MFG CK5231 Heavy-Duty Double Column CNC Vertical Turning Lathe (VTL)

3150mm Swing, 25-Ton Load Capacity & Dual Turrets for Massive Industrial Components

Product Overview
The MFG CK5231 is a monumental gantry-style, double-column CNC Vertical Turning Lathe (VTL) engineered to dominate the largest and heaviest machining applications in the heavy industry sector.

Designed with CAD-optimized structural integrity, this machine effortlessly accommodates ultra-heavy workpieces weighing up to 25 tons with a maximum machining diameter of 3150mm (3.15 meters).

Powered by a massive 55kW servo main motor paired with a 4-speed stepless transmission, the CK5231 delivers devastating low-end torque for aggressive roughing and smooth, vibration-free rotation for mirror-finish precision.

Equipped with a highly advanced dual-turret, dual-channel architecture—featuring Siemens 828D and Beijing Super-Synchronous CNC systems—this VTL is the ultimate turnkey solution for the wind power, aerospace, mining, and heavy valve industries.

Key Features & Advanced Engineering

• Colossal 3.15-Meter & 25-Ton Capacity: The massive 2830mm worktable is expertly engineered to support ultra-heavy payloads up to 25 tons. The double-column gantry architecture ensures uncompromising static and dynamic rigidity, allowing for the highly stable machining of components up to 3150mm in diameter and 2000mm in height.
• Dual-Turret & Dual-System Productivity: Designed for complex, multi-process manufacturing. The Left Turret is governed by the industry-leading Siemens 828D CNC system, while the Right Turret features a DVT structure controlled by the highly reliable Beijing Super-Synchronous control system. This independent dual-channel setup drastically reduces cycle times on massive parts.
• 55kW Servo Drive with 4-Speed Transmission: The headstock is driven by a powerhouse 55kW AC servo motor coupled with a 4-gear mechanical gearbox. This provides fully stepless speed regulation within each gear range, ensuring maximum torque output for heavy material removal and high rotational accuracy with remarkably low noise.
• Gantry-Style Double-Column Rigidity: The symmetrically designed cast-iron frame absorbs immense cutting forces. This optimized double-column structure completely minimizes deflection and thermal distortion during heavy interrupted cuts on tough alloys, ferrous metals, and non-ferrous materials.
• Versatile Machining Capabilities: Perfectly suited for processing diverse industrial materials, the CK5231 excels at executing rough and finish turning of internal/external cylindrical and conical surfaces, planes, intricate arcs, complex revolving curved surfaces, and deep annular grooves.
