The focus on the surface of the plate corresponding to the focus value of 0 is called zero focus, in the cutting machine process parameters, the focus is usually set to zero focus, so that the cutting seam can be the smallest. However, in the actual operation setting, the laser focus may have some deviation, the greater the deviation, the larger the slit. Laser cutting machine as a high-precision cutting equipment, widely used in all walks of life, the following intelligent laser cutting equipment manufacturers detailed how to set zero focus.
1. slit size observation method
You can set different focus values on the laser cutting machine, such as positive 3, positive 2, positive 1, zero, negative 1, negative 2 and negative 3, and then cut a straight line on the plate, the cutting speed can be adjusted slower to ensure that the plate can be cut through. Then observe the change of slit size to find the position of the narrowest slit, that is, the zero focus position.
2. Use the focus test function
Most laser cutting machine system comes with a focus test function, as long as the test parameters are set according to the system requirements, the system can automatically find the zero focus position.
The zero focus position is very important for the process cutting effect, so it is necessary to find the zero focus position when the equipment process debugging, so that the cutting quality is the best!
