Spark erosion is the process of vaporizing metal using a high-frequency spark discharge. Metal disintegrators are a subcategory of EDM, which is often referred to as Spark Erosion. Metal Disintegration Machining (MDM) is the process that Electro Arc machines use. These machines are specifically used to remove broken bolts, taps,…
Your Guide to EDM Terminology
EDM has become a common method used across industries with a number of sub-categories including MDM. This list of EDM terms can help you understand all of the aspects of EDM. Many of these terms are interchangeable with MDM terms: Ammeter (Amp Meter) – A measuring instrument for electrical current. Amp…
Why Do I Need DC Cutting?
D.C. cutting is direct current cutting, which is a naturally occurring process that moves metal from a positive pole (+) to a negative pole (-) when current flow is initiated (switched on) and subsequently interrupted (switched off). You may not know that this process is as old as the storage…
What is the History of Electro Arc and EDM?
When you search for the term “metal disintegrator” you will likely find ‘Electrical discharge machining’ as a result. That is because the technological breakthrough that led to metal disintegrating machines was spearheaded by a team including Harold Stark who went on to patent the idea for AC metal disintegrators and…
