Lasersko graviranje je uporaba laserske tehnologije za graviranje. Načelo je uporaba sežiganja laserske toplote ali kemičnih sprememb na vgravirani površini za ustvarjanje gravurnih oznak.
V primerjavi z ročnimi{0}}orodji so prednosti laserskih strojev za graviranje v tem, da je mogoče nadzorovati vgravirano besedilo in vzorce, nadzirati velikost, vgravirani vzorci pa so tudi relativno fini. Pomanjkljivost je, da ni tako tridimenzionalno-kot ročno fizično graviranje. Zato se laserski gravirni stroj uporablja predvsem za plitvo označevanje.
The concept is clear, let's talk about the structure of the laser engraving machine. The realization of the engraving function of the laser engraving machine mainly requires software control, mechanical transmission, and several major components of the laser light source. It is used to edit picture text, adjust parameters and start and stop.
Tradicionalni gravirni stroj poganja koračni motor ali servo motor. Seveda so zaradi lastnosti laserja številni sodobni stroji uporabljali sistem galvanometra za nadzor položaja laserja z nadzorovanjem drobnega gibanja kota leče.
Laserski svetlobni vir je osrednja komponenta laserskega graviranja. Značilnosti svetlobnega vira določajo materialni učinek laserske funkcije za doseganje graviranja. Raven energije pomembno vpliva na globino in hitrost graviranja.
Klasifikacija vira svetlobe laserskega graviranega stroja
Trenutno so običajni svetlobni viri strojev za lasersko graviranje na trgu predvsem svetlobni viri CO2, svetlobni viri iz vlaken, vijolični viri svetlobe, viri zelene svetlobe in diodni svetlobni viri. Laserska valovna dolžina je drugačna, zelo različna pa je tudi učinkovitost graviranja
Med njimi je CO2 laserski gravirni stroj večinoma primeren za ne-nekovinske materiale, kot so les, usnje in plastika.
●Optical fiber light source, the main materials for engraving are metal or materials with a relatively high density of paint. Wood is generally not easy to carve unless it is extremely dense and hard.
●Purple light source, is a relatively high-end light source, the engraving is very fine and the engraving range is wide
●Green light source, we may have seen many three-dimensional images in the middle of acrylic, generally engraved with green light source. Can engrave transparent glass and other materials
●Diode light source, which is originally a light source for stage lighting, has achieved a gorgeous turn in the laser engraving industry. Its engraving principle is somewhat similar to lighting a cigarette butt under the sun with a magnifying glass.
Kriteriji za izbiro laserskih gravirnih strojev
Verjamem, da je veliko prijateljev, ki želijo kupiti stroj za lasersko graviranje, najbolj zaskrbljeni zaradi tega vprašanja. Vsak si zagotovo želi izbrati praktičen in cenovno ugoden tip laserskega stroja. Pred izbiro torej lahko razumete prednosti in slabosti različnih laserskih strojev
●CO2 laser engraving machine: Advantages of engraving wood, leather, plastic, rubber, etc., with high power, fast engraving speed and high precision. Disadvantages The machine is bulky and generally 40-50 kg, it is not easy to move, and the price is generally moderate. Suitable for factories
●Fiber laser engraving machine, advantages: high engraving accuracy and fast speed, suitable for batch operation in factories and can be connected to factory automation production lines. Disadvantages The machine is generally more expensive about 15,000 yuan or more, and the volume is relatively large and the weight is more than 30 kilograms.
●Purple laser engraving machine, advantages: wide range of engraving materials, both metal and non-metal can be engraved. One machine can be used for multiple purposes. Disadvantages Expensive, because of the characteristics of the purple light source, the machine is generally more than 20,000 to 30,000 yuan, and the machine is also relatively heavy. Applicable to high-end manufacturing
●Green laser engraving machine, advantages It can realize three-dimensional engraving and 3-dimensional positioning engraving. The disadvantage is that it is bulky and expensive
●Diode laser engraving machine, advantages, low price, as low as less than 1,000 yuan, generally not higher than 3,000 yuan, small size and easy to move. Disadvantages The engraving speed is slow, and pure metal cannot be engraved. Due to the speed limit, it is generally more suitable for personal DIY home use, or small-scale customization for small and medium-sized businesses
