Slot cutter for machining key slot

摘要: The invention discloses a slot cutter for machining key slot. comprises handle and inserting rod, wherein the is clamped on shaft chuck of numerically-controlled machine tool; particularly, rod fixedly provided with long-strip-shaped hard alloy blade plurality teeth are arranged at intervals along axial direction in grinding way; heights from end part to gradually increased. By applying cutter, used cutting; compared traditional single cutting tooth, has characteristics long service life high efficiency; tooth increased, so that lifting capacity, precision production efficiency can be improved; each main edge secondary edge, reliability an polished multiple times, durability increased; detachable matched suitable selected according requirements; application range improved operation convenient fast.
