MFG Machinery CK51125A CNC Vertical Turning Lathe (VTL)

Fixed Crossbeam, Square Ram & 12-Station ATC for Heavy Deep-Hole Machining

Product Overview
The MFG Machinery CK51125A is a highly rigid, full-function single-column CNC Vertical Turning Lathe (VTL) engineered for uncompromising stability.

Distinguishing itself from standard liftable-beam models, the "A" series features a massive fixed crossbeam and a heavy-duty square ram.

This unique architectural combination eliminates beam deflection, providing the ultimate structural rigidity required for aggressive heavy cutting and deep-hole boring operations. Equipped with a rapid 12-station Automatic Tool Changer (ATC) and a 2-speed gearbox, the CK51125A minimizes non-cutting idle times while maximizing torque.

Designed for seamless integration with optional large-format hydraulic chucks, it is the premier solution for the automated, high-precision machining of heavy disc sleeves, covers, and large cylindrical components.

Key Features & Advanced Engineering

• Ultra-Rigid Fixed Crossbeam Architecture: The base, column, and crossbeam are cast from premium high-strength iron into a symmetrical box-type structure. The fixed crossbeam design inherently provides superior structural stiffness and vibration damping compared to moving beams, guaranteeing absolute precision during the heaviest interrupted cuts.
• Heavy-Duty Square Ram for Deep Boring: The vertical ram utilizes an optimized square cross-section design. This geometry maximizes bending stiffness and minimizes deflection, giving the machine a distinct and obvious advantage when executing high-precision deep-hole boring and internal profiling.
• 12-Station Automatic Tool Changer (ATC): Maximizing your continuous production capabilities. The machine is equipped with a high-capacity 12-station tool magazine. It delivers exceptionally fast and reliable automated tool changes, drastically reducing cycle times on complex, multi-process parts.
• High-Torque 2-Speed Spindle Drive: Powered by a high-capacity AC spindle motor paired with a robust two-stage gearbox. This transmission setup delivers massive cutting torque at low speeds for aggressive roughing, while maintaining smooth, stable rotation at high speeds for fine finishing.
• Hydraulic Workholding Ready: Designed for high-efficiency production, the machine fully supports optional large-sized hydraulic chucks and rotary oil cylinders. This allows for automated, convenient, and incredibly secure workpiece clamping, reducing operator fatigue and setup times.
• Anti-Stick-Slip Hardened Guideways: The large-span machine guideways are induction-hardened, precision-scraped, and meticulously ground. They are lined with a high-performance PTFE (Turcite-B) anti-friction coating to eliminate stick-slip, ensuring remarkably low sliding resistance and long-term precision retention.
• Integrated Thermal Management: The main drive system is equipped with a dedicated spindle oil cooler to ensure optimal continuous lubrication and prevent thermal expansion during prolonged heavy-duty machining shifts.
