LUNAN LUNAN-1640 MANUAL LATHES

Technical Description

The LUNAN-1640 is a precision horizontal engine lathe designed for general-purpose turning, threading, and facing operations. This gap-bed lathe features a maximum swing over bed of 400mm (15.75 inches) with an enhanced swing over gap of 590mm (23 inches), enabling machining of larger diameter workpieces. The center distance spans 1000mm (39.37 inches), accommodating mid-range workpiece lengths, while the bed width of 300mm provides stable support during operations. The spindle bore measures 58mm (2.28 inches) with a camlock nose configuration, supporting standard tooling interfaces. Operating at spindle speeds from 50 to 2000 RPM across 12 steps, the lathe delivers variable speed capability for diverse material and operation requirements. The cross slide swing reaches 210mm (8.27 inches), facilitating access for tooling and workpiece manipulation. Driven by a 4KW motor, the lathe provides adequate power for efficient machining of materials including steel, aluminum, and brass. The precision construction incorporates a high-tensile cast iron bed manufactured through resin-sand foundry processes, with hardened and ground bedways, gears, and shafts ensuring dimensional stability and longevity. The lathe's net weight of 1800kg reflects robust construction suitable for industrial workshop environments. ISO9001:2000 and CE certifications confirm quality and safety standards compliance, making this lathe an economical solution for small to medium-scale production and job shop applications requiring reliable precision turning capabilities.
