CHOSING EDM DRILL ELECTRODES
At Novick, we believe in trust and collaboration when dealing with our customers. Collaboration includes the responsibility to keep our customers well informed, as a customer that knows the strengths and weaknesses of their electrodes stands to gain time and money. There are many different applications that call for EDM Small hole drilling, and one electrode’s weakness in one application may be a strength in another. This and all of the other different variables encountered in EDM—such as workpiece material and machine settings—can make it difficult to choose the right electrode.
With the wide array of electrodes available on the market, you will be sure to find one that fits your particular EDM machine or equipment. EDM drill Electrodes doing well on your small hole EDM machine depend on two simple variables:
- The type of material that the electrode is made of—brass, copper, or tungsten carbide.
- The type of flushing hole or the desired internal diameter of the electrode. This is either a single hole diameter with no other internal walls or is a multi-channel type internal hole with multiple walls throughout the length of the electrode. Some electrodes dispense with the internal channels altogether. These are rods.
- Let’s first discuss the main two types of EDM tubing material: brass and copper. 97% of all applications for EDM electrode hole-popping involve either brass or copper electrodes.
