Simple method for metal laser cutting machine to process sheet metal
Many industries need to process metal sheets, so it is inevitable to wake up and cut metal sheets. The metal laser cutting machine is the best tool for cutting sheet metal. So is there any easy way for metal laser cutting machine to process metal sheet? Metal laser cutting machine is very important to determine the positioning focus when processing metal sheet. There are three easy ways to determine it: 1. Printing method: use the cutting head Moving from top to bottom, laser beam printing is performed on the plastic plate, and the spot with the smallest printing diameter is the focus. 2. Inclined plate method: Use a plastic plate placed obliquely at an angle to the vertical axis to pull it horizontally to find the smallest point of the laser beam as the focus. 3. Blue spark method: remove the nozzle, blow air, hit the pulse laser on the stainless steel plate, make the cutting head move from top to bottom, until the largest blue spark is the focus. For the cutting machine of the flying optical path, due to the beam divergence angle, the optical path length of the near end and the far end of the cutting are different, and the beam size before focusing is different. The larger the diameter of the incident beam, the smaller the diameter of the focal spot. In order to reduce the change of the focal spot size caused by the change of the beam size before focusing, domestic and foreign laser cutting system manufacturers provide some special devices for users to choose: 1, collimator, which is a common method, namely A collimator is added to the output end of the CO2 laser for beam expansion, the beam diameter after beam expansion becomes larger, and the divergence angle becomes smaller, so that the beam size at the near end and the far end before focusing is close to the same in the cutting working range. 2. Add an independent lower axis of the moving lens to the cutting head, which is two independent parts from the Z axis that controls the distance between the nozzle and the surface of the material (standoff). When the machine tool table moves or the optical axis moves, the beam moves from the proximal end to the distal F axis at the same time, so that the beam spot diameter remains the same in the entire processing area after the beam is focused.
