Electrical Discharge Machine Buying Tips

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.

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?
