HS Code for CNC centerless grinder

8460.22 Machine-tools; grinding machines (excluding flat-surface), centreless, numerically controlled
Electronics & Electrical Equipment
View full HS code details

HS code 846022 specifically covers machine-tools designed for grinding operations, characterized by their \"centreless\" design and \"numerically controlled\" (CNC) functionality. This classification is applied to machines that remove material from workpieces through abrasive processes, where the workpiece is supported by a work rest blade and regulating wheel rather than being held between centers. The \"numerically controlled\" aspect signifies that the machine's operations, such as feed rates, grinding wheel speeds, and workpiece dimensions, are precisely controlled by a computer program, enabling high precision, repeatability, and automation. This code precisely distinguishes these sophisticated machines from conventional or non-CNC grinding machines, as well as from other types of grinding machines that utilize different workpiece holding methods or are designed for different surface geometries, ensuring accurate international trade classification.

Common Misclassification

A common misclassification occurs with HS 846023, which covers \"Machine-tools; cylindrical grinding machines (excluding flat-surface and centreless), numerically controlled.\" The fundamental distinction lies in the workpiece support method: 846022 is specifically for centreless grinding, where the workpiece is not held between centers, whereas 846023 applies to cylindrical grinders that typically hold the workpiece between centers. Another potential area of confusion is with HS 846024, a residual category for \"other\" numerically controlled grinding machines. However, 846022 is a more specific and appropriate classification for dedicated centreless grinders, and should be prioritized when the machine's characteristics align with this description.

FAQ

What is the HS code for CNC centerless grinder?

The HS code for a CNC centerless grinder is 846022. This code specifically identifies numerically controlled machine-tools for centreless grinding operations, ensuring precise customs classification.

What is the primary advantage of a centerless grinding process?

The primary advantage of centerless grinding is its high production rate, suitability for processing long, slender workpieces or large batches of smaller parts, and the elimination of the need for center holes. This method offers exceptional concentricity, superior surface finish, and reduced setup times, making it highly efficient for mass production of precision components.
