Metalworking Machinery and Equipment Manufacturing

Establishments primarily engaged in manufacturing metal cutting machine tools that are not handheld and are used to shape metal through cutting or electrical techniques, as well as rebuilding such machine tools and manufacturing replacement parts for them. This industry also includes metalworking machine tools designed primarily for home workshops. Sample business functions include automatic chucking machines, metalworking boring machine tools, boring mills, boring, drilling, and milling machine combinations, broaching machines, brushing machines for metalworking, buffing and polishing machines, burnishing machines, centering machines, and chemical milling machines.

Establishments primarily engaged in manufacturing cutting tools, machinists' precision measuring tools, and attachments and accessories for machine tools and other metalworking machinery not elsewhere classified. Sample business functions include angle rings, arbors for machine tools, bits for use on lathes, planers, and shapers, cutting tool blanks, boring machine attachments, broaches, calipers and dividers, cams, chasers, and drill, lathe, and magnetic chucks.

Establishments primarily engaged in manufacturing electric and gas welding and soldering equipment and accessories. Also included are establishments engaged in coating welding wire from purchased wire or wire drawn within the same facility. Sample business functions include arc-welder transformers, transformer-rectifier arc-welders, AC and DC arc-welding generators, electrode holders for electric welding apparatus, electric welding electrodes, gas welding equipment, separate generators for arc-welders, electric resistance welders, welding, soldering, or brazing robots, and gas and electric seam welding apparatus.
