The process of of wire erosion enables us to cut difficult to machine conductive materials with tremendous accuracy. Parts can be from less than 1mm up to 450mm in thickness and very small from a few grams up to 400kg in weight. Wire erosion can cut tungsten carbide, exotic steel alloys, titanium and aluminium – in fact as long as it conducts electricity it can be cut with Wire EDM.
We supply precision EDM machining alongside advanced traditional machining such as large 2-5 axis machining & multi-task mill-turn machining. We also continue to innovate and inspire advanced precision machining, making investments into spark EDM machining technology, among other commitments to innovation.
THE PROCESS SELCTION OF ELECTRODE:
Metal Removal Rate.
Resistance to Wear
Raw Material Costs
Electrode Selection (Spark Erosion)
Electrode material, electrode design and electrode manufacture are three of the many factors to consider in spark EDM. While users of wire erosion machines do have a selection process to consider, design and manufacture of the electrode are not involved as the wire is bought-out and is wound on spools and designed to be expendable. The spark EROSION operator faces quite the opposite challenge. He must select the proper electrode material, then design around flushing and finally ensure that the electrode can be economically manufactured. Then, when sparking the operator must strive to protect the electrode from excessive wear, while maintaining an efficient metal removal rate.
The three most popular types of electrode materials are brass, copper and graphite. Each material has its own unique properties and will fit certain applications better than others.
