MFG CK5240 Heavy-Duty Double Column CNC Vertical Turning Lathe (VTL)

4000mm Swing, 20-Ton Load Capacity & Dual Systems for Massive Industrial Components

Product Overview
The MFG CK5240 (CK5240x25/20) is a colossal gantry-style, double-column CNC Vertical Turning Lathe (VTL) explicitly engineered to dominate the 4-meter ultra-heavy machining class.

Designed with CAD-optimized structural integrity, this machine easily accommodates massive workpieces weighing up to 20 tons, with a maximum machining diameter of 4000mm (4 meters) and a turning height of 2500mm.

Powered by a devastating 55kW servo main motor paired with a 4-speed stepless transmission, the CK5240 delivers crushing low-end torque for aggressive roughing.

Equipped with highly rigid square rams and an advanced dual-system architecture—featuring Siemens 828D on the right and a DVT system on the left—this VTL is the ultimate turnkey solution for the shipbuilding, wind energy, aerospace, and heavy mining industries.

Key Features & Advanced Engineering

• Colossal 4-Meter & 20-Ton Capacity: The massive 3200mm worktable is expertly engineered to support ultra-heavy payloads up to 20 tons with absolute stability. The double-column gantry architecture ensures uncompromising static and dynamic rigidity, allowing for the machining of massive components up to 4000mm in diameter without deflection.
• Dual-Turret & Dual-System Productivity: Designed to slash cycle times on giant components. The Right Turret is governed by the industry-leading Siemens 828D CNC system (with precise 2-axis control), while the Left Turret utilizes a reliable DVT structure. This independent dual-channel setup allows for simultaneous multi-process manufacturing.
• 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.
• Heavy-Duty Square Ram Architecture: Both vertical rams utilize a highly rigid 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 on tough alloys.
• Operator Ergonomics & Safety: Operating a 4-meter machine requires specialized ergonomics. The CK5240 is equipped with an elevating crossbeam featuring a specialized traveling table/platform for operator access, paired with a suspended ergonomic control pendant for safe, intuitive, and immediate machine control from any vantage point.
• Versatile Machining Capabilities: Perfectly suited for processing ferrous metals, non-ferrous alloys, and non-metallic materials. It excels at rough and finish turning of internal/external cylindrical and conical surfaces, planes, intricate arcs, complex rotary curved surfaces, and deep annular grooves.
