Laser cutting of nylon cloth telescopic dust cover of machine tool is to focus the laser emitted from the laser into a laser beam with high power density through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the laser beam blows away the melted or vaporized metal. With the movement of the relative position between the beam and the workpiece, the material finally forms a slit, thus achieving the purpose of cutting. Laser cutting replaces the traditional mechanical knife with invisible light beam, which has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting to save materials, smooth incision and low processing cost, and will gradually improve or replace the traditional metal cutting process equipment. The protective cover of laser organ cutting is called the guide rail protective cover of flexible organ machine tool, commonly known as the leather tiger. It is a kind of machine tool shield. The shape and size of organ shield can be designed into various styles according to actual needs. This kind of shield has the advantages of small compression and long stroke. Machine tool nylon cloth telescopic dust cover has five shapes: straight, straight, door, square and round. The manufacturing process of nylon cloth telescopic dust cover for laser cutting machine can be divided into the following steps: cutting, fixing, heat sealing (bonding), setting and testing. machine tool
