MFG Machinery CK6140Q High-Precision Flat Bed CNC Lathe

Φ400mm Swing, Widened Carriage for Heavy-Duty Cutting & HRC45+ Induction Hardened Guideways

Product Overview
The MFG Machinery CK6140Q is a high-performance, flat-bed CNC lathe meticulously engineered for workshops requiring a perfect balance of precision and aggressive material removal.

Distinct from standard 40-series lathes, the CK6140Q features an optimized high-strength, widened carriage that provides superior structural rigidity for heavy-duty cutting. Built upon a 320mm wide bed with induction-hardened guideways (HRC45+) and precision ball screw transmission, this machine ensures exceptional dynamic stability and long-term accuracy.

Whether machining complex shafts or large-diameter disc components, the CK6140Q is the ultimate high-efficiency solution for demanding industrial production.

Key Features & Engineering Advantages

• Enhanced Rigidity with Widened Carriage: The CK6140Q is specifically designed with a reinforced and widened carriage assembly. This architectural upgrade significantly enhances the machine's damping capacity and structural stiffness, enabling stable, heavy-duty cuts while maintaining a superior surface finish.
• HRC45+ Induction Hardened Guideways: The machine bed is cast from premium wear-resistant iron, with guide surfaces treated via intermediate frequency induction quenching. Achieving a hardness of HRC45 or above, these guideways guarantee decades of wear resistance and pinpoint accuracy retention.
• High-Precision Spindle & Transmission: Equipped with high-precision rolling bearings and premium ball screw transmission, the spindle delivers low-noise operation and high torque even at its maximum speed of 2,500 rpm. This ensures flawless repeat positioning and excellent dynamic performance.
• Frequency Conversion Stepless Speed Control: Features an advanced VFD (Variable Frequency Drive) system for seamless, stepless speed regulation. Operators can instantly optimize cutting speeds for different materials and diameters, maximizing tool life and throughput.
• Rapid 4-Station Electric Turret: The standard 4-position electric turret provides fast, reliable, and precise tool indexing, allowing for the efficient execution of complex, multi-process turning operations in a single setup.
• Flexible Workholding Solutions: Comes standard with a high-durability manual chuck, with an optional hydraulic chuck system available for facilities looking to implement high-speed, automated production cycles.

Primary Applications

The CK6140Q is an exceptionally versatile workstation, ideally suited for turning internal/external cylinders, cones, arcs, and various Metric/Inch threads across diverse industries:

• Valves & Sanitary: High-precision valve bodies, plumbing fixtures, and sealing components.
• Automotive & Motorcycle: Engine sleeves, connecting rods, and axle components.
• Instruments & Bearings: Precision bearing rings and high-tolerance instrument housings.
• Electrical Appliances: Hardware connectors and complex metal housings.
