Common Troubleshooting of laser cutting machine(a)

Sinowaterjet laser cutting machine

Symptom

Analytical methods

Approach

Switched continuous light

1, first check the motherboard parameters, the laser mode is correct

Laser mode is "analog" or "Double laser control"

2. Bad wiring board or keypad bad

Replace the patch panel or keypad

3. Laser power failure

Replace the laser power

4. motherboard failure

Replacing the motherboard

Work-high voltage

1. First, determine the location of high voltage ignition, the case of the laser tube and laser power supply connection at high pressure, to see if placed correctly or joint holder under high pressure wet

The adapter card in the insulating support or use a hairdryer to dry damp section

2. Check whether the high-pressure fittings butt firmly, with or without a virtual company, Weld phenomenon

Ensure no empty spot even, firm butt

3. If the power supply inside the laser ignition

Replace the laser power

4. After the laser cutting machine is still sparking ignition or replace the high-side laser power

Replace the laser tube

Cleaning uneven

Or when a shallow depth

1. Check the lens and the optical path

Clean the lens, adjust Masamitsu road

2. Check the graphics resolution and scanning accuracy

Increase the graphics resolution and scanning accuracy

3. aging laser tube or laser power problem

Replace the laser tube or laser power

Crochet linear wave phenomena have

1. focusing mirror mirror or loosening

Fixed small front, or replacement of the slider

2. mechanical parts or software problem

Repair machinery or graphics section

How to maintains plasma cnc metal cutting machine

1. Properly assembled the torch 
Properly and carefully installed the torch to ensure that all parts fit well and ensure that gas and cooling air circulation. Install all the components on a clean cloth to prevent dirt from sticking to the parts. On the O-ring with appropriate lubricant to the O-ring is lit subject can not pay more. 

2. Consumable parts to be replaced before the full damage(cnc plasma cutting machine)
Do not completely damaged after consuming parts replacement, because of severe wear electrodes, nozzles and vortex rings will produce plasma arc can not be controlled easily cause serious damage to the torch. So when first discovered cutting quality drops, it should be checked in consumables. 

3. Cleaning torch threaded connection 
When replacing consumables or routine maintenance checks, we must ensure that the torch, external thread clean and, if necessary, should be cleaned or repaired connecting thread. 

4. Clean the electrode and nozzle contact surface 
In many of the torch, the contact surface of the nozzle and the contact surface of the electrode is charged, if the contact surface dirt, the torch is not working properly, you should use hydrogen peroxide cleaning agent class. 

5. Check the gas and cooling gas per day 
Check the gas and cooling air flow and pressure of daily flow is not sufficient or if you find a leak, immediately stop the discharge failure. 

6. Avoid cutting torch collision damage 
To avoid collision damage the torch, the system should be properly programmed to avoid overrun walking mounting protection device can effectively avoid the collision damage the torch. 

7. The most common causes of damage torch 
(1) torch collision. 
(2) consumable parts due to damage caused by devastating plasma arc. 
(3) other dirt caused by destructive plasma arc. 
(4) loose parts and other destructive caused by the plasma arc. 

8. Precautions 
(1) Do not apply grease on the torch. 
(2) Do not overuse O-ring lubricant. 
(3) also remain in the protective cover on the torch when not splash spray chemicals. 
(4) Do not take a hammer to use when manually torch

How to choose stone engraving cnc router machine-EAAK

Choose stone engraving machine in stone engraving machinery industry is particularly important, how to select their own stone carving machine, as follows:
1 Note that the function of the marble engraving machine, granite engraving machine engraving motors with high-power and low-power points. Some cnc engraving machine is only suitable for the processing power of a smaller color plates, architectural models, small signs, three-dimensional crafts and other materials, this process has been popular for some time, but because the power is too small to significantly affect carved its scope of application. Another high-power engraving head engraving machine, engraving machine which has divided into two categories, one is the large format cnc cutting machine: format is generally more than one meter, but the accuracy of this stone carving machine is generally poor; another class is moderate format engraving machine: this machine is generally used in fine carving and processing organic label production.
2 To understand the performance and functionality of carving motors, motor cnc carving machinery engraving head is very critical because the head motor is working long hours, so if carved head motor will not affect the use of engraving machine.
3 adjustable speed range of the motor engraving head, adjustable speed range is generally a few thousand to thirty thousand revolutions per minute, if the speed is not adjustable or adjustable speed range is small, then it shows the engraving machine would be greatly Applications restrictions, because of the different materials must be engraved with a different engraving head speed.
4 Granite cnc router body manufacturing process: the work requirements of high-power engraving machine when the body must be precise and stable, so the long-term power carving casting body should be used in order to ensure its precision and stability.
5 controller is generally divided into two categories: just do the drive controller, and all of its operational work done by the computer, when working at a computer engraving machine in a wait state, unable to typesetting. Another controller when using SBC or MCU control, this controller is actually a computer, so long as the engraving machine start working, the computer can immediately carry out other typesetting work, especially longer sculpture, the advantage is particularly evident.
Important part of the 6 screw and guide rail is also engraving cnc router machine, good screw and guide rail is to ensure its accuracy and performance of the engraving machine used for a long time.
