SUMMIT 16-3 MANUAL LATHE

Technical Description

The Summit 16-3 Manual Lathe is a heavy-duty precision engine lathe engineered for mid-size production environments requiring accuracy and strength. Featuring an 16-inch swing over bed with 40 inches between centers, this lathe accommodates workpieces up to 18 inches in diameter over the bed and 9.5 inches over the cross slide. The robust 3-inch spindle bore enables flexible workpiece handling with a thru hole capacity suitable for larger components. Powered by a 10 HP motor with spindle speeds ranging from 20 to 2,000 RPM across 21 preset speeds, the machine delivers consistent performance across diverse machining applications. All-cast iron construction with hardened and precision-ground bedways provides exceptional rigidity and vibration absorption for superior surface finishes. The lathe incorporates a clutched headstock with dynamically balanced shafts mounted in high-accuracy antifriction bearings, ensuring long-lasting reliability and precise control. A quick-change gearbox enables rapid threading in American (inch), metric, and module formats with 64 thread options ranging from 0.25 to 60 TPI. The innovative four-way joystick rapid traverse allows unrestricted carriage and cross-slide movement for efficient setup. Measuring 114" x 48" x 60" and weighing approximately 6,200 pounds, the Summit 16-3 combines industrial-grade construction with operator-friendly controls, making it one of the easiest precision lathes to operate in its class while delivering pinpoint accuracy for demanding machining tasks.
