When the CNC DIE sinker is running, normally the electrode consumption is  about one thousandth of the consumption, which is a normal situation. Because all the workpiece is processed by the electrode discharge. If the discharge consumption is too large, an abnormal situation occurs. What are the problems with this abnormal consumption? What are the ways to reduce electrode wear?

We offer three ways to avoid excessive electrode consumption.

copper electrode consumption

1. the sparking oil is not selected correctly.

 Its special EDM oil washing or sub-merge process is a key factor in removing electrical corrosion during operation. If the sparking oil is not selected correctly, it will affect its discharge results. Rapid spindle lifting ratios can significantly improve chip removal efficiency, pulse pause duration and chip removal.

2. CNC DIE SINKER’s short-circuited during operation.

In the operation process, there is a discharge gap between the processed product and the electrode. If there is a secondary discharge, the energy will be lost during heavy melting of the erosion debris. This will reduce the working efficiency of CNC die sinker EDM and burn the working surface. Thus, it will cause the higher electrode consumption ratios.

3. Discharge parameter selection for the sparking process.

When the machine is operating, it is necessary to select appropriate operating parameters to prevent arc discharge and secondary discharge. When encountering relatively large materials, increase the spindle lifting ratio as much as possible.

If the above aspects can be perfected well, the electrode consumption of the electrical discharge machine can be controlled to be less than one thousandth, and the discharge efficiency is high, the products produced are more satisfactory, and edm machine is relatively stable.
