FIELD: metallurgy.
SUBSTANCE: invention concerns field of tool thermal treatment and can be used at manufacturing of shearing dies for notching. For endurance increasing of puncheon and matrix, hardened surface of puncheon and matrix are subjected to mechanical operation with margin implementation on its surface, then it is implemented fixing and positioning of matrix and puncheon blanks and implemented surface laser hardening with margin melting by all its high by means of ray movement by edge perimeter, oriented perpendicularly to anterior surface, at that smoothing is implemented by side surface.
EFFECT: endurance increasing of puncheon and matrix.
