MAKING GEARS OR TOOTHED RACKS (by stamping B21D; by rolling B21H; by forging or pressing B21K; by casting B22; arrangements for copying or controlling B23Q; machines or devices for grinding or polishing, in general B24B)

Description

B23F covers machine tools, processes, and equipment specifically designed for manufacturing gears and toothed racks through cutting, shaping, or finishing operations. This includes gear hobbing machines, gear shaping machines, gear grinding equipment, and related tools for producing spur gears, helical gears, bevel gears, and rack teeth. The classification encompasses both the machines themselves and the manufacturing methods employed, such as hobbing, shaping, grinding, and lapping of gear teeth.
