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 air, let the pulse laser on the stainless steel plate, make the cutting head from top to bottom movement, until the blue spark is up to the largest focus.
   3. Beveled focus burning method: With the vertical axis into an angle of the plastic plate to make the horizontal pulling, looking for the smallest point of the laser beam as the focus of laser cutting machine.
   4. CNC positioning punch method: The cutting head make maving from top to bottom, and the laser beam is printed on the plastic plate. Print diameter minimum area is the focus.

   The focus position is an important factor that affects the quality of laser cutting machine. When the focus is in the best position, the cutting gap is the smallest and the efficiency is the highest. The best cutting speed can get the best cutting effect, For cutting parts with high precision or large thickness, it is necessary to master the technology of locating the laser cutting machine focus.
