ACRA 21120C MANUAL LATHES

Technical Description

The ACRA 21120C manual lathe is a precision-engineered heavy-duty machine designed for large-scale turning operations. It features a 21-inch swing over the bed with a 120-inch distance between centers, enabling machining of long workpieces. The lathe is powered by a robust 12.5 horsepower spindle drive motor capable of reaching up to 1,600 RPM across 16 speed steps, optimizing versatility for various materials and cutting requirements. The spindle bore diameter measures 3.125 inches, allowing the passage of sizeable bar stock through the spindle, increasing setup flexibility. The swing over the cross slide is 14 inches, providing ample clearance for tool post and workpiece interference during cross feeds. The cross slide travel is approximately 11 inches, with compound slide travel around 5 3/8 inches, facilitating precise tool positioning. The lathe incorporates features such as a clutch and rapid travel mechanisms for improved operational efficiency. It is designed with a gap bed to accommodate larger diameter workpieces and includes provisions for steady and follow rests, coolant system, and a four-position tool post for diverse tooling options. The machine supports inch thread ranges from 2 to 72 TPI, enhancing threading versatility. Its 230/460V three-phase power supply ensures consistent torque delivery for demanding machining tasks. Overall, the ACRA 21120C manual lathe combines substantial swing and center distance with powerful motor and precision features, making it suitable for industrial applications requiring large, accurate turning work.
