KINGSTON HR-4080 MANUAL LATHE

Technical Description

The Kingston HR-4080 is a heavy-duty manual engine lathe engineered for versatile machining operations in job shops, production facilities, and tool rooms. This workhorse machine features a 40-inch swing capacity over the bed, enabling the processing of substantial workpieces. With an 80-inch center-to-center distance, the lathe accommodates extended bar stock and shaft work, making it ideal for medium to large-scale turning operations. The spindle bore measures 4.09 inches, providing adequate clearance for various workholding configurations and through-spindle operations. Powered by a robust 20 horsepower motor, the HR-4080 delivers consistent cutting performance with a maximum spindle speed of 800 RPM, optimizing efficiency for heavy turning and threading tasks. The cross slide swing of 31 inches allows for significant tool movement and clearance during machining. The hardened and ground bedway ensures dimensional accuracy and repeatability across production runs, while the precision-ground spindle features multi-point bearing support for minimal runout and reliable performance. The machine is equipped with a comprehensive feed and speed range to accommodate both inch and metric threads without extensive change gear adjustments. The timing-belt-driven gearbox provides smooth, quiet operation while enabling rapid speed changes. Manual operation affords operators direct control over cutting parameters and the ability to respond to machining conditions in real-time. The HR-4080's combination of sturdy construction, adequate power, and practical capacity makes it suitable for general machining, custom fabrication, thread chasing, and repair work, delivering years of reliable service in demanding shop environments.
