drive with 2-Speed Vertical Gearbox: The headstock is driven by a powerhouse 90kW Beijing Chaotong AC servo motor coupled with a 2-speed vertical mechanical gearbox. This provides flexible, stepless speed regulation, ensuring maximum torque output for heavy roughing and high rotational accuracy with remarkably low noise for finishing.
• Ultra-Rigid 260x260mm Square Rams: Both vertical rams utilize a massively oversized 260x260mm square cross-section design. This geometry maximizes bending stiffness and provides superior vibration damping, which is essential for maintaining tight tolerances during deep-hole boring and heavy interrupted cuts.
• Extreme-Durability Guideway Engineering: Built for decades of abuse under 50-ton loads. The upper guide surface of the crossbeam is exclusively inlaid with hardened steel plates, and all sliding gibs are crafted from premium copper/bronze. This dramatically reduces friction, prevents galling, and ensures long-term precision retention.
• Operator Ergonomics & Machine Protection: Operating a 5-meter machine requires specialized ergonomics. The crossbeam is equipped with a movable slide table (traveling platform) to give operators safe, immediate access to the cutting zone. The crossbeam is also fully protected by heavy-duty stainless steel telescopic covers against chips and coolant.
