B24 GRINDING; POLISHING
Description
B24 encompasses machines, tools, and processes for grinding and polishing solid materials through abrasive action. This class covers grinding wheels, abrasive belts, honing stones, lapping equipment, and the mechanical apparatus that drives these operations across industrial and precision applications. It includes both the design of abrasive implements and the machines that control feed rate, speed, and contact pressure to achieve desired surface finishes or dimensional tolerances. Related finishing operations such as superfinishing and related abrasive processes fall within this classification.
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
