Laser cutting machine after a period of time, cutting accuracy will have some error, this error is often due to changes in the focal length caused. So, how to master the accuracy of the operation is necessary to operate laser cutting machine, the following Xiaobian to give you universal about.
Laser cutting machine precision debugging method:
1. When the spotlight of the focus laser is adjusted to the minimum, the initial effect is determined by the spotlight, and the focal length is determined by the size of the spot effect. We only have to look at the laser light to the minimum, so this position is the best Processing focal length, and then start processing work.
2. In the front part of the laser cutting machine debugging, we can use some of the test paper, the workpiece scrap to determine the accuracy of the location of the focal length, move the upper and lower laser head height position, the laser spot size will have different size changes. Repeatedly adjust the position to find a minimum of a spot position to determine the focal length and the best position of the laser head.
3. Laser cutting machine in the installation is completed, the cutting edge of the CNC cutting machine is equipped with a scribing device, through the crossed device to draw a simulation cutting graphics, simulation graphics for the 1m square. Built a diameter of 1m round, four corners were drawn diagonal, after the draw, with the measurement tool to measure the circle is not tangent with the square of the four sides. Square diagonal length is √2 (open root number of the data is about: 1.41m), the circle of the central axis should be bisected square side, and the central axis and the square side of the two points to the square of the intersection The distance should be 0.5m. Test the distance between the diagonal and the intersection, you can determine the cutting accuracy of the device.
