These solutions apply to all metal cutting series, but the specifics are still subject to actual conditions.
No. | Faults | Reasons | Solution | |
1 | There are burning spots on the lower surface of the lower protective mirror | 1.1 | Impure cutting gas | Need to check whether the gas pipeline is clean or replace the gas |
1.2 | Irregular replacement of protective lenses | Operate strictly in accordance with the specifications | ||
1.3 | Worn or damaged seal ring and shrapnel of gas circuit joint | Regularly check the air tightness | ||
The protective window is worn or damaged | Regularly check the sealing of the protection window | |||
Airway blocked | Check whether there are foreign objects in the gas path and clean up in time | |||
1.4 | Improper adjustment of cutting parameters and anti-slag | Properly adjust process parameters, especially perforation parameters | ||
1.5 | Laser head is not up to standard | Replace accessories in time | ||
2 | There are burning spots on the upper surface of the collimating protective mirror | 2.1 | Improper operation of plugging and unplugging the fiber, causing the QBH end crystal to be contaminated | Follow the standard operation, insert the fiber horizontally |
Particle contamination caused by wear when plugging and unplugging optical fibers | Insert and pull out the optical fiber quickly to avoid dust particles; after pulling out the optical fiber, check whether the collimating lens of the laser head is clean | |||
The upper protective lens was contaminated during replacement | Check the sealing condition, and clean the area around the laser head before inserting or removing the protective lens | |||
2.2 | The QBH end and the laser head are not well sealed | Operate in accordance with the specifications, pay attention to the sealing of the connection between QBH and the laser head. After installing the laser head, seal the connection with masking paper | ||
2.3 | QBH end is contaminated | Before inserting the fiber, pay attention to whether the QBH end is contaminated | ||
2.4 | Loose fiber | Re-lock the fiber | ||
3 | Light deviation | 3.1 | Loose adjustment screw | Re-center and tighten the screws |
3.2 | Loose nozzle or ceramic ring | Re-lock the nozzle or ceramic ring | ||
3.3 | Fiber is loose | Re-lock the fiber | ||
3.4 | Laser head quality problem | Replace the laser head | ||
4 | The nozzle over temperature | 4.1 | The focus or collimator is contaminated | Clean or replace lenses in time |
QBH end is contaminated | Check whether the QBH end crystal is contaminated before inserting the fiber | |||
4.2 | Protect the lens from contamination | Clean the fine film according to the specification, and do not blow with the mouth | ||
4.3 | Light deviation | Adjust the optical path centering | ||
4.4 | Wrong cutting focus setting | Refocus | ||
4.5 | Airway problem | Check whether the air path is blocked and clean it up in time; or increase side blowing | ||
5 | Can not cut through, edges have slags | 5.1 | Protect the lens from damage | Replace the protective lens |
5.2 | Unreasonable focus setting | Reset the focus according to the material and its thickness | ||
5.3 | Unreasonable air pressure setting | Reset the cutting pressure according to the material and its thickness | ||
5.4 | Fast cutting speed | Reset the cutting speed according to the form of dregs | ||
5.5 | Nozzle or ceramic body is not locked | Need to lock the nozzle or ceramic body | ||
5.6 | Tracheal leak | Eliminate air leaks | ||
5.7 | Lens condensation | Reset the appropriate water chiller temperature | ||
The protective window is damaged, causing dust to enter | Regularly check the tightness of the protection window | |||
5.8 | Laser head quality is not up to standard | Replace the laser head | ||
6 | One side of Cutting kerf has slags | 6.1 | Light deviation | Adjust light polarization |
6.2 | he nozzle is damaged | Nozzle diameter is not round | ||
6.3 | Laser head is not vertical | Adjust the vertical of the laser head | ||
7 | Cutting kerf is extremely unvertical | 7.1 | Laser head is not vertical | Adjust the vertical of the laser head |
8 | Whole laser head is over temperature | 8.1 | High setting temperature of water chiller | Lower the set temperature of the water chiller |
8.2 | The lens is contaminated | Replace with new lenses | ||
8.3 | Waterway is blocked | Check the waterway or replace distilled water or purified water | ||
9 | Follow-up is abnormal | 9.1 | Nozzle and ceramic ring are loose | Re-lock or replace the nozzle ceramic ring |
9.2 | The sheet is shaking or too close to the edge | Change to a place where the board is stable | ||
9.3 | The RF line and amplifier signal line are in poor contact or the probe is damaged | Replace the RF cable and signal cable | ||
9.4 | The amplifier is damaged | Replace the amplifier | ||
10 | Interlock alarm | 10.1 | Fiber installation is not in place | Check and reinstall the lock |
10.2 | QBH over temperature | Check the waterway | ||
10.3 | Internal contact problem | Check if it is installed correctly |
