Wire cut edm applications because of its versatility manufacturers use edm wire cutting machine operation for an extensive range of applications.
Wire cut edm applications.
Machining typically creates distortion in the area surrounding the cut.
The wire which is constantly fed from a spool is held between upper and lower diamond guides which is centered in a water nozzle head.
If a small pilot hole is pre drilled into workpiece wire can be threaded through it to complete the operation using wire edm.
Wire edm is most commonly used in mold and die manufacturing processes particularly for extrusion dies and blanking punches.
It can also cut various sample plate magnetic steel silicon steel sheet semi conductive material or precious metal.
In the wire cut edm process water is commonly used as the dielectric fluid.
The guides are usually cnc controlled.
A hole is first drilled through the die blank often also by edm and the wire is then threaded through.
Produce almost any part with a single wire cut cut conductive materials ranging from aluminium and copper to graphite with an electrical spark.
Tooling applications for wire edm probably the best known application is cutting the profile in extrusion dies.
The process is best suited for applications requiring low levels of residual stress.
The principle benefits of edm its excellent surface finish minimal heat affected zone haz and ability to cut hardened materials and exotic alloys make it ideal for certain hole making applications.
For aluminum extrusion these are usually made from h13 tool steel.
Filters and de ionizing units are used for controlling the resistivity and other electrical properties.
Wires made of brass are generally preferred.
Edm technology allows you to achieve extreme accuracy when producing incredibly delicate parts at very high cutting speeds.
Edm can be used in everything from prototypes to full production runs and is most often used to manufacture metal components and tools.
Due to its ability to cut complex shapes without the set up times of conventional processes wire electrical discharge machining wedm lends itself to the prototyping or limited run production of miniature gears with a low aspect ratio for use in small mechanisms.
Because the process can cut very small pieces it is often an ideal choice for the production of small highly detailed items that would normally be too delicate for other machining options.
Wire edm is particularly valuable for its ability to cut a wide range of hard thick thin and fragile materials without compromising the surface or edge of the material.
