A method for verifying the integrity of a tool in automatic multi-tool key duplicating machines, characterised by bringing each tool (8, 8'), mounted on the relative tool holder, into contact at predetermined frequency with a reference plug (14) applied to a fixed point of said machine, then determining, by means of an electrical signal generated by the contact of the tip of said tool with said reference plug, the position of the tip of said tool (8, 8') relative to said reference plug (14), monitoring the variation of this position with time, and considering the tool no longer integral if a predetermined value of said position variation is exceeded. |
