Used CNC Boring Mills
Used horizontal boring mills for large-part machining.
CNC horizontal boring mills handle large, heavy workpieces requiring precise hole placement and contouring across multiple faces. Common in heavy fabrication, oil & gas, power generation, and aerospace structural work — anywhere parts are too big or too heavy for a standard machining center.
CNC South stocks inspected used CNC boring mills from the manufacturers buyers trust most: Toshiba, Giddings & Lewis, Doosan, Kuraki, Union, and Lucas. Inventory includes table-type and floor-type boring mills with spindle diameters from 4" through 8"+ and table capacities to handle multi-ton workpieces.
When evaluating a used boring mill, key considerations include spindle diameter, X/Y/Z travels, table size and load capacity, ram/quill stroke, and control type. Every boring mill in our inventory is mechanically inspected, with spindle alignment, way condition, and control health verified before listing.
