HMT MACHINE TOOLS NH22/3000 MANUAL LATHES

Technical Description

The HMT NH22/3000 is a precision manual lathe designed for versatile machining operations. Built with a rigid rectangular section bed and short spindle configuration, this machine delivers maximum drive rigidity and minimizes thermal deformation through dry sump lubrication. The lathe features a 19.69-inch swing diameter with 118.11 inches between centers, accommodating a wide range of workpiece sizes. Its 2.09-inch spindle bore with Type A2-6 nose accepts various tooling options, while the 10.63-inch swing over cross slide enables precise lateral positioning. Operating at a maximum of 2,040 RPM with a powerful 14.75 HP main motor, the machine delivers robust cutting capability across multiple speed ranges. The spindle speeds range from 40 to 20,400 RPM, providing flexibility for different material and finishing requirements. All drive gears in the headstock are case-hardened and ground for durability and accuracy. The lathe includes longitudinal and cross feeds ranging from 0.04-2.24 mm/rev and 0.02-1.12 mm/rev respectively, ensuring fine control during precision work. With MT5 taper tailstock, quick-change tool post with five holders, and 60° dead centers, this machine supports comprehensive turning, facing, and boring operations. Weighing approximately 2,230 kg with induction-hardened integral guideways, the NH22/3000 combines durability with precision manufacturing capability for production and toolroom environments.
