What is wire and sinker EDM?
Wire EDM is capable of cutting very hard materials, and it is almost always used to cut all the way through the workpiece (with the length of the exposed wire being greater than the height of the workpiece). This is a major difference between wire EDM and sinker EDM, as sinker EDM is used to make cavities.
What are EDM parts?
Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid.
Can you EDM stainless steel?
Materials used in the EDM process must be electrically conductive such as copper, aluminum, bronze, tungsten, carbon steel, high alloy, Inconel, Hastelloy, medical grade stainless steel or carbon graphite.
What is dielectric fluid in EDM?
The dielectric fluid, or coolant, used in the wire electrical discharge machining (EDM) process, is deionized water. It serves several purposes: It acts as a semiconductor between the energized wire and the workpiece to maintain stable and controlled conditions for ionization in the spark gap.
Can you EDM copper?
To obtain optimum results with copper beryllium, the EDM parameters will require processing adjustments compared to steel. EDM of copper beryllium can usually be done at 80 – 100% of the penetration rate for steel while maintaining a smooth surface and acceptable electrode life.
What is EDM wiring?
Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process where a thin single strand metal wire, along with de-ionised water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks, while preventing rust.
Can you EDM aluminum?
What materials can be cut using EDM wire? Any conductive material such as steel, titanium, aluminium, brass, alloys and superalloys can be cut using the EDM wire method. With its accuracy, the EDM wire cut technique has become a convention cutting method in all industries.
Can you EDM nickel?
Perfection With Required Metals With the wire EDM process, various aerospace materials such as titanium, nickel, aluminum, and other stainless-steel alloys can easily be handled. Other conductive materials such as scandium, Kovar, Inconel, Invar, and niobium can also be processed via wire EDM technologies.
Why kerosene is used in EDM?
In EDM, tool is completely submerged into the Kerosene and that too there is no oxygen available hence the spark cannot sustain. Moreover kerosene is a bad conductor of heat so thats why it is used as a coolent in EDM process.
What is spark gap in EDM?
Electrode gap (spark gap) is the distance between the electrode and the part during the process of EDM. Electro-mechanical or hydraulic systems are used to respond to average gap voltage. To obtain good performance and gap stability a suitable gap should be maintained.
