During the operation of the Wire Electrical-Discharge Machine, some problems are inevitable. Below are some common questions to answer:
(Note: If the individual still cannot solve the problem after trying, please contact a slow wire repair professional in a timely manner.)
Broken silk
1 Poor discharge state
Solution: Reduce the P value, this operation will reduce the processing efficiency
2 The upper and lower spray nozzles cannot be veneer processed
Solution: Reduce the P value and check if the upper and lower spray nozzles are damaged. If damaged, please replace them in a timely manner
3 The conductive block is severely worn or too dirty
Solution: Clean, rotate or replace the conductive block
4 The wire guide is too dirty, causing scraping
Solution: Clean the wire guide components
5 The machine tension is too high
Solution: During taper cutting, reduce the wire tension appropriately
6 Quality issues with electrode wires and workpiece materials
Solution: Replace the electrode wire; Reduce the P and I values until continuous threading occurs
7 The waste silk in the waste silk bucket overflows and comes into contact with 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 a timely manner
8 Broken wire at the wire receiving wheel
Solution: Check the compression ratio of the wire receiving wheel and check the lower guide wheel bearing
There are silk marks on the surface
1 Deformation of workpiece material or impurities inside
Solution: Reasonably arrange the process or replace the materials
2 The wire guide is too dirty and the conductive block is severely worn
Solution: Timely maintenance and upkeep of the machine tool is required
3 Poor flushing status
Solution: Check the upper and lower spray nozzles. If there is any damage, even replace them with new ones
4 Insufficient cooling water for conductive blocks
Solution: Clean the cooling water circuit
5 Uneven silk transportation and large shaking of the balance wheel
Processing method: Correct wire speed and tension
6 Trimming short circuit rollback
Solution: Adjust and increase UHP
7 There is vibration near the machine tool
Solution: Improve the external environment of the machine tool
8 Excessive liquid temperature or large temperature difference at room temperature
Solution: Use a refrigerator to control the liquid temperature and ensure room temperature
Low processing efficiency
