The knurling process involves pressing spare knurls against a rotating workpiece, typically a metal rod or tube. As the knurls roll over the workpiece’s surface, they create raised or indented patterns. The choice of spare knurl type, pitch, and profile determines the final pattern’s appearance and functionality.
