HS v2017 Code: 845620

About machine-tools; for working any material by removal of material, operated by ultrasonic processes

hs code 845620 covers a specialized category of machine tools used for working materials through the removal of material using ultrasonic processes. These advanced machine tools play a crucial role in various manufacturing industries, enabling precision shaping and finishing of components with exceptional accuracy and efficiency. As a key part of the broader metalworking and industrial machinery sector, this industry contributes significantly to the global economy by supporting the production of a wide range of durable goods and high-value industrial products.

Production process

The primary production technique for machine tools under hs code 845620 is ultrasonic machining. This process utilizes high-frequency vibrations, typically in the range of 20-40 kHz, to remove material from the workpiece. The vibrating tool, coupled with an abrasive slurry, creates a controlled erosion effect that allows for the precise shaping and finishing of even the hardest of materials, including ceramics, glass, and advanced composites. The ultrasonic action, combined with computer numerical control (CNC) technology, enables these machine tools to achieve intricate geometries and tight tolerances that are essential for many industrial applications.

Production inputs

The main inputs required for the production of machine tools under hs code 845620 include specialized metalworking components, such as high-precision spindles, linear guides, and control systems. Additionally, these machine tools require a reliable supply of electrical power, cooling systems, and abrasive slurries or cutting fluids to facilitate the ultrasonic machining process. Skilled technicians and engineers are also a critical input, as the design, programming, and maintenance of these advanced machine tools require specialized knowledge and expertise.

Production outputs

Machine tools classified under hs code 845620 are primarily used for the production of precision components and parts across a wide range of industries, including aerospace, automotive, electronics, and medical device manufacturing. The outputs of this industry can be found in 848410 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves, 848620 Machinery parts, not containing electrical connectors, insulators, coils, contacts or other electrical features, and 902190 Instruments and appliances used in medical, surgical or veterinary sciences, n.e.c. in heading no. 9021, among others.
