Laser cutting head basic knowledge XT Laser

When the metal laser cutting machine is in use, the cutting head will walk according to the set cutting trajectory, but under different materials, different thicknesses, and different cutting methods, the height of the laser cutting head needs to be adjusted and controlled. The distance between the cutting nozzle and the surface of the workpiece One of the main factors that determine the quality of the incision and the cutting speed. In addition to selecting the appropriate cutting nozzle model and air pressure parameters according to the cutting situation, the metal laser cutting machine needs to increase or decrease the height between the cutting head and the steel plate according to the thickness of the cutting material. Different thickness steel plates use different parameters. At the same time, the cutting nozzle should be adjusted to the corresponding height.

During the use of the metal laser cutting machine, in order to ensure a high-quality cut, the height of the cutting nozzle to the surface of the workpiece must be kept basically the same. Due to the high speed of the laser cutting machine, the operator can see with his eyes and adjust the operation method by hand, and the response speed is definitely not up to the point. Especially when cutting thin plates, or the surface of the material has lines, the flatness is not high, or the cutting processing environment is limited, it is important to keep the cutting height stable.

In order to compensate for the instability of height control when manually adjusting and cutting, the metal laser cutting machine is equipped with an imported follow-up capacitor height controller. No matter how thick the board is to be cut, the height can be kept consistent with the capacitive height adjustment cutting head.

The principle of increasing the capacitance is: the capacitance between the two plates is formed between the capacitance sensing ring and the steel plate to be cut, and the size of the capacitance is related to the distance between the two.
