HS v2017 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 that are numerically controlled. These grinding machines play a crucial role in the manufacturing industry, enabling the precise shaping and finishing of various metal and non-metal components. They are essential for producing high-quality parts and products across a wide spectrum of industries, from automotive and aerospace to electronics and medical equipment.

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 surface finish. The workpiece is typically held in place by a work-holding device, and the grinding wheel or belt is brought into contact with the surface, removing tiny amounts of material with each pass. The speed of the grinding wheel, the feed rate, and the depth of cut are carefully controlled to ensure the desired outcome. These machines may be equipped with various attachments and accessories to accommodate different grinding operations, such as cylindrical, surface, or tool and cutter grinding.

Production inputs

The primary inputs for the production of grinding machines under hs code 846029 include high-quality abrasive materials, such as aluminum oxide or silicon carbide, which are used to manufacture the grinding wheels or belts. Additionally, these machines require precision-engineered components, such as bearings, motors, and control systems, as well as raw materials like steel, cast iron, or aluminum for the machine's structure and housing. Skilled labor, including machinists, engineers, and technicians, is also a crucial input for the design, assembly, and maintenance of these grinding machines.

Production outputs

Grinding machines classified under hs code 846029 are used to produce a wide range of precision-engineered components and parts for various industries. These outputs may include gears, bearings, automotive parts, aerospace components, medical devices, and other precision-machined products. The outputs of this industry are often consumed by manufacturers in related sectors, such as 846021 Machine-tools; grinding machines, for working metal and 846031 (Machine-tools; sharpening (tool or cutter grinding) machines), as well as industries that require high-quality, precisely machined components.
