AMERICAN TURNMASTER THL-1550 MANUAL LATHE

Technical Description

The American Turnmaster THL-1550 is a robust manual lathe designed for precision machining and heavy-duty turning applications. Featuring a 15-inch swing over the bed and a 9.45-inch swing over the cross slide, this lathe provides ample clearance for a wide range of workpieces. With a distance between centers of 50 inches, it accommodates long parts and shafts, making it ideal for both toolroom and production environments. The lathe is equipped with a 2.17-inch spindle bore, allowing for the passage of large-diameter bar stock, and a D1-6 spindle nose for secure chuck mounting. Powered by a 7.5 HP motor, the THL-1550 delivers consistent performance and torque, supporting a maximum spindle speed of 2,000 RPM for efficient high-speed turning. The geared headstock ensures reliable power transmission and smooth operation across all speed ranges. Hardened and ground bed ways, along with turcite-covered carriage ways, enhance durability and reduce friction for precise movement and extended machine life. The lathe includes a full-length rear splash guard, overload feed clutch, and constant horsepower design, ensuring operator safety and protection against mechanical stress. Standard equipment features a foot brake, disc clutch, thread dial, and a 4-way tool post, while optional accessories such as various chucks, taper turning attachments, and steady rests can be added for increased versatility. The THL-1550’s gap bed design allows for the turning of larger diameters, and its overall construction emphasizes rigidity, accuracy, and ease of maintenance.
