Can I use graphite or copper-graphite electrode materials to machine tungsten-carbide?

Can I use graphite or copper-graphite electrode materials to machine tungsten-carbide?

Apr 6, 2022 | General, Sinker | 0 comments

While graphite materials can be used to machine carbide materials, it is not the best method. One of the reasons is the extremely high electrode wear rate. Burning with a fine-grain graphite, such as DS4 or POCO-3, will lead to 50-60% electrode wear when used to...
Is there an easy way to test the condition of my sinker dielectric oil?

Is there an easy way to test the condition of my sinker dielectric oil?

Mar 23, 2022 | Elements of EDM, General | 0 comments

Depending on the fluid’s type, make and age, the easiest way to check the condition of your sinker dielectric oil is to ask the fluid manufacturer to perform a dielectric strength test. If you are using a standard petroleum-based di-electric fluid, the oil’s useful...
