HS v2022 Code: 846029

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

HS code 846029 covers a range of machine-tools used for grinding operations, excluding those designed for flat-surface grinding. These grinding machines are essential components in various manufacturing industries, enabling the precise shaping and finishing of complex components. They play a crucial role in the production of high-quality parts and products, contributing to the overall efficiency and competitiveness of the global economy.

Production process

Grinding machines classified under HS code 846029 utilize abrasive wheels or belts to remove material from the workpiece, achieving a smooth and precise finish. The workpiece is typically held in place by a chuck or fixture, and the grinding wheel or belt is moved across the surface to grind away excess material. Advanced models may feature automated controls and programmable movements to ensure consistent and repeatable results.

Production inputs

The primary inputs for the production of grinding machines under HS code 846029 include high-quality steel for the machine frame and components, as well as specialized abrasive materials for the grinding wheels or belts. Additionally, these machines require precision bearings, motors, and control systems to ensure smooth and accurate operation. Manufacturers may also rely on specialized software and programming tools to design and configure the machines for specific applications.

Production outputs

Grinding machines classified under HS code 846029 are used to produce a wide range of precision components and parts for various industries, including 846711 machinery, 848310 transmission shafts, cranks, and crankshafts, and 848340 gears and gearing. The output of these machines is often consumed by manufacturers in the 871200 bicycle, 842199 machinery for the treatment of materials by a process involving a change in temperature, and 848320 ball or roller bearings industries, among others.
