AMERICAN TURNMASTER POWER SEVEN-90 MANUAL LATHES

Technical Description

The American Turnmaster Power Seven-90 is a heavy-duty manual engine lathe engineered for large-scale production and heavy-duty machining operations, particularly in the oil and gas industry. This machine features an impressive 90.55-inch swing capacity with a 9.05-inch spindle bore, enabling the machining of substantial workpieces with exceptional power and rigidity. Powered by a robust 50 HP motor, the lathe operates at 600 RPM, delivering the torque necessary for demanding turning operations on large-diameter components. The 73-inch swing over cross slide provides substantial clearance for complex part geometries and offset machining applications. Built on Republic Lagun's signature 3-V-Way bed design, this lathe eliminates twisting and reversal error during extended turning operations on long shaft diameters, ensuring precision and repeatability. The machine incorporates a hardened and ground headstock with forged alloy steel spindle construction, featuring Reischauer-ground gears and shafts that deliver smooth, quiet, and vibration-free operation under sustained cutting pressures. The monolithic one-piece base incorporates vibration dampening technology, maintaining accuracy during high-power cutting cycles. Designed for production environments requiring maximum rigidity and extended tool life, the Power Seven-90 delivers superior surface finish and dimensional accuracy. Comprehensive safety features include full-length foot brakes and chuck guards with limit switches. This lathe represents an ideal choice for facilities machining large forgings, casings, and structural components where power, precision, and reliability are paramount requirements.
