HS v2017 Code: 846039

About machine-tools; sharpening (tool or cutter grinding) machines, other than numerically controlled

hs code 846039 covers a range of machine-tools used for sharpening or grinding cutting tools and other industrial blades. These machines play a crucial role in maintaining the performance and longevity of a wide variety of manufacturing equipment across numerous industries. As a key component of industrial tool maintenance, the 846039 product category is an important enabler of efficient and cost-effective production processes throughout the global economy.

Production process

Machines classified under hs code 846039 typically utilize abrasive grinding wheels or discs to sharpen and refine the edges of cutting tools, blades, and other industrial implements. The workpiece is held in place while the grinding mechanism removes small amounts of material to restore the desired edge geometry and cutting performance. Some models may also incorporate additional features such as automated tool positioning, coolant systems, or specialized jigs to accommodate different tool shapes and sizes.

Production inputs

The primary inputs for the 846039 industry include the grinding wheels or abrasive discs, electric motors, and other mechanical components that make up the sharpening machine itself. High-quality steel, carbide, or other durable tool materials are also essential inputs, as the machines are tasked with maintaining the integrity of these critical industrial components. Specialized software and control systems may be required for more advanced models.

Production outputs

The primary output of the 846039 industry is sharpened and refurbished cutting tools, blades, and other industrial implements. These refurbished tools are then consumed by a wide range of manufacturing industries, including 846711 Machine-tools; for working metal, sintered metal carbides or cermets, without removing material, 846781 Machine-tools; for working metal by forging, hammering or die-stamping, and 846820 Machine-tools; for deburring, sharpening, grinding, honing, lapping, polishing or otherwise finishing metal or cermets. The ability to cost-effectively maintain and extend the useful life of these critical production assets is a key driver of efficiency and productivity across the global manufacturing sector.
