What are the daily maintenance work of the engraving machine?

On weekdays, the engraving machine always works and works, and accidentally goes to work. In order to prevent the machine from overworking, we must also pay attention to maintenance while working. Here are the tips for daily maintenance given by experts:
    1. The continuous running time is less than 10 hours per day to ensure the cleaning of the cooling water and the normal operation of the pump. The water spindle motor must not be dehydrated, and the cooling water should be replaced regularly to prevent the water temperature from being too high. In winter, if the working environment temperature is too low, the water in the water tank can be replaced with antifreeze.
    2, each time the machine is used, pay attention to cleaning, be sure to clean the dust on the platform and transmission system, and regularly (weekly) lubricate the transmission system (X, Y, Z three axes). (Note: X, Y, Z three-axis polished rods are maintained with engine oil; high-speed butter is added to the screw; in winter, if the working environment temperature is too low, the PRTT ball screw, polished rod (square rail or circular guide) should be gasoline first. Rinse and clean, then add the oil, otherwise the resistance of the machine transmission part will be too large and the machine will be misaligned.)
    3. When performing maintenance inspection on the electrical appliance, be sure to turn off the power supply, and wait until the monitor has no display and the main circuit power indicator is off.
    4. The engraving machine should be inspected for fasteners for about three months. The connecting screws on both sides of the gantry, the fastening screws of the screw nut, and the fastening screws on both sides of the motor are tightened.

How small laser engraving machines work

       The small laser engraving machine is the most advanced machining equipment at present. The laser is used for the first time in the field of machining, which has brought unprecedented promotion to the development of machining. What is the working principle of a small laser engraving machine? Many people don't know much about small laser engraving machines. Most people have heard of people mentioned in their peers, but don't know what is the basic working principle. Let us give You have a detailed explanation; the laser cutting machine is mainly composed of two parts, one is the CNC workbench, and the other is the machine tool. We can use the CNC workstation to process the drawings and input them. After the operation, the machine will be commanded, and the machine will be designed according to the instructions.

       Small laser engraving machines work in two ways, dot matrix engraving and vector cutting.

* Dot matrix laser engraving: similar to high resolution dot matrix printing. The laser head moves from one side to the other, the engraving points form lines, and then the laser head moves up and down, engraving a number of lines that form images or letters. This method can be used to scan graphics, text and vector graphics.


* Vector Cut: Vector cut is different from dot laser engraving because it is engraved on the contour lines outside the image and letters. We usually use this method to cut wood, acrylic, paper and other materials. It can also be surface marked in a variety of materials.


* Engraving speed: Engraving speed refers to the moving speed of the laser head, usually representing IPS (inches per second), and high speed brings high productivity. Speed ​​is also used to control the depth of cut. For a given laser intensity, the slower the speed, the deeper the engraving. You can adjust the speed through the engraving machine panel, or you can adjust the computer's operating software. 1% to 100%, the adjustment range is 1%. Hummer's advanced motion control system allows you to engrave at high speeds and still get super-fine engraving.


* Engraving intensity: refers to the laser intensity radiation on the surface of the material. For the speed of a engraved print, the bigger the laser is, the deeper the engraving. You can adjust the intensity of the use, and the engraving machine panel can also be used to adjust the operating software of the computer. 1% to 100%, the adjustment range is 1%. The greater the intensity, the smaller the same rate.


* Spot size: The laser beam spot size can be adjusted according to the different focal lengths of the lens. Small-point lenses are used for high-resolution engraving, large-resolution low-resolution engraving, but for vector cutting, it is the best choice.


* Suitable materials for engraving: wood, plexiglass, metal plate, glass, stone, crystal, glass, paper, color plate, aluminum, leather, resin, spray metal.
