HS v2022 Code: 845931

About machine-tools; for boring-milling by removing metal, numerically controlled

HS code 845931 covers machine-tools used for boring and milling operations that remove metal, with numerical control. These specialized machine-tools are essential for precision manufacturing across a wide range of industries, including automotive, aerospace, and general engineering. They play a crucial role in the production of complex metal components, enabling high-accuracy machining and efficient material removal processes.

Production process

Machine-tools under HS code 845931 utilize computer numerical control (CNC) technology to automate the boring and milling operations. These machines are programmed to precisely control the movement of the cutting tool, allowing for intricate and repeatable machining of workpieces. The key production techniques involve clamping the workpiece, selecting the appropriate cutting tools, and executing the pre-programmed machining sequence to achieve the desired part geometry and surface finish.

Production inputs

The primary inputs for the production of machine-tools under HS code 845931 include high-quality metal alloys, such as steel and aluminum, for the construction of the machine components. Specialized cutting tools, including drill bits, end mills, and boring bars, are also essential inputs. Additionally, these machine-tools require advanced control systems, including computer hardware and software, to enable the numerical control functionality.

Production outputs

Machine-tools classified under HS code 845931 are used to produce a wide range of precision-machined metal components, which are then consumed by various downstream industries. These outputs may include engine parts, aerospace components, medical devices, and other complex metal products. The outputs of this industry are often used as inputs for 848410 Taps, cocks, valves and similar appliances, 848620 Machines and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits and 848690 Parts and accessories for the machines and apparatus of heading 8486.
