1) The discharge state is not good
Countermeasure: reduce the P value, this operation will reduce the processing efficiency
2) The upper and lower water nozzles cannot be veneered
Countermeasure: reduce the P value, and check whether the upper and lower water nozzles are damaged, if damaged, please replace it in time
3) The conductive block is severely worn or too dirty
Countermeasure: Clean, rotate or replace the conductive block
4) The guide wire is too dirty, causing the wire to be scraped
Countermeasure: Clean the guide wire parts
5) Too much tension
Countermeasure: Reduce the wire tension, especially when cutting the taper
6) Quality problems of electrode wire and workpiece material
Countermeasures: replace the electrode wire; reduce the P and I values until the wire stops
7) The waste wire in the waste wire barrel overflows and contacts the machine tool or the ground, causing a short circuit
Countermeasure: put the overflowing waste wire back into the waste wire bucket and clean up the waste wire bucket in time
8) Insufficient cooling water for conductive block
Countermeasure: Clean the cooling water circuit
9) The wire is pulled and broken, and it is broken at the wire take-up wheel
Countermeasure: Check the wire pressing ratio of the wire take-up wheel, the standard value is 1:1.5~1.6; check the bearing of the lower guide wheel
10) The wire is not running smoothly, and the balance wheel shakes greatly
Countermeasure: Correct wire speed, tension
1) Not veneer processing, reducing P and I values
Countermeasure: Adjust the Z axis and try to veneer processing
2) The process sequence file is incorrect
Countermeasure: According to the processing requirements, select a reasonable process sequence file
3) The workpiece is deformed, and the trimming does not move
Countermeasures: Reasonably arrange the process to reduce material deformation
4) ACO adaptive function is selected
Countermeasure: When the cutting state is stable, ACO can be cancelled
5) There are many corners, and the corner strategy is used
Countermeasure: Appropriately reduce the corner strategy
6) Repair the mold, the main cutting speed is not limited, and the repair speed is slow
Countermeasure: When repairing the mold, set a reasonable speed limit value for the main cutting to avoid the speed is too fast and the margin is not cut in place
7) The main cutting efficiency is lower than before
Countermeasure: Maintain and maintain the machine in time
1) The workpiece material is deformed, or there are impurities inside
Countermeasure: Arrange the process reasonably, or replace the material
2) The guide wire is too dirty, and the conductive block is seriously worn
Countermeasure: Maintain and maintain the machine in time
3) The flushing state is not good
Countermeasure: Check the upper and lower water nozzles, if there is any damage, even replace the new water nozzles
4) The working fluid is too dirty
Countermeasures: clean the tank and water tank, replace the working fluid
5) Insufficient cooling water for conductive block
Countermeasure: Clean the cooling water circuit
6) The wire is not running smoothly, and the balance wheel shakes greatly
Countermeasure: Correct wire speed, tension
7) Trim short-circuit fallback
Countermeasure: Adjust and increase UHP
8) Vibration near the machine
Countermeasure: Improve the external environment of the machine tool
9) The liquid temperature is too high or the temperature difference between room temperature is large
Countermeasure: Use a refrigerator to control the liquid temperature and ensure room temperature
1) The center of the workpiece is concave
Countermeasure: reduce the Ssoll value of the main cutting and trimming parameters
2) The belly is bulging in the middle of the workpiece
Countermeasure: Increase the Ssoll value of the main cutting and trimming parameters
3) Straight body workpiece size head
Method 1: Add taper compensation
Method 2: Adjust CCON (based on the main program plane J, adjust the size of the reference plane)
Method 1: Use the arc cut-in-arc cut-out method
Method 2: Use the cut-in-cut-out point separation method. When programming, set each feed point at a different position to avoid feeding and retracting from the same point
Method 1: Reduce the electrode wire tension and flushing pressure 2. After normal discharge, gradually change back to the original parameters
Method 2: Move the XY axis to the non-short-circuit position, input CTA, P, X_, Y_ (the coordinates of the short-circuit point), execute the key to discharge manually, and return to the pause point to re-execute the discharge machining
