WILLIS SK26120 MANUAL LATHE

Technical Description

The Willis SK26120 is a heavy-duty manual geared head engine lathe designed for precision metalworking. It features a substantial 26-inch swing over the bed and a 17-inch swing over the cross slide, allowing it to handle large diameter workpieces. The lathe offers a generous 120-inch distance between centers, making it suitable for long shafts and large components. The spindle bore measures 4.1 inches, accommodating substantial bar stock through the headstock. Powered by a robust 15-horsepower motor, the lathe achieves spindle speeds up to 1,200 RPM, providing versatility for various cutting operations. Its bed is constructed with large, widely spaced ways and a large diameter lead screw for enhanced rigidity and reduced vibration, ensuring high precision. The spindle assembly includes a camlock spindle nose (A2-8) and a taper for M.T. #5 centers. Longitudinal and cross feeds are finely adjustable, with feed rates ranging from 0.0002" to 0.016" per revolution, and metric and inch threading capabilities are integrated, supporting a wide range of threads (inch: 2-28 TPI; metric: 0.8-14 mm). The machine is equipped with safety features including a manual foot brake and adjustable feed overload clutch. Additional features typically include a Newall DP700 2-axis DRO, a four-jaw chuck, flood coolant system, and lighting, enhancing operational convenience. The lathe’s robust construction and precision components make it ideal for demanding applications such as oil field work, shipbuilding, roller manufacturing, and hydraulic cylinder machining.
