Machine-tools; flat-surface grinding machines, other than numerically controlled

HS v2017 Code: 846019

About machine-tools; flat-surface grinding machines, other than numerically controlled

hs code 846019 covers a range of machine tools used for flat surface grinding, excluding those that are numerically controlled. These machines play a crucial role in the manufacturing industry, enabling the precise shaping and finishing of various metal and non-metal components. They are widely used across sectors such as automotive, aerospace, and general engineering, contributing to the production of high-quality, durable parts and products.

Production process

Flat-surface grinding machines operate by rotating an abrasive grinding wheel against the surface of the workpiece, removing material in a controlled and precise manner. The workpiece is typically held in place by a magnetic or mechanical chuck, and the grinding wheel is guided across the surface using a combination of manual and automated controls. The depth of cut, wheel speed, and feed rate are carefully adjusted to achieve the desired finish and dimensional accuracy.

Production inputs

The key inputs for the production of flat-surface grinding machines include high-quality steel or other durable materials for the machine frame and components, precision-engineered bearings and spindles, and advanced control systems. Additionally, abrasive grinding wheels, coolants, and lubricants are essential consumables required for the grinding process.

Production outputs

The primary output of hs code 846019 is flat-surface grinding machines, which are then utilized by a wide range of manufacturing industries. These machines are often used in the production of 846021 Grinding machines, other than gear cutting, gear grinding or gear finishing machines, for working metals, sintered metal carbides or cermets, 846029 Machine-tools for deburring, sharpening, grinding, honing, lapping, polishing or otherwise finishing metal, sintered metal carbides or cermets, and 848050 Metal-rolling mills and rolls therefor.
