YUNNAN CY CW62125B/1500 MANUAL LATHES

Technical Description

The YUNNAN CY CW62125B/1500 manual lathe is a heavy-duty engine lathe designed for precision and robust metal turning applications. It features a maximum swing over the bed of 49.21 inches (1250 mm) and centers distance of 59.06 inches (1500 mm), allowing for machining of large workpieces up to 20 tons. The spindle bore is 5.12 inches (130 mm), accommodating substantial bar stock diameters. The lathe is powered by a 29.64 HP (22 kW) main motor and supports spindle speeds up to 315 RPM across 21 forward speed steps, with additional reverse speeds, enabling both high-speed and strong force turning operations. The bed width is around 755 mm, providing rigidity and stability during machining. The machine supports a variety of operations including internal and external turning, taper turning, end facing, threading (metric, inch, module, diametrical pitch), drilling, boring, grooving, and keyway broaching. The lathe bed is integrally cast and heat-treated (HT250), featuring high-frequency quenching and guide rail grinding to ensure precision and durability. The toolpost allows multiple feed rates and smooth longitudinal and cross feeds. The tailstock features an MT6 taper with ±25 mm travel. This model is suitable for machining cylindrical, conical, and disc parts of various materials with high-speed steel or carbide tooling. Rapid feed rates and load capacity of up to 6 tons enhance productivity and reliability for industrial manufacturing tasks.
