More and more companies are beginning to use laser cutting for circular holes because of the flexibility and efficiency of laser pointer processing methods. The speed of the 500W fiber laser cutting machine at 90 meters per minute is enough to meet the high-speed requirements of many sheet metal processing plants. In addition, the circular hole section of laser processing is smoother and the diameter of the circular hole can be infinitely modified to meet the diverse needs of the factory .
However, machining circular holes with a laser cutting machine is not very simple, but requires some skills. Let the laser engineer analyze the reasons and precautions for the problem of cutting round holes. During the blowing process, when the air pressure is too small, slag scraping and charring will occur. If the pressure is too high, the hole will easily burst. So this requires the perfect cooperation between the process proofer and the machine. Based on experience, the appropriate air pressure is selected to make the round hole fuller.
The best solution for laser cutting machine to cut round holes is the round hole ratio of 1: 1, which means that the ratio of aperture to plate thickness is 1: 1. Of course, this ratio, that is, the larger the hole diameter, cuts out high quality circles Holes are easier. Otherwise, when the energy of the fiber green laser pointer cutting machine is insufficient, the cutting small holes are prone to residual point breaks and round holes are not round. Round holes sometimes appear elliptical or irregular. This is related to the mismatch of X \ Y axis movements, and the direct reason for the mismatch of X \ Y axis movements is that the servo motor parameter adjustment is inappropriate. Therefore, the quality of cutting circular holes also has certain requirements on the servo motor.
