Common faults and adjustment methods of laser marking machine

Common problems and adjustment methods of laser marking machine Common problems:

1. The reason why the laser marking machine cannot reach the expected marking depth:

★ Whether the laser output power meets the requirements;

★ Whether the turn-off power of the acousto-optic switch meets the requirements;

★ Whether the light path adjustment is accurate;

★ Whether the surface of the workpiece is on the focal plane;

2. After the laser marking machine has been used for a period of time, the reason why the laser output power of the laser decreases:

★ Whether the laser resonant cavity has changed: fine-tune the front and rear resonant cavity lenses to make the output spot extremely good;

★ Whether the total reflection and output diaphragm are fouled;

★ Condensation is formed on the surface of the laser bar of the laser marking machine due to the temperature difference;

3. The laser output power of the laser marking machine is normal, but the laser beam cannot play a marking role:

★ Whether the adjustment of the optical path system is accurate;

★ Whether the sound and light switch can play a switch role;
