U.S. INDUSTRIAL 21 X 120 MANUAL LATHES

Technical Description

The U.S. Industrial 21 x 120 Manual Lathe is a heavy-duty engine lathe designed for precision turning of large workpieces, featuring a 21-inch swing and 120-inch distance between centers. The lathe is equipped with a robust headstock and tailstock, supporting a wide range of machining applications. It offers both inch and metric threading capabilities, allowing for versatile thread cutting to meet various industry standards. The machine is fitted with a 12-inch 3-jaw chuck for secure workholding, a steady rest for added support during long turning operations, and a tool holder for efficient tool management. Additional features include a taper attachment for accurate taper turning, chip pans for easy swarf removal, a coolant system to maintain optimal cutting temperatures, and a work light for improved visibility at the cutting zone. The lathe’s design emphasizes durability and ease of use, with a gap-bed configuration that accommodates larger diameter workpieces. The spindle speed is listed as 371,500 RPM, though this value is likely a typographical error, as typical industrial lathes operate at much lower speeds; actual spindle speeds for similar models generally range from 18 to 1800 RPM. The machine’s construction ensures stability and accuracy, making it suitable for demanding industrial environments. All components are designed for reliable performance, ease of maintenance, and operator safety.
