Machine-tools; cylindrical grinding machines (excluding flat-surface and centreless), numerically controlled

HS v2022 Code: 846023

About machine-tools; cylindrical grinding machines (excluding flat-surface and centreless), numerically controlled

HS code 846023 covers numerically controlled cylindrical grinding machines, which are essential tools in the manufacturing industry. These specialized machine-tools play a crucial role in the precision grinding and finishing of cylindrical workpieces, enabling the production of high-quality components for a wide range of applications, from automotive and aerospace to industrial machinery and consumer goods.

Production process

Cylindrical grinding machines utilize abrasive wheels to remove material from the surface of rotating cylindrical workpieces, achieving a high degree of dimensional accuracy and surface finish. The numerical control (NC) feature allows for automated, computer-guided operation, enabling precise control over the grinding process parameters, such as feed rate, depth of cut, and spindle speed. This advanced technology ensures consistent quality and productivity, making these machines indispensable in modern manufacturing environments.

Production inputs

The production of HS code 846023 cylindrical grinding machines requires a range of inputs, including specialized grinding wheels, high-precision bearings, advanced control systems, and robust machine frames. Additionally, these machines rely on a skilled workforce capable of operating and maintaining the equipment, as well as designing and programming the necessary control software.

Production outputs

Cylindrical grinding machines produced under HS code 846023 are primarily used to manufacture precision components for a variety of industries. Their output is often consumed by manufacturers of 840120 Engines and motors, non-electric for crankshaft and camshaft grinding, 848210 Ball or roller bearings for bearing race production, and 848320 Machinery parts; parts of machinery of heading 8483, not containing electrical connectors, insulators, coils, contacts or other electrical features for the finishing of other mechanical components.
