The utility model belongs to the field of machine tools. The machine tool chip removal device comprises a base, the problems that in the machining process of an existing machine tool, chippings splash, so that short-distance observation machining cannot be conducted, and chipping cleaning is troublesome are solved. Proposed now is the following scheme, case, one side of the case is connected witha machine tool clamp; a workpiece is connected into the machine tool clamp. A vertically-arranged supporting plate is fixed to the side wall of one side of the case and located above the machine toolclamp, a protection box is slidably connected to the side wall of the bottom end of the supporting plate, a first through hole is formed in the side wall of one side of the protection box, a second through hole is formed in the side wall of the other side of the protection box, the machine tool clamp penetrates through the first through hole, and a workpiece penetrates through the second through hole. According to the utility model, a part machined by a machine tool can be protected, short-distance observation by workers can be facilitated, chippings can be collected and prevented from splashing everywhere, the chippings can be collected and discharged, the operation is simple, the operation by the workers is facilitated, and the convenience is improved.
