01 broken thread
1) Bad discharge status
Counter-measuring: reducing value P, this operation will reduce the effectiveness of treatment
2) The upper and lower spray nozzles cannot be treated in the veneer
Countermeasures: Reduce value P and check if the upper and lower spray nozzles are damaged.
3) The driver’s block is seriously worn or too dirty
Countermeasures: clean, rotate or replace conductive blocks
4) The guidance wire is too dirty, causing the scratch of the wire
Conversely: Clean the parts of the wired guide
5) The tension is too high
Countermeasures: reduce the tension of the wire, especially during the conical cutting
6) Quality problems of the materials of the electrode wire and the part
Countermeasures: replace the electrode wire;
7) The waste wire in the Waste Wire burst overflows, contacts the machine tool or the mass, causing a short circuit
Counter-to effect: Put the thread of waste overflowing in the bucket of waste and clean the bucket of waste wire over time
8) Inadequate cooling water for conductive blocks
Conversely: Clean the cooling water circuit
9) The Silk CourtePointe is broken and broken with the wire collection wheel
Contreheasures: Check the compression ratio of the wire wire wire, the standard value is 1: 1.5 ~ 1.6;
10) The movement of the wire is not stable and the balance wheel shakes considerably
Reversers: Correct wire speed and voltage
02 Low treatment efficiency
1) No veneer treatment, reducing values p and i
Countermex: Adjust the Z axis and try to treat the surface
2) The process sequence file is incorrect
Break up: Choose a reasonable process sequence file according to processing requirements
3) The part is distorted, and it cannot be repaired and cut
Countermeasures: organize the process reasonably to reduce the deformation of materials
4) The ACO adaptive function has been selected
Counter-measuring: when the cutting state is stable, the ACO can be canceled
5) There are a lot of corners and the local strategy is used
Countermeasures: correctly reduce the corners
6) Modification, the main cutting speed is not limited, the speed of punctual repair is slow
Breakdown: When renovating the mold, define a reasonable speed limit value to avoid too fast speed and the margin is not set up.
7) The main cutting efficiency is lower than before
Break up: timely maintenance of machine tools
03 There are silk brands on the surface
1) The material of the part is distorted, or there are impurities inside
Countermeasures: organize the process reasonably or replace the materials
2) The wire guide is too dirty and the driver’s block is seriously worn
Break up: timely maintenance of machine tools
3) The liquid is in poor condition
Conversely: Check the spray nozzles with upper and lower water.
4) The work fluid is too dirty
Countermeasures: Clean the liquid tank and the water tank and replace the work fluid
5) Inadequate cooling water for conductive blocks
Conversely: Clean the cooling water circuit
6) The movement of the wire is not stable and the balance wheel shakes considerably
Reversers: Correct wire speed and voltage
7) Repair and cut a short circuit
Countermeasures: adjust and increase UHP
8) There are vibrations near the machine tool
Countermeasures: Improve the external environment of the tool-tool
9) The temperature of the liquid is too high or the difference in room temperature is large
Countermeasures: use a refrigerator to control the temperature of the liquid and ensure the room temperature
04 Center of room and large head
1) The center of the part of the room
Conversely: the SSOLL value of the main cutting and cutting parameters can be reduced
2) The navel in the middle of the room
Conversely: the SSOLL value of the main cutting and cutting parameters can be increased
3) Size of the size of the right body part
Method 1: Add conical compensation
Method 2: adjust CCC (the surface of the main program J is used as a reference, and the size of the reference surface is adjusted)
05 brands of thread to the insertion of the matrix
Method 1: Use the archery cutting method
Method 2: Use the cutting method of cutting points. When programming, define each power point to a different position to avoid power supply and retraction of the same point
06 Short of threaded hole
Method 1: Reduce the voltage of the electrode wire and the punch pressure 2. After a normal discharge, gradually switch to the original parameters
Method 2: Move the XY axis to the non-circuit position without shorts, enter CTA, P, X_, Y_ (contact details of the short-circuit point) to manually unload the keys, return to the break and reactivate the treatment of dump .
