Question

Quizplus · Accepted Answer

Technician A is correct since knurling entails a metal displacement process in which a knurling wheel pressurizes the material, forming small ridges that improve grip. Technician B's statement regarding guides worn as much as 0.012" being successfully knurled might not be accurate since it depends on the material's hardness and existing knurl depth, among other factors.
