The Sherline 17" Ball Screw Benchtop Lathe #1 Morse Headstock High-Torque Stepper Motors is an advanced iteration of the renowned 17-inch, 4400-series benchtop lathe. This model features a robust solid aluminum base, enhancing the rigidity of the assembly. The lathe is equipped with an upgraded saddle designed to support ball screws, and it includes a larger crosslide measuring 8 inches. The integration of #23 NEMA frame stepper-motor mounts with high-torque couplings further enhances its performance capabilities.

This lathe offers a swing over bed of 5.97 inches and a swing over carriage of 1.75 inches, providing ample space for various machining tasks. The distance between centers is 17 inches, allowing for the accommodation of longer workpieces. The spindle features a hole through diameter of .405 inches and a spindle nose thread of 3/4-inch-16 T.P.I., with a #1 Morse taper. The spindle runout is impressively low, at .0005 inches or less, ensuring precision in operations.

The crosslide travel is 4.6 inches, while the Z-axis travel extends to 14.45 inches, offering substantial movement for intricate machining processes. The tailstock spindle is tapered to #0 Morse, and the protractor provides graduations from 0° to 45° in 5° increments. The handwheel is graduated in .02 mm increments, facilitating precise adjustments.

The lathe is powered by a 90-volt DC motor with an electronic speed controller, allowing for a spindle speed range of 70 to 2800 RPM, which is continuously variable. The standard headstock is equipped with a #1 Morse taper and a 3/4 x 16 external spindle thread. The base is constructed from a 28-inch by 5-inch by 1/2-inch solid 6061 aluminum plate, ensuring durability and stability. The lathe saddle is hard anodized to provide long-lasting wear resistance.

The steel bed measures 24 inches, with 17 inches between centers, and the leadscrew is operated by a 2.5-inch resettable "zero" handwheel. The lathe includes a 3/8-inch insert holder tool post with a 55° right-hand tool holder featuring a carbide insert. Additional components include pulleys, a drive belt, a faceplate, a lathe dog, two dead centers, three hexagonal keys, an eight-foot three-wire power cord, and an instruction manual.
