3. The utility model is made of a composite material of a 3D printed shell and a hard concrete filler, and adopts a vacuum adsorption method, on one hand, a profiling sealing groove is designed by utilizing 3D printing forming, so that a good vacuum environment can be established for tools and parts, and sufficient suction is provided for cutting; on the other hand, the hardness of the concrete material is utilized, the cutting force can be well resisted in the middle-low load and non-impact cutting process, the air vent is formed in the tool, the part and the tool are sucked together by using vacuum adsorption, clamping tools such as a pressing plate and the like are omitted, the process design is greatly simplified, the profiling positioning and the sealing flange are used, the vacuum pump is matched, and the part is easily fixed. The fine positioning pin hole and the fine positioning pin which are formed by fine machining can be additionally used for realizing the fine positioning in the horizontal direction.

4. According to the utility model, the sealing flanges surround the outer contour and the inner hollow contour of the part, a watertight complete area can be formed, the compactness is increased, and thus the fixing force of the part is increased. The height of the sealing flange is slightly higher than the edge of the part by 3-5mm, so that the sealing reliability is further enhanced.
