8459.59.00 - Other

This classification pertains to milling machines that are not numerically controlled, specifically those of the knee-type design. These machines are utilized for metal removal operations such as milling, drilling, boring, tapping, and threading. The defining characteristic of this category is the absence of automated numerical control for their operations.

Distinguishing this category from its sibling, 8459.51.00, is crucial. Heading 8459.51.00 exclusively covers numerically controlled knee-type milling machines, which employ computer programming for precise control of machining operations. Therefore, machines classified under 8459.59.00 are operated manually or through simpler mechanical controls, lacking the advanced digital programming capabilities found in their numerically controlled counterparts.

Within this classification, further subdivisions are provided to refine the classification based on specific attributes. The subcategories differentiate based on whether the milling machine is used or rebuilt, offering a distinct classification for pre-owned equipment. Additionally, further distinctions are made based on the value of the machine, allowing for granular classification of new machines that do not meet the criteria for numerically controlled units.
