First of all, we need to understand the function of the cutting head of the fiber laser cutting machine. It is used to randomly track the change of the focus and ensure the constant position of the focus at any time. The constant focus position is an important factor affecting the cutting quality. Here is how to adjust it.
First, adjust the focus fine-tuning knob on the operation panel of the machine tool to the middle.
Second, insert the sensor into the locking piece, and use a multimeter to measure the output of the secondary meter to make the voltage basically zero, and then tighten the screw on the locking piece.
Third, adjust the speed adjustment screw and measure at the same time to make the voltage about 3~6V. The greater the voltage, the faster the follow-up speed, and then tighten the adjustment screw.
Fourth, regularly check whether the positive and negative set screws are pre-tightened, whether the crimping nut is loose, and determine the positive and negative directions (the two directions cannot be interchanged).
Fifth, when the safety protection rod encounters an accident, the rod breaks and the machine tool stops automatically.
