Common problems and solutions during slow wire running
Time:2023-03-16 Hits:2374
Broken filament
1 . Poor discharge state
——Treatment method: reduce the P value. This operation will reduce the processing efficiency.
2 . The upper and lower spray nozzles cannot be faced
——Treatment method: Reduce the P value, and check whether the upper and lower spray nozzles are damaged. If damaged, please replace them in a timely manner.
3 . The conductive block is seriously worn or too dirty
——Treatment method: clean, rotate or replace the conductive block.
4 . The wire guide is too dirty, causing wire scraping
——Treatment method: clean the guide wire parts.
5 . The machine tension is too high
——Treatment method: properly reduce the wire tension during taper cutting.
6 . Quality problem of electrode wire and workpiece material
——Treatment method: replace the electrode wire; Reduce the P and I values until the wire is not broken.
7 . The waste wire in the waste wire bucket overflows and contacts the machine tool or the ground, causing a short circuit
——Treatment method: put the spilled waste silk back into the waste silk bucket and clean the waste silk bucket in time.
8 . The broken wire is at the take-up wheel
——Treatment method: check the pressing ratio of the take-up wheel and the lower guide wheel bearing.
There are silk marks on the surface
1 . The workpiece material is deformed or has impurities inside
——Treatment method: reasonably arrange the process or replace the material.
2 . The wire guide is too dirty and the conductive block is seriously worn
——Treatment: The machine tool needs to be maintained in time.
3 . The flushing condition is not good
——Treatment method: check the upper and lower spray nozzles. If there is any damage, even replace them with new ones.
4 . Insufficient cooling water for conductive block
——Treatment method: clean the cooling water circuit
5 . The wire conveying is not smooth, and the balance wheel shakes greatly
——Processing method: correct wire speed and tension
6 . Repair short circuit fallback
——Treatment method: adjust and increase UHP
7 . There is vibration near the machine tool
——Treatment method: improve the external environment of the machine tool
8 . The liquid temperature is too high or the room temperature difference is large
——Treatment method: use a refrigerator to control the liquid temperature and ensure the room temperature
Low processing efficiency
1 . Without veneer processing, P and I values are reduced
——Processing method: adjust the Z axis, and try to face processing
2 . Workpiece deformation, unable to repair
——Treatment method: reasonably arrange the process to reduce material deformation
3 . There are many corners and corner strategy is used
——Treatment method: properly reduce the corner strategy
4 . Mold repair, main cutting without speed limit, slow repair speed
——Treatment method: during mold repair, set a reasonable speed limit value for the main cutting to avoid too fast speed and the allowance is not cut in place.
5 . Main cutting efficiency is lower than before
——Treatment method: timely maintain the machine tool.
