Technical Description

The SUMMIT BIG SWING 42X60 is a precision manual engine lathe designed for general-purpose turning operations on medium to large workpieces. Featuring a 42-inch swing over the bed and 19.3-inch swing over the cross slide, this machine accommodates substantial components while maintaining accuracy. The 60-inch center distance allows for extended workpiece lengths, with optional configurations extending to 240 inches for specialized applications. The lathe incorporates a forged, chrome alloy spindle with a 6.1-inch thru-hole bore, mounted in three precision bearings to ensure dynamic balance and stability during operation. The machine is constructed with a fully ribbed, closed-grain cast iron bed measuring 27.5 inches wide, providing exceptional rigidity and vibration damping. Bedways are induction-hardened and precision-ground to maintain accuracy over extended service life. Standard features include a quick-change gearbox capable of cutting American inch, metric, and module threads, enabling versatile threading operations. A 4-way joystick controls rapid traverse on the carriage for efficient workpiece positioning. The clutched headstock, available in both stepped-speed and variable-speed configurations, delivers controlled power transmission. Included accessories enhance operational capability and safety, encompassing thread dial, steady rest, follow rest, coolant system, taper attachment, work light, full-length splash guard, and both 3 and 4-jaw chucks. These features combine to establish the BIG SWING 42X60 as a comprehensive solution for precision turning work in tool rooms, job shops, and manufacturing environments.
