Slotting tool for machining key groove

摘要: The utility model discloses a slotting tool for machining key groove. the groove comprises handle and rod, wherein is arranged on chuck of shaft numerically-controlled machine tool, particularly, long strip-shaped hard alloy blade fixedly plurality teeth are at intervals in axial direction rod ground mode, heights become larger gradually from end to handle. According used cutting, compared with traditional single tooth has advantages being service life high efficiency; gradually, this way, cutting improving capacity, precision production efficiency can be improved; each toot provided main edge an auxiliary edge, thus reliability edges ridges polished multiple times, durability detachable, which suitable selected assembled according requirements, application range widened, operation convenient rapid.
