Quality is Key: Drilling Electrodes and the EDM Drilling Process
Physical variables of EDM drilling electrodes (fast hole tubes) can have a significant impact on process and performance. Oftentimes, these are only discovered when it’s too late, i.e., during machine operation. But it is critical for a successful EDM Drilling operation to understand these variables, how they impact results and quality and how to address them before they become an issue....
