SINKER EDM BASIC TERMINOLOGY – PART II – FLUSHING MAR 2018 Blog It’s been said the 3 most critical things about a good sinker EDM burn condition are flushing, flushing, and flushing. This is still true today but modern machines have built in technologies that assist with flushing even when the operator doesn’t think about […]

RAM EDM, otherwise known as “Sinker EDM” or “Plunge EDM” has been around for over fifty years. Though widely used, there are some who are unfamiliar with certain EDM terminology. KEY FACTORS OF SINKER EDM Since Sinker EDM uses electrical energy to remove material, it stands to reason that the make-up of the material will […]

A key area for improvement in EDM operations is the reduction of consumables. New technologies, machine settings and improved material grade limit ram or sinker EDM electrode wear to 0.1% while maintaining productive machining speeds. For wire EDM, new low-consumption technologies reduce the biggest expense—the wire itself—by as much as 50 percent. With all EDM […]

\ November 2017 Blog Karl Schmidt, QMR/SSBB – Quality Manager Graphel Carbon Products This past October, a Japanese company named Kobe Steele was found to be falsifying test records and substituting materials for various genuine metallics used in the transportation industry.  Although rare, this can and does happen in the graphite industry. Graphel Carbon Products […]

Jeff Immelt, previous CEO of manufacturing giant GE recently stated about Artificial Intelligence, “Companies need to become digital to survive – We must turn information into insights and insights into outcomes.” That implies we have something to think about: Manufacturing is changing, which isn’t a bad thing. But technology will become difficult to keep up […]

Quality is the backbone of your business – without it, you wouldn’t have the reputation in the industry as a quality manufacturer. So, once you have your quality standards set, it’s time to expect the same from your suppliers. While quality standards will vary, the importance of quality, especially in manufacturing, is a universal requirement. […]

Your organization spends hours working with suppliers to find the optimal balance of price and material grade. You negotiated, compromised, sent RFQ’s and placed PO’s. In the past, many companies didn’t communicate with their suppliers until the next order or delivery was needed. Not anymore. Surveys tell us that the attitude toward supplier relationships has […]

Robert Fothergill, EDM Applications Specialist with Poco Graphite, recently published an article in Mold Making Technology discussing that understanding all the electrode parameters can improve EDM efficiency. I can’t agree more. As discussed, sinker EDM machining technology has improved significantly over the years. These changes effect the processes and decisions an EDM machinist will face […]
