Do you know the common faults and treatment methods of Sodick wire cutting machine?

1. Slow processing speed and disconnection
1. Improper use of processing conditions.
Countermeasures: Modify the processing conditions parameters, weaken the processing conditions and reprocess.
2. Poor water spray
Countermeasure: Check whether the high-pressure water spray is turned on.
3. The opening and closing thread guide is too dirty, and the conductive block wire groove is too deep
Solution: Clean the thread guide, and the conductive block should be displaced.
4 The wire wheel of the lower head does not rotate
Countermeasure: Before processing, check whether the lower wire wheel rotates normally. If it is too dirty, it needs to be cleaned.
5. Poor nozzle gap adjustment
Countermeasures: If the water spray nozzle is attached too close, it will cause short lines, so it should be adjusted to the proper position (normally 0.1mm-0.2mm).
6. The processing speed is slow
Countermeasure: Check whether the conductive wire is broken? Whether the conductive block of the thread guide has quality problems and whether the ion degree is normal.
2. Drum shape
(1) Punch:
1. If the middle is small and the two ends are large, it is because the speed of the second knife is too slow, so the SV value in the C002 condition should be reduced, which should be reduced by 5-10V.
2. If there is a large middle and small ends, it is because the speed of the second knife is too fast, the SV value in the C002 condition should be increased, and the SV value should be decreased by 5-10V.
3. While modifying the SV, you can also increase the WT value by 10, such as changing from 160 to 170.
1. If the middle is small and the two ends are large, it is because the speed of the second knife is too fast, the SV value in the C002 condition should be increased, and 5-10V should be decreased.
2. If the middle is big and the two ends are small, it is because the speed of the second knife is too slow, the SV value in the C002 condition should be reduced, and the SV should be reduced by 5-10V.
3. While modifying the SV, you can also increase the WT value by 10, such as changing from 160 to 170.
3. Line marks
Countermeasures:
1. Check whether the ionization degree of the hydropower and the spraying state are in good condition. Especially the state of low pressure water.
2. Check whether the thread guide is too dirty and whether the tension has changed.
3. Whether the processing conditions and compensation are appropriate.
4. Whether the workpiece is deformed.


Four. C900 conditions can not be repaired
Countermeasure: Check whether the compensation amount of the first and second tools is too large. If it is, the compensation of the first tool should be reduced. Also pay attention to check whether the conductive wire is broken.




Five. Inconsistent upper and lower dimensions
Countermeasures: increase the taper compensation; use an inverted taper for the punch and a forward taper for the concave mold. Usually it is 0.001-0.002 degrees, if 2cut5um processing conditions are used, it should be 0.005 degrees.
