OLYMPIC LATHE #4 MANUAL LATHE

Technical Description

The Olympic Lathe #4 is a conventional manual engine lathe designed for general-purpose turning operations in small to mid-sized machine shops. This geared-head lathe features an 18.8-inch swing over the bed, providing adequate capacity for moderate workpiece diameters, while maintaining a compact footprint suitable for space-constrained facilities. The 74.7-inch distance between centers accommodates longer workpieces, enabling extended turning and threading applications. The spindle bore of 2.0 inches accepts standard tooling and workholding devices, facilitating versatile clamping options for various part geometries. Powered by a 3.0 HP motor, the lathe delivers consistent cutting force across its operational speed range, typical of manual lathes in this class. The 11.0-inch swing over the cross slide indicates adequate clearance for tool movement during facing and turning operations on the workpiece. Construction follows conventional lathe design principles, incorporating induction-hardened and precision-ground ways for dimensional accuracy and repeatability. The lathe typically features a Norton-style universal gearbox providing multiple spindle speeds for both inch and metric threading, along with various feeds for turning operations. Manual operation allows experienced machinists full control over cutting parameters and tool engagement. This machine is well-suited for prototype work, small production runs, and maintenance operations requiring reliable, straightforward turning capability without the complexity of CNC systems.
