What is Electrical Discharge Machining?

A non-traditional manufacturing process uses thermal energy to make something. That goes against what is called mechanical force. EDM, such as CNC Machining Services Sydney, CNC milling, and turning, cannot produce the desired cut, such as when there are sharp internal corners or a particularly deep cavity.

Sink EDM or RAM EDM is an attractive option when complex cavities need to be processed. First of all, a graphite electrode is manufactured in the reverse form to the cavity required to form the die. The process causes a voltage between the die and the workpiece when it is immersed in CNC Routing Sydney a fluid.

The die is slowly lowered into the machine until there is a power failure and a spark. This evaporates or melts the material, and the dielectric fluid extracts the expelled particles. A series of high-frequency sparks are used to trim the desired shape from the material.

Wire EDM, also called wire erosion, is commonly used to make extrusion tools. It cuts with the same mechanism as the descent, but the die is replaced by a very thin electrically charged cable. This processing method is similar to a cheese slicer that performs a two-dimensional cut into a three-dimensional part Machining Services Sydney.

The cutting cable burns during the machining process so that the new cable is continuously replaced by an automated reel to ensure precise cutting. The cable diameter is usually between 0.05 mm and 0.35 mm.

As the name implies, an EDM drilling machine is used to process holes. However, compared to traditional methods of drilling holes, this technique can accurately process extremely small and deep holes that do not require deburring.

This method also uses the same basic principles as sinking EDM, although cutting is done with a pulsating cylindrical electrode that moves deeper into the workpiece when the material is removed. This method was the key to the further development of high-temperature curtain blades, as Metal Engineering Sydney very complicated cooling channels can be produced within the turbine blades. 

One of the main advantages of electric shock machining is that you can cut shapes and depths that would be impossible with traditional machining methods.

This includes features such as undercut and perfectly square inner corners, making it an ideal way to produce an inner corner during CNC machining. The machining process does not create burrs, which is an additional advantage. 

Traditional material removal processes, such as CNC milling, leave marks on the workpiece that require further processing to remove. EDM has zero direction capability for surface quality and allows even smooth surfaces without additional treatment. However, the fast EDM processing can leave a light texture with beads.

Electric shock machining is a great way to use in conjunction with a traditional machining process, such as CNC machining, when parts have specific geometric requirements. In addition, the process’s ability to process hard materials makes it an attractive option when working with materials such as Inconel. However, the machining process is quite slow, so high-volume tasks are not suitable for this method.
