8458.11.00.10 - Multiple spindle

This HTS category, 8458.11.00.10, specifically classifies numerically controlled horizontal lathes that are designed with multiple spindles. These machines are sophisticated metalworking tools capable of performing turning operations on workpieces using multiple spindles simultaneously or sequentially, enhancing efficiency and production capacity. The "multiple spindle" designation is the key differentiator, indicating a design that allows for concurrent machining on several parts or complex multi-axis operations on a single part through the use of multiple rotating tool-holding or workpiece-holding spindles.

The primary distinction for this subcategory lies in its configuration of multiple spindles. While other numerically controlled horizontal lathes within the 8458.11.00 group may feature single spindles, this classification is reserved for those equipped with two or more spindles. This multi-spindle capability is integral to the machine's function, enabling operations such as simultaneous turning, parting-off, and secondary operations without requiring manual intervention or re-fixturing of the workpiece between distinct stages.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus for classification under 8458.11.00.10 is on the definitive presence of a multi-spindle configuration in a numerically controlled horizontal lathe intended for metal removal. Importers and exporters should confirm that the subject machinery is equipped with and designed to operate with multiple spindles to ensure correct classification.
