Laser engraving machine troubleshooting

- Oct 17, 2017 -

1. The cooling system to be grounded, often cleaning the water tank and water, cooling temperature control tank temperature control point should be reasonable, otherwise the laser tube is easy to damage and condensation power down, the tube cold head off, life greatly shortened, sometimes unable to work, Resulting in constant change.

2, water protection should always check the cleaning, cooling water often can not open the water to protect the float switch or water protection float switch is not reset, can not use short circuit to solve the urgent needs. Cooling water quality is better, water nozzle aluminum oxide is too serious, the use of a period of time will regularly clean the pump and water pipes, water protection in the dirt, or cause the laser tube burst or cold head off.

3, the suction device should be regularly cleaned, the fan duct clean up. Otherwise, a lot of smoke and dust do not row out, serious and rapid pollution of the lens and laser tube, so that the mechanical parts of the electronic parts easily oxidized contact is not good.

4, focusing mirror and mirror inspection, work will be a frame on the fever, the lens surface color rust; stripping cracking are belong to the object to be replaced, especially many customers with air pump and air compressor, so in focus lens On the soon on the water, it must be checked on time (laser cutting) optical system cleaning and quality is good or bad.

5, the machine working environment can not be too bad, if the ambient temperature is higher than 30 degrees, less than 18 degrees, too much dust, air pollution is serious, so that the machine severely damaged, the failure rate continues to rise; moisture environment, the electrical accessories is easy A problem. So in this special remind customers to improve the working environment and the machine often maintenance.

6, with the power grid to match. The whole part of the equipment power distribution and contact points to be good (fan, water cooler, laser machine, laser power, the computer to an independent power supply).

7, the laser tube operating current should be reasonable, can not be long-term in the 90-100 light intensity work; to rationalize the application of laser and save laser energy; optical system to clean the correct, otherwise cause the laser tube premature aging and rupture, so the laser machine working time Strong should be adjusted in 50-60%, and then according to the material to adjust the working speed, this is the best working state of the laser tube.
