The SHANDONG SANZHENG CW6163B/5000 is a heavy-duty manual lathe designed for precision turning operations on medium to large workpieces. With a maximum swing diameter of 630mm (24.8 inches) over the bed, this machine accommodates substantial cylindrical workpieces and enables efficient machining of internal and external surfaces. The extended center distance of 5000mm (196.9 inches) provides flexibility for various workpiece lengths, making it suitable for batch production and custom fabrication work. The spindle features a 104mm bore (approximately 4.1 inches) with a Morse No. 5 taper, allowing secure tool and workpiece holding while maintaining dimensional accuracy. The machine operates at spindle speeds ranging from 7.5 to 1,000 RPM with 18 graduated speeds, enabling optimization for different material properties and cutting requirements. Powered by an 11 kW main motor (approximately 14.8 HP), the lathe delivers consistent torque for heavy cutting operations. The swing over the carriage measures 350mm (13.8 inches), accommodating larger diameter workpieces during tool engagement. A reinforced composite bed structure with double finning plates enhances rigidity and precision, reducing vibration during operation. The machine includes rapid carriage movement at 4,000 mm/min for efficient tool positioning and features both hand and foot brake options for operator safety and control. Threading capabilities encompass metric, inch, module, and diametral pitch systems, supporting diverse manufacturing requirements across different measurement standards.
