Which code does this activity belong in?
Machine shops perform custom machining of metal and plastic parts on a job or order basis using machine tools like lathes, automatic screw machines, and grinding or milling equipment. The distinction from turned product and fastener manufacturing lies in the nature of the work: machine shops handle low-volume custom machining jobs across diverse applications, while turned product and fastener manufacturers focus on precision turned products or the production of standardized industrial fasteners such as bolts, nuts, and screws, whether custom or not.
