HS Code for CNC cylindrical grinder

HS code 846023 is designated for machine-tools that perform cylindrical grinding operations and are \"numerically controlled\" (CNC). This classification specifically targets machines designed to remove material from the external or internal surfaces of cylindrical workpieces, where the workpiece is typically held between centers or in a chuck. The \"numerically controlled\" aspect signifies that the machine's movements, grinding parameters, and operational sequences are precisely managed by a computer program, ensuring high accuracy, repeatability, and automated production capabilities. The description explicitly excludes flat-surface and centreless grinding machines, thereby narrowing the scope to conventional cylindrical grinding applications. This precise definition aids in differentiating these advanced machines from other grinding technologies and non-CNC variants.

Common Misclassification

A frequent misclassification involves HS 846022, which covers \"Machine-tools; grinding machines (excluding flat-surface), centreless, numerically controlled.\" The key distinction lies in the workpiece holding method: 846023 is for cylindrical grinders that typically use centers or chucks, while 846022 is for centreless grinders where the workpiece is supported differently. Another potential area of confusion is with HS 846024, a residual category for \"other\" numerically controlled grinding machines. However, 846023 is a more specific and appropriate classification for dedicated cylindrical grinders that are not centreless or flat-surface types.

FAQ

What is the HS code for CNC cylindrical grinder?

The HS code for a CNC cylindrical grinder is 846023. This code specifically covers numerically controlled machine-tools designed for cylindrical grinding operations, excluding flat-surface and centreless types.

How does a cylindrical grinder differ from a surface grinder?

A cylindrical grinder is designed to process the external or internal surfaces of cylindrical workpieces, typically rotating the workpiece on its axis. In contrast, a surface grinder is used to produce flat, smooth surfaces on workpieces, usually by traversing the workpiece under a rotating grinding wheel. Their applications and operational principles are distinct.
