The first way: Because in the focus of laser cutting machine spot is the least, press the “Aim”button, according to the height of spot to clear the focal length. That is, in the play spot the most hours, can be considered cutting objects when the laser head of the better aspect ratio.

That is, put an object under the laser head, adjust the height-to-width ratio of the laser head. When the laser head is positioned with a different height-to-width ratio, press the “Aim”button to see the size of the light spot. First, the position of the laser head can be adjusted more rapidly, we find the area where the aspect ratio of the laser head is small, and then adjust the aspect ratio of the laser head in this area. The way of adjusting focal length of laser cutting machine

The second way: Because in the laser cutting machine laser focal length, light intensity is the strongest, according to self-check, the laser hit on the object height to identify the focal length of the site. That is, put an object under the laser head, adjust the height-to-width ratio of the laser head, in the laser head position and different height-to-width ratio, long press the “Precise positioning”key for about 3 seconds above, when the drawing is deep, can Be considered the laser head of the better aspect ratio. That’s the aspect ratio of the laser head that we’re going to adjust.

The above is a clear general term for the focus of the laser cutting machine, so in cutting different product parts, different raw materials, the focus of the laser cutting machine will be selected differently, the following is the focus of the laser cutting machine and the middle of the relationship between the material: First, focal length cutting, focus on the product surface. Laser cutting machine cutting stainless steel plate, galvanized steel plate and other products when the method used. As the focus is on the upper surface of the product, therefore, the upper surface of the peripheral cutting smooth and clean, while the lower surface of the peripheral is uneven. Second, the focal length, the focus in the product inside the workpiece. Laser cutting machine cutting stainless steel plate, aluminum products such as the use of workpiece methods. The focus is in the middle, so the area of smooth surface is large, the cutting width is wider than the zero focal length, the cutting gas pressure is larger, and the hole breaking time is longer than the zero focal length.
