An automatic tool changing device includes a frusto-conically shaped tool holder holding a large number of machining tools and mounted on the forward end of the head of a machining center so as to be vertically movable and rotatable about a non-rotating shaft which is slanted downwardly, whereby by rotating the tool holder, the desired tool can be automatically and sequentially attached to the cutter head spindle of the machining center, used to machine a work and then removed so that the next tool can be attached to the cutter head spindle. |
