Analysis of wear causes of WEDM conductive blocks during aluminum processing

There is a very troublesome problem, that is, when we use aluminum materials processing, WEDM conductive blocks will be seriously worn, today, we will analyze what causes WEDM conductive block wear, and find ways to improve.yize17ka

According to the analysis of the operators on the spot, the main causes of wear and tear of the WEDM conductive blocks in processing aluminum materials and the solutions are as follows:

1.Setting of pulse parameters
Because in WEDM, a wide pulse width or a small pulse interval will produce a larger alumina particles, and adhere to the electrode wire, thus plugging the gap, resulting in electrode wire fracture. The solution is to increase the value of the impulse voltage, reduce the pulse width and increase the pulse gap.

2.Working fluid requirements
The conventional processing fluid is configured at 1:10, and the configuration of aluminum material is 3:8. Therefore, in order to keep the working fluid clean, it is necessary to keep the working fluid unobstructed and wash the sponge regularly to reduce adhesion.
 
3.Electrode wire jitter

During the machining of high-speed Wire edm wear parts, the electrode wires of high-speed communication constantly shake, resulting in the power supply can not play normally. A sponge can be added to the rear end slot of the wire rack, and the electrode wire will reduce the chattering after being rubbed through the sponge.

The above is the cause and solution of the wear of the WEDM conductive blocks when processing aluminum materials. All experience comes from practice, so if you want to do a good job, you have to work hard and accumulate in your daily work.
