After the installation of the laser cutting machine is completed, a marking device will be installed on the cutting nozzle of the CNC cutting machine. Through the marking device, a simulated cutting diagram will be drawn, simulating a 1m square. The built-in diameter is a 1m circle, and diagonal lines are drawn at the four corners. After drawing, use a measuring tool to measure whether the drawn circle is tangent to the four sides of the square. Is the length of the diagonal of the square √ 2 (the data obtained by the square root sign is approximately: 1.), the central axis of the circle should be evenly divided into the edges of the square, and the distance between the central axis and the intersection of the square should be 0.5m. The cutting accuracy of the equipment can be determined by testing the distance between the diagonal and intersection points. Laser cutting machines. The walking accuracy of the mechanical transmission part can be achieved through screw transmission or plastic rack transmission; The laser cutting machine utilizes a plasma arc to pass through the surface of the material to achieve the cutting effect. Considering the shape of the plasma arc and the penetration steps of the material, the plasma arc often cuts more metal from the upper and lower parts of the incision, making the end face of the incision slightly inclined. The upper edge is generally square, but sometimes slightly circular. The possible issue here is the distance between the two cutting surfaces at the upper edge of the incision caused by the cutting beam. When the upper edge of the incision melts, the distance between the two cutting surfaces near the melting layer is abnormal. The flatness of the cutting surface refers to the distance between the highest and lowest points on the cutting surface measured according to the inclination direction of the cutting surface. 2. Cutting equipment: The nozzle aperture of the cutting gun is very important, usually cutting thin plates with a 1.0 hole. The cutting pressure can be increased as much as possible with reliable arc ignition. Cutting current: While ensuring cutting efficiency, adjusting the current appropriately can reduce cutting seams. 3.
