LEADERS IN EDM MECHANICAL MACHINING FOR OVER 30 YEARS
EDM allows us to process every kind of conductive materials, as well as create high precision geometric shapes.
EDM is a metal removal method that uses an electrode tool which is brought close to the workpiece. Material is removed from the workpiece by a series of rapidly recurring current discharges, giving it the desired shape.
Depending on the workpiece material and the geometric shape desired, three kinds of EDM are available:
WIRE EDM
Depending on the material, the wire EDM electrode is made from copper or brass.
DIE SINKING EDM
In die sinking EDM the electrode can be made of copper, copper tungsten or graphite, depending on the desired shape.
MICRO-DRILLING EDM
Micro-drilling EDM uses a rotating tube electrode made of copper or brass, which realises deep holes in conductive metals.
Why choose EDM
- It works hard metals or metals with chemical or thermal treatments, such as tempered steel. It’s mostly used for blanking molds, die casting molds, molds for plastic, molds for rubber as well as extrusion dies for rubber.
- Sharp edges, ribs and holes with cylindrical or conical shapes as well as complex profiles, can be achieved using EDM.
- The erosive action of EDM creates micro-craters which give the desired shape to the workpiece. High geometric tolerances and low surface roughness are feasible with the addition of finishing cycles for die-sink EDM or wire EDM processes.
