AMERICAN TURNMASTER POWER SIX-70 MANUAL LATHES

Technical Description

The American Turnmaster Power Six-70 is a heavy-duty manual lathe designed for large-scale precision machining. It features a 70.2-inch swing capacity and a substantial 6.0-inch spindle bore, enabling it to accommodate and machine large workpieces with ease. Powered by a robust 40 HP motor, the lathe offers a maximum spindle speed of 600 RPM, providing sufficient torque and speed control for heavy cutting operations. The swing over the cross slide measures 55.0 inches, supporting versatility in turning tasks. Its construction includes a massive one-piece floor-type bed and base for exceptional rigidity and vibration damping, critical for maintaining accuracy during heavy cuts. The machine’s spindle nose and internal components are engineered for durability and reliability under demanding workloads. Additional features typically associated with this series, though not specified in this exact model, include hydraulic control on tailstock movement, automatic lubrication, and provisions for flood coolant systems to enhance tool life and surface finish. This lathe is suited for industries requiring large-scale, precise turning such as oil and gas, heavy machinery, and aerospace, where rigid support and high power are essential. Its design balances power, capacity, and control, making it a reliable choice for shop environments handling extensive, heavy-duty machining applications.
