SPARK CK61100E/8000 MANUAL LATHES

Technical Description

The SPARK CK61100E/8000 Manual Lathe is a heavy-duty lathe designed for large and precise metal turning applications. It features a maximum swing of 39.37 inches (1000 mm) over the bed, enabling machining of large-diameter workpieces. The distance between centers is 315 inches, supporting long workpiece lengths. Its spindle bore diameter measures 3.94 inches (approximately 100 mm), allowing for substantial stock to pass through the spindle. Powered by a robust 40.36 HP motor, the lathe achieves spindle speeds up to 200 RPM, suitable for heavy cutting tasks. The machine operates under CNC control, offering precise and automated machining capabilities. The lathe construction utilizes high-quality cast iron with hardened and ground bed rails for superior rigidity and resistance to deformation during heavy cutting. The bed width typically measures 600-650 mm, enhancing the machine’s stability. It supports a maximum workpiece weight of up to 2 tons, emphasizing its capacity for heavy-duty operations. The spindle operates with a C11 nose and a taper of 1:20 (Metric 120), equipped with a 4-station electrical turret for tool changes and a manual tailstock with a 250 mm sleeve travel and Morse taper 6. The lathe delivers high positioning accuracy, repeatability, and surface finish quality (Ra1.6). Its dimensions and weight support stable operation in manufacturing and repair shop environments. Additional features include rapid traverse speeds of 4000 mm/min (X-axis) and 5000 mm/min (Z-axis), and an automatic lubrication system. This machine is suitable for precision machining of large shafts, heavy components, and complex geometries in industrial settings.
