MONARCH SERIES 80 3220 MANUAL LATHES

Technical Description

The Monarch Series 80 3220 manual lathe is a heavy-duty precision machine designed for large workpieces and high-capacity turning operations. It features a robust 36-inch swing over bed ways and 25 inches over the cross slide, with a maximum distance between centers of 360 inches, enabling it to handle extensive lengths. Its spindle bore size is 3.5 inches, and it is powered by a 40 HP motor, delivering spindle speeds from 10 to 1,300 RPM for versatile machining applications. The lathe supports threading up to 1/2-28 TPI and can hold workpieces weighing up to 20,000 lbs between centers. Equipped with a 28-inch 4-jaw chuck, it facilitates precise, secure gripping of irregular or off-center parts. The Aloris tool post allows for quick tool changes and stable tool holding, enhancing machining accuracy. Additional features include hardened bed ways for durability, a 4-way rapid traverse for efficient tool movement, two steady rests to support long or slender workpieces and reduce deflection, and a tailstock for drilling and supporting workpieces during operation. Coolant system integration aids in temperature control and chip removal during cutting, while the taper attachment enables cutting of angled surfaces. The lathe’s design is suited to heavy machining tasks requiring high stability, accuracy, and capacity, making it ideal for industrial and toolroom use where large, heavy, and precise parts are manufactured.
