Electrical Discharge Machine Buying Tips

Electrical Discharge Machine Buying Tips
Electrical Discharge Machining or​ EDM is​ electrical equipment or​ a​ machining method that is​ used for hard metallic materials .​
It is​ primarily used on hard metals that cannot be processed by traditional methods and techniques .​
Electrical Discharge Machining, however, only works with metallic objects that are electrically conductive .​
EDM can cut small unusual shaped angles, complex curves and outlines in​ numerous types of​ extremely hard steels and exotic metals like titanium and carbide just to​ name a​ few.
1 .​
How It Works
Sometime referred to​ as​ spark machining or​ spark eroding .​
Electrical discharge machining is​ a​ method of​ removing material by a​ series of​ rapidly recurring electric discharges between the cutting tool and the work piece, in​ the presence of​ an​ energetic electrical field .​
The EDM equipment is​ guided very close along the desired path but it​ does not touch the metallic piece .​
Instead the sparks produce a​ series of​ micro-crates on the metallic piece and remove materials along the desired path by melting and vaporizing them .​
The wasted particles then are washed away by the continuous flushing of​ dielectric fluid.
2 .​
Choose Your Type Of Machine
First you should specify what kind of​ Electrical Discharge machine you are going to​ utilize for there are two types of​ Electrical discharge machining equipment on the market today .​
The wire and the probe or​ die sinker Electronic Discharge Machine .​
If your company is​ into processing complex geometric shapes then the probe or​ die sinker EDM is​ the tool that you should use and buy .​
This kind of​ Electrical Discharge Machining tool uses a​ machine graphite or​ copper electrode to​ erode the desired shape into the metallic materials .​
Alternatively, if​ your company is​ more into assembly part cutting then the wire EDM is​ the best machining method to​ be used .​
In a​ wire EDM a​ hole must be first drilled into the material then a​ wire will be fed through it​ to​ cut the desired shapes.
3 .​
Scale Of Production
The next thing to​ think about is​ the scale of​ production that your company will be manufacturing .​
If it​ is​ on a​ large scale production then you should think of​ buying bigger Electrical discharge machining Equipments .​
There are selling companies that give out discount if​ you will be purchasing a​ large amount of​ EMD tools .​
Of course, if​ your company is​ into small amounts of​ production and will be utilizing EDM tools on a​ one time usage basis only, then you can just have your metallic pieces cut-out by EDM companies .​
It is​ much cheaper to​ just pay for the service charge than purchasing your own Electrical discharge machining Tools.
4 .​
Ask Yourself:
- What kind of​ products will I​ be producing?
- How many products will I​ be producing?
- Do I​ have the right amount of​ money and resources to​ fabricate this product?
5 .​
Getting The Best Deal
You can find numerous companies that sell different kinds of​ Electrical discharge machining tools on the internet .​
So before going to​ the nearest EDM stores in​ your locality, why not check out the internet first, it​ could save you time, money and the hassle of​ driving out in​ the city .​
And with the tight competition of​ online companies you can even find a​ discounted price for new EDM equipments online .​
There are also e-commerce sites that offer second hand and fully refurbished electrical discharge machining tools on the internet .​
So if​ you are having financial issues but really need to​ buy one, second hand EMD equipment may work fine for you.
