KAIDA CW61140C/1.5 MANUAL LATHE

Technical Description

The KAIDA CW61140C/1.5 is a heavy-duty manual lathe designed for large-scale and precision turning operations. It features a **maximum swing diameter of 55.12 inches (1400 mm)** over the bed and a **distance between centers of 59.06 inches (1500 mm)**, accommodating substantial workpieces up to 1.5 meters in length. The lathe is equipped with a **spindle bore of 5.12 inches (130 mm)** with a metric taper of Φ140 1:20, ensuring compatibility with large-diameter tooling and workpieces. Its spindle system is supported by precision roller bearings, offering high rigidity and accuracy essential for heavy-duty machining. The spindle speed ranges from 2.5 to 250 RPM across 24 normal and 12 reverse steps, powered by a **29.57 HP (22 kW) motor**, allowing controlled operation suited for large diameter and heavy components. The machine bed is robust at 755 mm wide, providing stability during heavy cuts. Longitudinal and cross-slide travels enable versatile tool positioning, with rapid feed available on the apron. The tool post supports a feed rate of up to 935 mm/min, and the lathe supports metric thread pitches from 1 to 120 mm, Whitworth threads, module threads, and diametral pitch threads, making it capable of diverse threading operations. Additional features include a rapid feed motor (1.5 kW) and a coolant pump (0.25 kW) to maintain machining efficiency and workpiece integrity. This lathe is ideal for machining large, heavy workpieces where precision and durability are critical.
