B23 MACHINE TOOLS; METAL-WORKING NOT OTHERWISE PROVIDED FOR
Description
B23 encompasses machine tools and metal-working processes that are not classified elsewhere in the IPC system. This class covers a broad range of equipment and methods for shaping, cutting, forming, and finishing metal workpieces, including lathes, milling machines, grinding equipment, and specialized metal-removal or metal-forming devices. The classification includes both the machines themselves and the operational techniques employed in metal-working, as well as auxiliary systems and components integral to these processes. Adjacent classes address more specialized metal-working technologies (such as B21 for metal rolling or forging) and non-metal material processing, making B23 the residual classification for conventional machine-tool technology not specifically assigned elsewhere.
