8459.31.00.10 - Table type, excluding planer type

This HTS classification covers numerically controlled horizontal spindle boring-milling machines, specifically those designed with a table for supporting the workpiece. These machines are utilized for operations such as boring, milling, drilling, and tapping, all while precisely removing metal. The "table type" designation is crucial, indicating that the machine's workholding surface is a table, as opposed to other configurations like floor-type or column-type machines that may fall under different subheadings.

This category is distinguished from its sibling, 8459.31.00.40 "Other," which would encompass numerically controlled boring-milling machines that do not fit the specific criteria of a horizontal spindle table-type machine. Therefore, the primary differentiator is the orientation of the spindle (horizontal) and the presence of a supporting table for the workpiece.

As this is a leaf node in the HTS structure, there are no further subcategories for this specific classification. The classification is determined by the machine's numerical control, its boring-milling function, the horizontal orientation of its spindle, and the use of a table for supporting the workpiece. Examples within this category would include CNC horizontal boring mills and CNC horizontal milling machines that feature a table for workpiece mounting and operate under numerical control.
