HMT NH22 MANUAL LATHE

Technical Description

The HMT NH22 Manual Lathe is a robust precision machine featuring a swing capacity of 19.69 inches and between-centers options of 39.37 and 59.06 inches, enabling versatile workpiece handling. Powered by a 15 HP motor, it achieves a maximum spindle speed of 2,030 RPM across 16 selectable speeds, providing flexible machining conditions for diverse applications. The lathe’s construction includes a rigid rectangular wide bed with induction-hardened integral guideways and short spindles and shafts to maximize drive rigidity and minimize thermal deformation. It is equipped with a 13.78-inch 14” dog chuck for secure workholding, complemented by both steady and follow rests to support long or thin workpieces, enhancing machining accuracy. The quick change tool post facilitates efficient tool swaps, while the integrated coolant system ensures thermal stability and improved tool life during cutting operations. The machine measures 11 by 4 feet and weighs approximately 8,818 pounds, reflecting its heavy-duty build suitable for industrial environments. Additional features include case-hardened and ground headstock gears operated via a dry sump lubrication system to maintain consistent performance and reduce wear. The center height on the bed is 8.66 inches, enabling precise alignment and turning operations. This lathe is engineered for high speed and precision machining tasks, making it ideal for toolroom, manufacturing, and maintenance use where rigidity, accuracy, and operational versatility are critical.
