Electrical Discharge Machining in Seregno for the Mechanical Industry

There Effepi Brocciatura Srl, in addition to the shaping and broaching processes, also offers the processing of electrical discharge machining in SeregnoThis technology allows for highly precise and complex machining of hard materials, which would be difficult to achieve with traditional methods.

In practice, electrical discharge machining uses a process of controlled electrical discharges to erode the material, allowing for very accurate shapes and details, even on pieces with complex geometries or made of particularly hard materials.

Electro-erosion consists of cut with a brass wire (called electrode) from 0.25 mm a defined outline, so as to obtain shapes even of very small dimensions, thanks to precise cuts to the centIt is a technique that ensures a lot of flexibility, thanks to the possibility of make even very complex pieces and of perfectly shape all types of metal, very hard and heat treated.

Below are the steps in the process of electrical discharge machiningperformed by Effepi Broaching in Seregno:

• reaching a certain voltage and consequent release of electrons from the cathode
• collision of electrons with atoms and molecules of the fluid, resulting in the creation of positive and negative ions (chain effect)
• complete ionization of the fluid and transformation into a conductor that allows the passage of current
• fluid in the plasma state that causes the melting and vaporization of some areas (both of the piece and the tool)
• voltage which, following the discharge, drops until it is completely eliminated (discharged capacitors)
• resumption of energy accumulation by the capacitors until a voltage is reached that triggers the process again
