EDM Primer

From R.S. Precision Industries, Inc.
 

 

EDM was originally developed in Russia in the 1950's by researchers who were studying how to reduce the pitting and wear of contacts on electrical relays. EDM soon developed into a viable and original new metal cutting process with many unique properties. R.S. Precision bought their first EDM machine in 1960.

The first EDM machines developed were the Sinker type, then CNC Sinker and CNC Wire EDM Machines were created. There have been tremendous improvements in performance and capabilities for all types of EDM machines over the years, so that while EDM was once used exclusively for Tool and Die work, it has now become an indispensable part of modern manufacturing.
