Welcome to the first episode of the Everything EDM Learn to Burn series. Zero Tolerance LLC zeroes in on electrical discharge machining (EDM), starting from the basic concepts.

There are many different names for this subtractive manufacturing process: spark machining, spark eroding, die sinking... the list goes on and electrical discharge machining is considered a "non traditional" or "non conventional" machining process. This video, Introduction to Electrical Discharge Machining, will show you how, what, and why.

00:15 Introduction to Zero Tolerance and how they use electrical discharge machining to create their plastic injection molds.
2:14 Beginning the electrical discharge machining process of an intricate mold.
3:37 Using the electrode holder and how it works.
8:43 Continuing the electrical discharge machining process of an intricate mold.
11:24 Quick lesson about how the electrode and voltage create the spark and cut the metal.
13:31 No broken cutters with hardened steel and EDM.
14:01 Thank you and closing
