During the use of optical fiber laser cutting machine, in order to obtain high-quality cuts, the height from the cutting nozzle to the surface of the workpiece to be cut must be basically consistent. Because of the high speed of the laser cutting machine, the operator can’t see it with his eyes and adjust it by hand. The reaction speed is definitely not up to the standard. Especially when cutting thin plates, or the material surface has lines, the flatness is not high or the cutting and processing environment is limited, it is important to keep the cutting height stable.
When the fiber laser cutting machine is in use, the cutting head will walk according to the set cutting path, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses and different cutting methods. The distance between the cutting nozzle and the surface of the cutting workpiece determines one of the main factors of the cutting quality and cutting speed. In addition to selecting the appropriate cutting nozzle model and air pressure parameters according to the cutting situation, the height between the cutting head and the steel plate needs to be increased or decreased according to the thickness of the cutting material. The steel plate with different thickness uses different parameters. At the same time, the cutting nozzle should be adjusted to the corresponding height.
In order to make up for the unstable height control problem when manually adjusting cutting, the metal laser cutting machine is equipped with an imported follow-up capacitor height adjuster. Metal laser cutting machine can maintain the same height no matter how thick the plate is cut.
The principle of capacitance height adjustment is that the capacitance between two plates is formed between the capacitance induction ring of the laser cutting machine and the steel plate to be cut, and the capacitance is related to the distance between the two.
