How to solve the problem of laser marking machine-No laser

Laser marking machine is that laser beam mark permanent marks on a variety of different material surfaces.Marking is the evaporation of surface material to expose the deep material, so as to carve out the exquisite patterns, trademarks and text. Laser marking machine is divided into, CO2 laser marking machine, play semiconductor laser marking machine, laser fiber play standard machine, YAG laser marking machine, the laser marking machine is mainly used to require some finer, the higher accuracy of the occasion. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware, tools, accessories, precision instruments, watch glasses, jewelry, auto parts, plastic buttons, building materials, PVC pipe.
But if the laser marking machine meet the problem-no laser,how should we do?
Fault phenomenon: the laser is not normal, in the high voltage side, the string into the current table, the current table shows the exception, or on a long time there is a current, or sometimes no, sometimes not controlled.The main reason is that the type of laser is not selected, the main board, the wiring board, the power supply or the control line and the cooling water cycle system.

Elimination method:        
1,Parameter settings, see if the type of laser is correct, it is the main reason for the failure of continuous light.  
2,Pull the nine core control line, to see whether there is a control line loose. Connection is not reliable.        
3,The power supply control line (nine cell lines) removed, according to the key burst of laser power supply, the power supply is still a motherboard failure analysis.
4.Press laser,if can out laser,that shows the laser power supply is well.
5.If press laser,can not our laser,that shows the laser power supply has problem.
6.When the power supply is well, connected to the control line, with a multimeter measuring connection plate on the switch control pin, no light, normal voltage in more than 4 volts, less than 3 V, motherboard output is not well; light emitting, the voltage should be below 2 volts, higher than 2.5 V output is not well.
7.Check whether the water cycle is well,the water flow is enough, whether there is a problem of water protection.

Improve the efficiency of laser cutting machine

Improve the efficiency of laser cutting machine 

Laser cutting machine is mainly using laser beam to the plate surface and release energy to see steel melting and evaporation, because energy is highly concentrated can rapid local heating to melt and vaporize steel plate, because the energy is concentrated, just only a small amount of steel reached other parts, basic not caused any deformation, using laser can produce complex shape of the workpiece, the cutting of the workpiece, the does not need for the next step processing can be used directly.
Laser cutting machine has three advantages: good cutting quality, fast processing speed, clean, safe, no pollution, in the production of laser cutting machine power is certain, so I want to improve efficiency, it is necessary to adjust operation.

1 The learning and manipulation of new machines           

In the process of operation, the operator needs to strengthen the learning and skills of the machine performance through the daily production. To will work on an alternative practice, spare time to strengthen the machine in all aspects of knowledge learning, do meet machine appear small problem can be solved, the problem appeared to know where the problem lies, and help solve the problem.

2 Know how to modify the CNC cutting procedures           

For CNC laser cutting machine, make changes to the program, using linear surgical method, will drive up to the point on the arc, the cutting down of circular cross section is very smooth, to ensure that the quality of the parts.

3 Optimize the scheduling scheme           

Through consultation and the fish Technology Department of the workshop, the two beam sharing a common edge cutting, this does not affect to the cutting effect, so the efficiency is to artificially raise.
