Wire EDM: How Much Better Is Bigger?

Wire EDM: How Much Better Is Bigger?

Large-diameter wire for EDM has been around for decades, but just recently it has taken the market by storm. To understand how and why this is happening I will go back to my personal experiences as a WEDM operator. In 1976, the industry-standard wire diameter was...
Wire EDM: Common Causes of Wire Breakage

Wire EDM: Common Causes of Wire Breakage

Much research has been done on the issue of wire breakage during the machining process. But before we explore the types of wire that can be used to decrease wire breakage in certain materials, we must first look at what causes wire breakage in general. Current Density...

Wire EDM: Top Ten Cleaning Tips

Wire Spool Area: The interval of cleaning and maintenance in the wire spool area is easier to remember as you replace empty wire spools frequently. A light blast of air or wiping with a cloth is sufficient for general maintenance in this area. Be sure to remove excess...
Wire EDM: Key Physical Properties

Wire EDM: Key Physical Properties

Key physical properties that electrical discharge machine wires must incorporate are: Conductivity: A high and good conductivity rating is imperative in light of the fact that, at any rate hypothetically, it implies wire may convey additional current, that compares to...
Wire EDM: Transport Systems

Wire EDM: Transport Systems

To understand the need for controlling the wire from the spool to the scrap bin or scrap roll, we look at each component and its importance in the wire EDM transport system. We’ll look at where we started and then where we are today.  At the heart of this system...
