UV laser due to the very small focal spot and processing small heat-affected zone, Super fine marking, special materials can thus be marking is marked effect has higher requirements will be billed to customer's product of choice. UV laser removal of copper material, but is suitable for processing the material more widely. Not only good beam quality, smaller focal spot, to achieve Super fine marker; for more widespread; minimal heat affected zone, does not produce heating effects and does not produce material burning problems; marking speed, high efficiency machine performance is stable, small size, low power consumption advantages.
