The Most Effective Methods for Holding and Retaining Slugs
There are several different techniques for holding and retaining material slugs. These methods will vary based upon the material type and size of the slug. It is important to have a slug management plan in place before machining begins, as it is imperative to prevent...
Back to Basics (6/6): EDM Metallurgical Characteristics
All EDM machining is a thermal/heat process that can alter or change the structure of the machined workpiece. Early EDM technology thermally damaged materials as a result of not controlling the discharge spark energy precisely enough. The resulting metallurgical...
Back to Basics (5/6): EDM Drilling Machine Basics
As highlighted in the first lesson, there are three main types of EDM machines: Wire EDM, Sinker EDM, and EDM Drilling. In this segment, we’ll focus our attention on EDM Drilling. EDM Drilling Machine Basics EDM Drilling machines, which are commonly referred to...
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...
