JINAN FIRST C6140/1000 MANUAL LATHE

The JINAN FIRST C6140/1000 is a horizontal manual lathe machine engineered for versatile metal working operations. This precision instrument features a maximum swing over bed of 400mm (15.75 inches) and a center distance of 1000mm (39.37 inches), making it suitable for medium-scale turning applications on steel, cast iron, and nonferrous metals. The machine is equipped with a spindle bore of 52mm (2.05 inches) with MT6 taper, providing reliable workholding capabilities for various turning operations. Powered by a 5.5kW (5.36 HP) motor, the lathe delivers robust performance with spindle speeds ranging from 36 to 1400 RPM across nine steps, accommodating diverse machining requirements. The swing over cross slide of 240mm (9.45 inches) facilitates efficient positioning of cutting tools for internal and external cylindrical turning, conical surfaces, and end face operations. The cross slide travel extends 200mm with a compound rest travel of 150mm, enabling precise tool positioning and depth control. This machine supports metric threads ranging from 0.5-14mm, inch threads from 2-40 per inch, and modular threads from 0.25-3.5mm, providing threading versatility. The 20×20mm tool shank accommodates standard cutting tools, while the tailstock features a 75mm diameter sleeve with MT5 taper and 160mm travel. Built with hardened, precision-ground steel gears and a rigid cast iron construction weighing 1700kg, the C6140/1000 achieves dimensional accuracy to IT7 level with smooth surface finishes suitable for precision manufacturing operations.
