surface grinding copper edm electrodes


Posted on November 21, 2019



Solving The Mystery Of How To How To Grind CopperEven though the vast majority of copper EDM electrodes for injection mold making are machined by CNC machines, knowing how to grind copper is a valuable skill in the surface grinding process. There is always the odd job, or rework that requires manual grinding of copper. One of the main reasons copper is avoided is.surface grinding copper edm electrodes,Don't Read This If You Use Graphite Electrodes For EDMGraphite electrodes for EDM have become the industry standard, with copper and copper tungsten still important. High speed milling machines are standard.
