The coordinate data is transmitted to the cutting system, which rotates 180° counterclockwise to the CNC cutting station 5 for cutting. The cutting system receives the coordinate data and matches it with the template, outputs a cutting command, and performs cutting. After cutting, it rotates 180° counterclockwise (or 180° clockwise) to the loading station 3. The air duct 28 turns off the vacuum adsorption, removes the finished product and cleans the cutting waste, and rotates 180° in a continuous circulation according to the above process.
