With the popularity of laser cutting machines, customers have more and more requirements for laser cutting machines. For example, if you want a laser cutter to cut various shapes, it is not as simple to use a laser cutter to cut a round hole as in the picture. Below, Qingyuan laser editor in chief shares with you some points that you need to pay attention to when cutting a round hole with a laser cutter:
1. Laser cutting machine cutting 1:1 hole is the best scheme. The larger the hole diameter, the better the cutting. The laser cutting machine with insufficient ability will cut small holes with irregular round holes and too many breakpoints left.
2. The gas pressure is too high or too low. If the gas pressure is too high, the hole will burst, and if the pressure is too low, the cutting edge will be rough and the burning will be serious. Choosing proper gas pressure is one of the reasons to solve the irregular cutting of round holes.
3. Servo motor parameters. Many parameters of servo motor are related to circular motion. Improper parameters and mismatching of X and Y axes will cause ellipses or irregular shapes in cutting circular holes. Laser cutting machine
4. The accuracy of lead screw or guide rail is not enough. The technical strength and workers' level of some small factories are not high, and the precision of the laser cutting machine produced is less than 0.1mm, so the precision of the circular hole cut can not meet the requirements.
