HMT MACHINE TOOLS NH22/1000 MANUAL LATHES

Technical Description

The HMT NH22/1000 is a robust manual engine lathe designed for heavy-duty precision machining with a maximum swing over bed of 19.69 inches (500 mm) and a center distance of 39.37 inches (1000 mm). It features a spindle bore diameter of 2.09 inches (53 mm), enabling the accommodation of larger workpieces. The lathe is powered by a 14.75 HP motor, delivering up to 2,040 RPM spindle speed, facilitating a wide range of machining operations. The swing over the cross slide measures 10.63 inches (270 mm), allowing for versatile tool positioning and workpiece handling. Constructed with a rigid rectangular section wide bed and induction-hardened integral guideways, it ensures high rigidity and thermal stability during continuous operation, minimizing deformation. The spindle and drive shafts are short for maximum drive rigidity, with case-hardened and ground gears within the headstock for smooth power transmission. The machine includes a dry sump lubrication system to enhance operational efficiency and longevity. It supports forward and reverse spindle speed ranges of 40-2040 RPM and 60-1430 RPM respectively, with longitudinal feed variations to suit precision requirements. Equipped with a 3-jaw self-centering chuck and a quick-change tool post supporting multiple tool holders, it allows for efficient tooling changes. Overall, the HMT NH22/1000 is engineered for durability, precision, and continuous heavy-duty use in various engineering and manufacturing applications. It weighs approximately 2230 kg and measures about 2550 x 1350 x 1700 mm (LxWxH), suitable for demanding workshop environments.
