AMERICAN TURNMASTER POWER SEVEN-70 MANUAL LATHE

Technical Description

The American Turnmaster Power Seven-70 is a heavy-duty manual engine lathe engineered for demanding industrial turning applications. This machine features a substantial 69.96-inch swing capacity with a 9.05-inch spindle bore, accommodating large workpieces for extended production runs. The robust 50.2 HP motor delivers sufficient torque for aggressive cutting operations, operating at a maximum of 600 RPM to maintain control during heavy-duty machining. The Power Seven series incorporates a massive one-piece floor-type bed with superior Meehanite G-50 castings, eliminating pedestals for maximum rigidity and vibration absorption. This rigid foundation is essential for maintaining dimensional accuracy during sustained cutting cycles. The machine's 52.94-inch swing over the cross-slide accommodates wider workpieces while maintaining precision. The design includes a four-shear bed with dual way center guides and front lateral way for carriage support under heavy loading conditions. Standard features include a powerful tailstock with built-in rotary live center, hydraulic-controlled body movement on bedways, and quill travel for consistent positioning. Automatic lubrication throughout the machine ensures extended component life and reliable operation. The lathe provides 18 spindle speeds and supports both inch and metric threading capabilities, making it versatile for diverse machining requirements. This configuration is particularly suited for oil and gas applications, heavy manufacturing, and production environments requiring consistent performance with large-diameter workpieces.
