Capabilities of Wire EDM: Part 2

Carl Sommer, president of Reliable EDM, demonstrates the unique capabilities of wire EDM. At his company they can wire EDM parts up to 62 inches tall and weighing 10,000 pounds. Sommer shows various tall parts that have been EDM with their modified machines, production EDM, burr free machining, single hole cavity, and the amazing accuracy of wire EDM.
Wire Electrical Discharge Machining has revolutionized machining. Things that were once impossible to machine are now being done with wire EDM. With wire EDM we can cut any conceivable shape up to 45 degrees taper with accuracies of +/-.0001".
Any electrically conductive material can be machined with EDM, even tungsten carbide. An added benefit of wire EDM is that exotic alloys can be machined just as easily as mild steel. Since the wire electrode never comes into contact with the metal, wire EDM is a stress-free machining process.
Sommer, is the president of the largest EDM job shop in North America. He has also co-authored with his son Steve, a mechanical engineer, Complete EDM Handbook. The handbook is free at their website.

Awsome the accuracy is astounding ! I have a small very accurate german made cnc/mill but EDM is levels above a standard CnC . I wonder if it would ever be possible to have a small EDM Machine that would be affordable to the hobbyist ,home machinist and small business one day .

Very impressive, thank you for sharing your knowledge sir.

Could you use the taper cut feature to cut a knife blade? I mean one that is sharp with a very fine edge? And, does Wire EDM disrupt a steel's temper? Either way, you could make some very sharp knives out of some very hard materials.

Thank you

Wire edm burns cutting surfaces and left there heat expansion and reduction cracks on cutted surface metalurgical structure, you can reduce these with fine sparking and use of materials like sleipner tool steel specially produced to reduce micro cracking in the surface, best stamps produce by profile grinding their surface to become more resistant to metal fatique, edm left micro cracks on the surface that leads tendency for fatique cracks occur faster
