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

HS code 846031 covers numerically controlled machine-tools used for sharpening or grinding tools and cutters. This industry plays a crucial role in maintaining and optimizing the performance of various manufacturing and production equipment across diverse sectors. Efficient tool sharpening is essential for ensuring consistent product quality, reducing waste, and maximizing the lifespan of expensive machinery.

Production process

Numerically controlled sharpening machines utilize advanced computer-controlled systems to precisely grind and sharpen tools and cutters. These machines can be programmed to perform complex sharpening operations with a high degree of accuracy and repeatability. The process typically involves securely mounting the tool or cutter, selecting the appropriate grinding wheel or abrasive, and executing a pre-programmed sharpening routine controlled by the machine's numerical control system.

Production inputs

The main inputs for this industry include the tools and cutters requiring sharpening, such as drill bits, milling cutters, lathe tools, and other specialized cutting implements. Additionally, these machines require high-quality abrasive grinding wheels, coolants, and lubricants to ensure efficient and effective sharpening. Specialized software and control systems are also essential for the numerical control functionality of these machine-tools.

Production outputs

The primary output of this industry is sharpened and optimized tools and cutters, which are then consumed by a wide range of manufacturing and production industries. The sharpened tools and cutters are used in the production of goods across various sectors, including 842231 Machinery; for working metal, sintered metal carbides or cermets, without removing material, 846711 Tools; hand-operated, pneumatic, hydraulic or with self-contained electric or non-electric motor, and 846781 Tools; for working in the hand, pneumatic, hydraulic or with self-contained electric or non-electric motor, n.e.c. in heading no. 8467.
