Laser engraving machine Note 1, the use of automatic focus, to pay attention to the automatic measurement focus rods must be tightened, otherwise the work surface to the top of the laser. 2, laser engraving machine at work, prohibit open the cover. 3. Open the smoke when working, blowing smoke devices. 4, processing of wood, paper, must pay attention to the processing speed to avoid fire. 5, the initial user to be irregular red light positioning process. 6, processing thin wood, when volatility materials, to adjust the amplitude water for little more than 1mm. 7. When a small laser cutting laser machine, the workpiece holder to use more than 2 cm away from the table. 8. Clean the reflector lens and the focal length of the lens: two-finger pinch reflex lenses. The other hand hold the camera lens cleaning paper to clean the lens. 9, the amount is usually carved file, the resolution should be higher, carving point Chen file, the resolution should choose low point. Laser engraving machine laser tube failure points 1. Installation fulcrum to be reasonable, the fulcrum should be 1/4 of the total length of the laser tube, or cause deterioration of the laser tube spot mode, some working for some time to become a spot a few points, resulting in laser power down not meet the requirements, resulting in constantly changing tubes, carefully read the "Note the use of the laser tube." 2. The cooling system grounded, regular cleaning of water tanks and water, cooling water tank thermostat to a reasonable temperature control point laser laser engraving machine, otherwise the laser tube easily damaged and cause condensation power down, cold water header pipe off, life is shortened, sometimes Unable to work, resulting in constantly changing tubes. 3. Water protection should always check the cleaning, cooling water is often not red water protection water protection float switch or float switch is not reset, the method can not be used to solve the pressing short. Cooling water quality is better, faucets aluminum oxide is too serious a period of time should be regularly cleaned using pumps and pipes, water protection in the dirt laser laser machine price, or cause pipes to burst or cold laser head off. The suction device should be checked regularly to clean laser laser machine, the fan duct to clean up. Otherwise, do not go out a lot of smoke dust discharge, severe pollution fast lens and laser tube, so that all mechanical and electronic components susceptible to oxidation caused by bad contact. 5. Check the focusing lens and mirror work for a frame on the heat, the lens surface rust discoloration; Tuomo cracking belong to the object to be replaced, especially a lot of customers with a large air pump and air compressor, so the focus of the lens the water quickly, so you must check the cleanliness and quality is good or bad time lens (laser tube light mouth) optical system.
