2011 Hankook Protec-9NC CNC Oil Country Lathe

The Hankook Protec-9NC is a flat bed CNC oil country lathe built for heavy-duty turning of large-diameter, long workpieces — the kind of machine that earns its place in pipe shops, energy service companies, and heavy fabrication environments. This 2011 unit features a 37.4-inch swing over bed, a maximum turning length of 157 inches, and a 9.75-inch spindle bore sized for oil country pipe work. X-axis travel measures 16 inches with Z-axis travel at 151 inches. The spindle delivers speeds from 1 to 630 RPM, and the machine is equipped with dual 24-inch 4-jaw chucks with 9.75-inch through-holes, a 4-side auto tool turret, three steady rests, and a Fanuc Series 21i-TB CNC control.

The Protec-9NC represented a meaningful step forward from Hankook's earlier Protec-7N and Protec-9N models, which shared a similar heavy-duty flat bed architecture but lacked the updated CNC integration and refined servo systems of the 9NC. The Protec-9NC introduced improved axis positioning accuracy, a more capable Fanuc control platform over the older 18i-T series used on predecessor models, and better rapid traverse rates — all of which translate to tighter tolerances and faster cycle times on long turning operations. For a shop looking to step up from an aging oil country lathe without paying new-machine prices, this 2011 Protec-9NC delivers the production capability of a much newer machine at a used-equipment value.
