H.E.S. JUPITER 830 MANUAL LATHE

The H. Ernault Somua Jupiter 830 is a heavy-duty manual lathe engineered for versatile metalworking applications. This industrial-grade machine features a maximum swing of 31 inches over the bedways and 20 inches over the cross-slide, accommodating workpieces up to 830mm in diameter near the chuck. The spindle incorporates a 3-inch through hole, enabling through-spindle machining operations and accommodating large diameter stock. Operating at spindle speeds ranging from 10 to 1600 RPM, the lathe provides flexibility across various cutting applications and material types. Equipped with a 27-inch four-jaw chuck, the machine delivers reliable workpiece clamping for precision operations. The lathe supports both inch and metric threading, facilitating diverse manufacturing requirements. A quick-change toolpost enhances operational efficiency by enabling rapid tool exchanges without interrupting production flow. The machine is powered by a robust 20 HP electric motor operating at 220 volts, providing sufficient power for demanding machining tasks. Standard equipment includes integrated chip pans for effective coolant and chip management. Additional features include three steady rests, a coolant pump system, and a foot-operated brake for enhanced safety and operational control. The machine's center height of 400mm and maximum job length of 1500mm accommodate medium to large workpieces typical in production environments. Originally manufactured by H. Ernault Somua of France, this lathe represents precision European engineering designed for long-term industrial service.
