HS v2022 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 tools and cutters, excluding those that are numerically controlled. These machines play a crucial role in the manufacturing industry, ensuring the precision and longevity of cutting tools used in various production processes. As a key component of the broader metalworking machinery sector, this industry supports a wide range of downstream industries, from automotive and aerospace to construction and consumer goods manufacturing.

Production process

Machine-tools classified under HS code 846039 typically utilize abrasive wheels or discs to sharpen and grind the cutting edges of tools and cutters. The process often involves securing the tool or cutter in a specialized holding device, then bringing it into contact with the rotating abrasive surface to remove material and restore the desired edge geometry. Precision adjustments and monitoring are essential to ensure consistent results and avoid damage to the tools being processed.

Production inputs

The main inputs for this industry include the machine-tools themselves, which are typically composed of a sturdy frame, drive mechanisms, and specialized tool-holding and adjustment systems. Additionally, the abrasive wheels or discs used for the grinding and sharpening process are a critical input, with different abrasive materials and grit sizes selected based on the specific application. Electricity to power the machines and skilled operators to set up and monitor the process are also essential inputs for this industry.

Production outputs

The primary output of HS code 846039 is sharpened or ground tools and cutters, which are then consumed by a wide range of downstream industries. These sharpened tools may be used in 846029 Machine-tools; grinding, polishing or lapping machines, for working metal, 846040 Machine-tools; honing or lapping machines, for working metal, or other metalworking processes. The improved performance and extended lifespan of these tools can contribute to increased efficiency and productivity in various manufacturing sectors.
