FIELD: machine engineering, possibly manufacture of flat threading dies used for forming outer thread by plastic deformation.
SUBSTANCE: apparatus includes knurling tool with thread on cylindrical surface. Outer diameter of knurling tool exceeds by n times diameter of thread to be knurled by means of threading dies. Thread of knurling tool has n starts where n - natural number. Profile of knurling tool thread in axial section completely corresponds to profile of thread formed by means of threading dies.
EFFECT: increased useful life period, enhanced wear resistance of knurling tool.
