Back to Basics (4/6): Sinker EDM Machine Basics

Sinker EDM, also referred to as Ram EDM, uses electrodes machined from graphite or copper to shape the workpiece. Typically found in die/mold component manufacturing, a Sinker EDM raises and lowers (sinks) the electrode along the workpiece. Regardless of the name you...
Back to Basics (3/6): Wire EDM Machine Basics

Back to Basics (3/6): Wire EDM Machine Basics

Wire EDM machines use a small, traveling wire electrode to machine complex shapes, which are always through cavities (the wire must pass completely through the workpiece).  Machines are capable of cutting and re-threading the wire automatically, which greatly...

Back to Basics (2/6): The EDM Machining Spark

When you see an EDM in operation, it can appear that there are hundreds or even thousands of bluish-white sparks simultaneously discharging. But in fact, an EDM creates only one spark at a time. Each spark is precisely generated and controlled by advanced adaptive...

Back to Basics (1/6): EDM Beginnings

The EDM (Electrical Discharge Machining) process utilizes short bursts or pulses of electrical energy to erode and machine conductive materials. The process can be thought of as machining with lightning bolts, called sparks. The number and power of each spark can be...
