Laser engraving machine knowledge

    Using laser engraving and cutting, the process is as simple as printing on paper using a computer and printer. You can use a variety of graphics processing software, such as CorelDraw, in Win98/Win2000/WinXP environment. Scanned graphics, vectorized graphics and various CAD files can be easily "printed" into the engraving machine. The only difference is that printing applies toner to the paper, while laser engraving shoots the laser onto almost all materials such as wood, acrylic, plastic, metal, and stone.
     Laser engraving can be divided into dot matrix engraving and vector cutting according to different engraving methods:
     ◆ dot matrix carving
     Dot matrix engraving resembles high definition dot matrix printing. The laser head oscillates left and right, each time engraving a line consisting of a series of points, and then the laser head simultaneously moves up and down to engrave a plurality of lines, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be carved using dot matrix.
     ◆Vector cutting
      Unlike dot matrix engraving, vector cutting is performed on the outer contour of the graphic. We usually use this mode to perform penetrating cuts on wood, acrylic, paper, etc., as well as marking on a variety of materials.
     The performance of an engraving machine is mainly determined by the engraving speed, engraving intensity and spot size.
     ◆Engraving speed
      Engraving speed refers to the speed at which the laser head moves, usually expressed in IPS (inches per second), which results in high productivity. Speed ​​is also used to control the depth of the cut. For a particular laser intensity, the slower the speed, the greater the depth of the cut or engraving. You can adjust the speed with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The advanced motion control system of the Hummer makes you get super-fine engraving quality when you are carving at high speed.
     ◆Engraving strength
     Engraving intensity refers to the intensity of the laser that strikes the surface of the material. For a particular engraving speed, the greater the intensity, the greater the depth of the cut or engraving. You can adjust the intensity with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The greater the intensity, the greater the speed. The depth of the cut is also deeper.
     ◆ spot size
     The beam spot size can be adjusted using lenses of different focal lengths. Small spot lenses are used for high resolution engraving. Large spot lenses are used for lower resolution engraving, but for vector cutting, it is the best choice. The standard configuration for the new device is a 2.0 inch lens. Its spot size is in the middle and is suitable for all kinds of occasions.
     The general engraving machine can engrave the following materials: wood products, plexiglass, metal plates, glass, stone, crystal, Corian, paper, two-color plate, alumina, leather, resin, spray metal.

How can a woodworking engraving machine not be damaged by the knife?

        Today, we will talk about how the woodworking engraving machine can not be damaged by the knife. This topic, if you want to know the friends, then let me follow the small series now.
        At the beginning is the parameter setting problem. The time when the carpenter engraving machine is positioned in the Z axis is not to let the knife meet the data surface, but to remove the data so that the knife directly encounters the table. It can be encountered, not deep, in this place. The Z axis is first zeroed, and then the cutting depth set in Venter is at the corresponding height, and then the Z axis is zeroed. This is the origin of the Z axis. According to the depth of the setting of Wentai, the lowest point of the engraving machine is the first place where our door is zeroed. It is just below the table, so that the data is completely engraved and will not hurt the engraving machine.

        Secondly, it is better to add a cover plate on the surface of the engraving machine. For example, the carpenter engraving machine with vacuum suction table can put a thin Ozon plate on the table. The looseness of the Ozon plate itself will not affect the vacuum adsorption, and it can effectively prevent it. A tool that is not allowed to be formed at the origin setting has a problem with the table.

        The surface of the carpenter's engraving machine can be scratched in the application even if it is done in the temporary application. This time, it is necessary to use the new milling platform. When the electric board or PVC on the table is too thin, it can You can build a new layer. What needs to be noticed is that in the time of the factory, in order to prevent damage to the countertop during the logistics and transportation, the normal city needs the time for the after-sales staff to debug the door from the new milling platform.
