HS v2022 Code: 846019

About machine-tools; flat-surface grinding machines, other than numerically controlled

HS code 846019 covers a range of machine tools used for flat-surface grinding, excluding those that are numerically controlled. These machines play a crucial role in the manufacturing industry, enabling the precise shaping and finishing of various metal and non-metal components. They are widely used across sectors such as automotive, aerospace, and general engineering, contributing to the production of high-quality, durable products that are essential for the broader economy.

Production process

Flat-surface grinding machines operate by using a rotating abrasive wheel to remove material from the surface of a workpiece, achieving a smooth, flat finish. The workpiece is typically held in place by a magnetic or mechanical chuck, and the grinding wheel is precisely controlled to ensure consistent and accurate results. These machines may employ a variety of grinding wheel materials and configurations, depending on the specific requirements of the application.

Production inputs

The key inputs for the production of flat-surface grinding machines include high-quality steel and other metal alloys for the machine components, as well as specialized abrasive materials for the grinding wheels. Additionally, these machines require advanced control systems, motors, and other electronic components to ensure precise operation. Manufacturers in this industry also rely on a skilled workforce capable of designing, assembling, and maintaining these specialized machine tools.

Production outputs

The primary output of HS code 846019 is flat-surface grinding machines, which are then consumed by a wide range of manufacturing industries. These machines are used to produce high-precision components for 870000 Motor vehicles, trailers and semi-trailers, 880000 Aircraft, spacecraft, and parts thereof, 850000 Electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles, and various other sectors that require tight tolerances and smooth finishes.
