●When the focus laser spot is adjusted to the minimum, the initial effect is established by spot firing, and the focus position is judged by the
size of the spot effect. As long as the laser spot reaches the minimum, then this position is the optimal processing focal length and then began
●In the first part of the debugging of the laser cutting machine, we can use some debugging paper and workpiece waste to spray to determine
the accuracy of the focal length position, move the position of the upper and lower laser head height, and the size of the laser spot will have
different sizes when it is sprayed.
●After the laser cutting machine is installed, an ascribing device will be installed on the cutting nozzle of the CNC cutting machine, and the
road will draw a simulated cutting figure through the scribing device. The simulated figure is a 1m square. A circle with a diameter of 1m is
built-in, and the four corners are drawn diagonally. After the drawing, use a measuring tool to measure whether the circle is tangent to the four
sides of the square. Whether the diagonal length of the square is√2 (the data obtained from the root number is about: 1.41m), the central axis
of the circle should bisect the side of the square, and the right point where the central axis intersects the two sides of the square to the sides
of the square The distance of the intersection should be 0.5m. By measuring the distance between the diagonal and the intersection point, the
cutting accuracy of the equipment can be judged.
