Laser cutting accuracy is the key factor to measure the cutting quality of laser cutting machine. So, how can we achieve high accuracy in laser cutting? After years of practice, Xinquanli Laser has summarized several key technologies to improve laser cutting accuracy:

1. Focus position control technology. The smaller the focal depth of the focus lens, the smaller the diameter of the focal spot, so it is very important to control the position of the focus relative to the surface of the material to be cut.

2. Cutting and piercing technology. For any thermal cutting technology, except for a few cases, which can start from the edge of the plate, a small hole must be drilled on the plate. In the laser stamping compound machine, a punch was used to punch a hole first, and then the laser was used to cut from the small hole.

3. Nozzle design and airflow control technology. When laser cutting steel, the oxygen and focused laser beam are shot to the material to be cut through the nozzle, thus forming a gas flow beam. The basic requirements for air flow are that the air flow into the incision should be large and the speed should be high, so that enough oxidation can make the incision material fully conduct exothermic reaction; At the same time, there is enough momentum to eject the molten material.
