MFG Machinery CK5112 CNC Vertical Turning Lathe (VTL)

1250mm Swing, 3-Ton Load Capacity & Siemens 828D for Heavy-Duty Precision Machining

Product Overview
The MFG Machinery CK5112 is a heavy-duty, single-column CNC Vertical Turning Lathe (VTL) engineered to deliver massive cutting power and unwavering precision.

Designed for the rigorous demands of processing ferrous, non-ferrous, and non-metallic workpieces, it easily accommodates large-scale components weighing up to 3000 kg.

Powered by a premium 22kW servo motor paired with a 4-speed automatic gearbox, it generates an immense 12,000 Nm of worktable torque.

Guided by the highly advanced Siemens 828D CNC system and featuring a hydraulically supported worktable, the CK5112 excels in roughing and high-precision finishing of internal/external cylinders, conical profiles, and complex grooving, making it an indispensable asset for the aerospace, valve, and heavy machinery industries.

Key Features & Advanced Engineering

• Hydraulic-Supported High-Precision Worktable: The massive 1000mm worktable is engineered with radial and annular reinforcing ribs for maximum shock absorption. The base utilizes a hydraulic guide rail support system combined with two sets of NN-series tapered-bore double-row cylindrical roller bearings. This allows operators to pre-tighten the clearance, ensuring extremely high rotary precision and floating stability based on the workpiece weight.
• Heavy-Duty Induction-Hardened Bed: Cast from high-strength, low-stress iron and subjected to comprehensive thermal aging stress-relief annealing. The guideways are precision-ground and high-frequency induction hardened to HRC 48-55, guaranteeing exceptional wear resistance and long-term dynamic rigidity.
• Hydraulic Locking Crossbeam: The crossbeam is elevated via a heavy-duty T-type lead screw and worm gear box. Once positioned, an automated hydraulic wedge-block clamping mechanism firmly locks the crossbeam to the column, eliminating any vibration during aggressive cuts. Dual limit devices (mechanical and electrical soft limits) ensure absolute operational safety.
• High-Dynamic Servo Tool Post: The vertical ram (tool post) delivers rapid horizontal (X-axis) and vertical (Z-axis) feeds powered by independent servo motors. Force is transmitted through precision planetary reducers and heavy-duty ball screws to ensure flawless contouring accuracy.
• 22kW 4-Speed Stepless Transmission: Driven by a massive 22kW servo motor, the main transmission utilizes an electromagnetic slide-valve gearbox to realize 4-gear stepless speed regulation (6.3 - 200 r/min). The internal transmission gears are crafted from 42CrMo steel, high-frequency quenched (HRC 40-45), and ground to Level-6 precision for whisper-quiet, jump-free operation.
• In-House Engineered Electrical System: Unlike many competitors, our electrical control cabinets are 100% designed, constructed, and commissioned in-house (non-outsourced). Fully compliant with IEC 60204-1 and ISO 13849-1 standards, this guarantees uncompromising electrical reliability, safety interlocks, and rapid after-sales support.
• Siemens 828D CNC Integration: Centered around a suspended, highly ergonomic operator console, the industry-leading Siemens 828D system manages multi-axis synchronization, tool compensation, automated lubrication, and robust self-diagnostic functions.
