Lasergravering er brugen af laserteknologi til at gravere. Princippet er at bruge afbrænding af laservarme eller kemiske ændringer på den graverede overflade til at producere graveringsmærker.
Sammenlignet med håndholdte-værktøjer er fordelene ved lasergraveringsmaskiner, at den graverede tekst og mønstre kan kontrolleres, størrelsen kan kontrolleres, og de graverede mønstre er også relativt fine. Ulempen er, at den ikke er så tre-dimensionel som manuel fysisk gravering. Derfor bruges lasergraveringsmaskinen hovedsageligt til overfladisk mærkning.
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.
Den traditionelle graveringsmaskine drives af en stepmotor eller en servomotor. På grund af laserens egenskaber har mange moderne maskiner naturligvis brugt et galvanometersystem til at styre laserens position ved at kontrollere den lille bevægelse af linsens vinkel.
Laserlyskilden er kernekomponenten i lasergravering. Lyskildens egenskaber bestemmer laserfunktionens materialeeffekt for at opnå gravering. Energiniveauet har en væsentlig indflydelse på graveringsdybden og -hastigheden.
Klassificering af lyskilden til lasergraveringsmaskine
På nuværende tidspunkt omfatter de almindelige lyskilder til lasergraveringsmaskiner på markedet hovedsageligt CO2-lyskilder, fiberlyskilder, lilla lyskilder, grønne lyskilder og diodelyskilder. Laserbølgelængden er forskellig, og graveringseffektiviteten er også meget forskellig
Blandt dem er CO2-lasergraveringsmaskine hovedsageligt velegnet til ikke-metalliske materialer såsom træ, læder og plast.
●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.
Udvælgelseskriterier for lasergraveringsmaskiner
Jeg tror, at mange venner, der ønsker at købe en lasergraveringsmaskine, er mest bekymrede over dette problem. Alle ønsker bestemt at vælge en praktisk og overkommelig lasermaskinetype. Så før du vælger, kan du forstå fordelene og ulemperne ved forskellige lasermaskiner
●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
