The laser marking machine is a high-precision industrial processing equipment, and it is prone to some emergencies after a long time of use. For example, many users have found that the power of the laser marking machine has dropped. There are many reasons for the power drop of the laser marking machine. 01 Reason: The laser power supply voltage drops, resulting in a drop in laser output power. Solution: The power supply needs to be replaced. 02 Reason: The lenses and lens are defaced. Solution: Clean or replace. 03 Reason: The optical system is not accurate. Solution: Adjust the laser or adjust the position of the beam expander. The incident light must be at the center of the light entrance hole of the beam expander, and the outgoing light must be at the center of the light exit hole. 04 Reason: The workpiece surface is not on the focal plane. Solution: adjust the workpiece surface to focus. 05 Reason: The position and direction of the beam combiner are not accurate. Solution: Adjust the position of the beam expander. 06 Reason: The service life of the equipment is too long. Solution: It needs to be inflated or replaced with a new laser. 07 Reason: The laser of the vibrating mirror deviates from the center. Solution: adjust the laser. 08 Reason: The marking speed is too fast. Solution: Properly slow down the marking speed. Reminder: During the maintenance and repair of the laser marking machine, some operations need to be completed by professional technicians. Do not disassemble and repair by yourself, otherwise it will not only damage the performance of the equipment, but also may cause harm to the operator.
