    Mar 08, 2014· The wire then passes through a set of precision, round diamond guides, and is then transported into a waste bin. The wire can only be used once, due to it being eroded from theEDM process. 20. Most WireEDM’s are equipped with a programmable "Z" axis giving precise control of the upper guide assembly to ensure accurate tapers.

    Introduction to ShotPeeningShotpeeningis a cold workingprocessin which the surface of a part is bombarded with small spherical media called shot. Each piece of shot striking the metal acts as a tinypeeninghammer, imparting a small indentation or dimple on the surface. In order for the dimple to be created, the surface layer of the metal must yield in tension.

  • What isElectrical Discharge Machining(EDM)Processand

    Apr 12, 2017·Electrical Discharge Machining(EDM) is a non traditional machining and electro thermalprocessin which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. InEDMmachine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes.

  • Difference Between EDM and ECM Electro Discharge

    Electro-Discharge Machining (EDM) is one thermal energy basedprocesswhere material is removed by localized melting and vaporization. Intense heat is generated by means of electric sparks. Here the tool made of conductive material is made one electrode (negative polarity), while the conductive workpiece is made another electrode (positive ...
