Wire electrical discharge machining (EDM) is a process of metal machining in which a tool discharges thousands of sparks to a metal workpiece. The flow of high velocity gas into the gap facilitates removal of debris and prevents excessive heating of the tool and work piece at the discharge spots. Mold and part manufacturing-injection nozzles, oil drain holes, hydraulic cylinders and dowel pins, as well as turbine blades, ball bearings and safety wire holes in hex nuts are just some of the. The general principle of electroerosion machining is the following: disruptive discharges are exerted on the workpiece and via an electrode thus the deteriorated particles are cooled and drained through a continuously filtered dielectric liquid. This includes turning and wire EDM machining as well as hydraulic, servo, and mechanical presses, micro spot welding, robotic laser welding, laser cutting and much more. ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). Mold and part manufacturing-injection nozzles, oil drain holes, hydraulic cylinders and dowel pins, as well as turbine blades, ball bearings and safety wire holes in hex nuts are just some of the. 000002 inch and produces systematic dimensional reports on every job. However, instead of wire, EDM hole drilling uses an electrically-charged metallic electrode tool that works much like a traditional drill bit for hole machining. At the heart of this venture is a CNC machining cell that was engineered using lean principles.
