The SPARK CK61100E/1500 is a heavy-duty CNC manual lathe designed for large-scale machining tasks. It features a maximum swing over bed of 1000 mm (39.37 inches) and a maximum distance between centers of 1500 mm (59.06 inches), accommodating substantial workpieces. The spindle bore measures 100–105 mm (around 3.94 inches), allowing for large bar stock or workpieces to pass through the spindle. Powered by a robust 40.24 HP (approximately 30 kW) spindle motor, it delivers high torque for heavy cutting operations. The spindle speed is adjustable up to 200 RPM in this configuration, though variants offer wider speed ranges with smooth gear transitions. The lathe bed is constructed from high-quality, precision-ground cast iron with a width of 600-650 mm, ensuring rigidity and vibration resistance for heavy-duty turning. The machine employs a manual CNC control interface, giving operators both precision and flexibility during operation. Additional features typically include a vertical 4-station tool post or optional multi-station turrets, hardened guideways for durability, and a tailstock with a quill diameter around 100 mm and travel of 250 mm, supporting long and heavy workpieces. With dimensions roughly 3700 x 2050 x 1800 mm and a weight around 7000–7700 kg, the CK61100E/1500 is engineered for stable, high-precision machining in demanding industrial environments. This lathe is suitable for machining large shafts, heavy metal parts, and components requiring both power and accuracy under manual CNC operation.
