How To Locate The Laser Cutting Machine Focus?

How To Locate The Laser Cutting Machine Focus? With the development of science and technology, Laser cutting machine has been widely used in all walks of life. Meanwhile with the improvement of people living standard, the requirements of the crafts constantly refined, so we need continuously improve the precision of laser cutting machine. But how to locate the laser cutting machine focus? this is a very concerned topic when we do the first step of cutting, the following are points we summarized about how to locate the laser cutting machine focus. 1. Collimator: This is a very common approach, add a collimator tube at the outputs of CO2 laser to achieve the expansion of the CO2 laser beam, The beam diameter becomes larger and the divergence angle becomes smaller while after the beam expansion, so that make sure the beam size is close to the front end and the far end before cutting. 2. Blue spark technique: Remove the nozzle, blow the...
