Technical Description

The SUMMIT 20 - 4 x 60A Manual Lathe features a 20-inch swing capacity and 60-inch distance between centers, making it suitable for medium to large workpieces. It is equipped with a robust 10 HP motor driving the spindle at speeds up to 1,500 RPM. The spindle bore is 4 inches in diameter, allowing for the passage of sizable bar stock. It offers a 13.25-inch swing over the cross slide for versatile machining operations. The machine is constructed on a heavy, fully ribbed, close-grain cast bed for enhanced stability and minimal thermal distortion. The lathe incorporates a cross-ribbed headstock with anti-friction mounted shafts and hardened, ground alloy steel gears to ensure precision and long service life. The spindle is oversized, made from precision chrome alloy, mounted on opposing tapered roller thrust bearings plus double-row roller bearings, providing high radial and thrust capacity for accurate turning. Safety interlocks prevent simultaneous engagement of feed and threading motions, enhancing operator safety. The lathe includes a quick-change gearbox capable of cutting standard American, Metric, and Module threads, as well as essential accessories like steady and follow rests, taper attachment, coolant system, halogen work lamp, 12-inch 3-jaw chuck with two-piece jaws, and a 4-jaw chuck. Dimensions measure approximately 114" length by 44" width by 64" height, and it weighs 5,590 lbs, reflecting its rugged build and stability. This lathe is designed for precision, durability, and ease of operation in demanding metalworking environments.
