The CK6140B CNC Lathe is a high-performance horizontal metal turning machine designed for precision machining and versatile applications. Equipped with a 250mm chuck, 420mm swing over bed, and 750mm machining length, it offers exceptional rigidity, stability, and cutting accuracy.
Powered by a 7.5kW main motor and a 3-speed stepless spindle (60-2000rpm), the CK6140B ensures smooth and efficient operation across various materials and complex workpieces. The 58mm spindle bore and D-6 nose provide excellent compatibility for larger parts and bars.
The machine comes with an electric 4-position tool turret and robust tailstock (MT4 taper) for stable support and flexible tooling. Its compact footprint (2200×1400×1700mm) and optimized layout make it ideal for both small workshops and industrial production lines.
Whether you're manufacturing shafts, flanges, or custom components, the CK6140B delivers consistent, high-quality results for a wide range of metalworking tasks.
High precision and reliable performance
Wide spindle speed range for multi-material processing
Compact design with a strong cutting capacity
Ideal for automotive, aerospace, mold-making, and general machining
