Metal laser cutting machine is mainly used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal external processing and other manufacturing and processing industries.
Metal laser cutting machine mainly for cutting carbon steel, silicon steel, stainless steel, aluminum alloy, titanium alloy, galvanized plate, pickling plate, aluminum zinc plate, copper and other metal material cutting. High cutting precision, good stability:
Metal laser cutting machine adopts precision ball screw drive mechanism, optimized NUMERICAL control system control, can meet the precision parts processing, and stable dynamic performance, sustainable long time work cutting section quality is good:
Metal laser cutting machine adopts mechanical moving cutting head system, cutting head moves with the plate height, cutting point position always remains unchanged, so that the seam is flat and smooth, the section does not need post-processing, adapt to flat or curved plate cutting.
Metal laser cutting machine for thin plate cutting can replace CO2 laser cutting machine, CNC punch and shearing machine, etc., the whole machine cost is equivalent to 1/4 of CO2 laser cutting machine, 1/2 of CNC punch.
Metal laser cutting machine is realized by using the high power density energy generated after laser focusing. Its use of precision ball screw transmission mechanism, optimization of numerical control system control, can meet the precision parts processing, and dynamic performance is stable, sustainable long time work, so in metal cutting. The cutting precision of metal can affect the cutting process, so how to control the cutting precision of metal laser cutting machine in use?
1, laser melting cutting does not need to make the metal vaporization, the required energy is only 1/10 of the vaporization cutting.
2, laser vaporization cutting material vaporization heat is generally very large, so laser vaporization cutting requires a lot of power and power density.
3, laser oxygen cutting reaction produces a lot of heat, so the energy required by laser oxygen cutting is only 1/2 of the melting cutting, and the cutting speed is far higher than the dry laser vaporization cutting and melting
4 laser scribing and control fracture:
Laser scribbling is the use of high energy density laser scanning on the surface of brittle material, so that the material is heated to evaporate into a small groove, and then apply a certain pressure, brittle material will crack along the small groove.
Controlled fracture is the use of steep temperature distributions generated during laser grooving to generate local thermal stress in the brittle material, causing the material to break along the small grooves.
Compared with the traditional plate processing method, laser cutting has the advantages of high cutting quality (incision width, small heat affected area, smooth incision), high cutting speed, high holy (can be cut arbitrary shape), wide material adaptability and so on.
Maintenance of metal laser cutting machine
1 Linear guide rail Add lubricating oil to the guide rail
Metal laser cutting machine use for a period of time, cutting the smoke mold, dust has corrosion effect on the guide rail, so to maintain the guide rail on time. Power off the metal laser cutting machine, clean the guide rail with a clean soft cloth, then drop the lubricating oil on the guide rail, oil in the slide back and forth in the paint move, ensure that the lubricating oil into the inner slider. After oiling, let the slider come on the guide rail
Roll back, then must first install the guide rail, pay attention to install the guide rail without first fixed, to fix all the fixed nails, maintain the level, in the belt and slider fixed, and then the lens installed. Dimmer the X's direction and that's it.
2 Mirror focus mirror scrub
After metal laser cutting machine is used for a period of time, smoke and dust will adhere to the appearance of the lens, and will harm the engraving and cutting accuracy. Usually within a week or so (depending on the frequency of the metal laser cutter), three mirrors and one focusing mirror are carefully scrubbed with anhydrous ethanol.
3. Oiling the bearings
Metal laser cutting machine uses a lot of bearings, in order to ensure good cutting, some bearings must be refuelled on time (other than oil-bearing), wipe off the floating soil on the bearing with a clean soft cloth, suck the oil into the needle, then gradually inject the bearing with a needle, and gradually rotate the bearing when oiling.
4. Maintenance of laser tube
The laser tube in the metal laser cutting machine is cooled by circulating water. After long use, there will be some white scale in the tube. We can also add a little food in the circulating water
Vinegar, remove the ditch in the tube, and then clean the laser tube internal circulation with clean water, so that the laser tube will be in the working state, the service life will increase
