Hi Manish - On the machine in the video the part moves as the bed of the machine moves in x and y directions - this is by ball screws and encoders - Regards Paul

Hi Machines range in cost from $20k for a basic manual model, approx $40k for one like the video, I believe the best to be Ocean River machines, we have just bought one of these to add to our capacity and its excellent

I guess this is a rhetorical question

Hi Khaled Realistically about 0.25mm depending on thickness - if say 5mm thick between 0.28 and 0.30 - otherwise you need Micro EDM to det smaller

The upper and lower head get programmed separately - ie U and V.

Hi We dont sell them but use them, you can find sellers via search engines Glad you like it though

From were r u

I am not sure where you might get such electrodes - with EDM hole drilling there must be one or more holes through the length of the electrode to enable flushing with high pressure deionised water or dielectric oil. Have you tried looking for 0.4mm diameter brass wire www.amazon.co.uk/Unplated-Brass-wire-0-4mm-26ga/dp/B00JYIH7RI ?

Not a dumb question. It helps ensure even wear on the electrode so the hole does not veer off in any direction

You need a spark erosion machine for a notch - not quite the same machine but similar science....

Not sure what you are getting at - are you thinking of making the electrodes out of spark plug material?

@@edmprecision Yes. If I could find a source for that material, They are made to spark for long periods of time. I wonder, would it last longer than other materials?

@@TheRainHarvester You would need to source Iridium or platinum and would need to be able to buy it in often fairly sizable pieces and machine it easily into the shape required. This is unfortunately not economic and is why Graphite, Copper and Copper Tungsten are used instead. To machine a new electrode in these materials to replace a worn one is cheaper than considering spark plug material

@@edmprecision It would be interesting to try it: take an old spark plug, mount it in the machine, use it to surface down a sheet of material down, and observe the wear.

@@TheRainHarvester If you send me a piece of platinum or iridium I would be happy to try it out - Kind Regards paul - [email protected]

We use generally deionized water. Readily available and easy to generate on site either by reverse osmosis (EASY RO) or by deionizing resins. (we use both). If you want to know more contact me [email protected].

Alex You do get wear on the electrode but unless the material has a very high melting point (tungsten, moly etc) the wear is not too bad.

Hi Pawan If you do not have a user manual or cannot get one I can only suggest you should get yourself a book on spark eroding - there are several on the market. Electrical Discharge Machining Book in google Otherwise download a user manual for another machine as the principles are always the same. Best of Luck Paul

Me to I need to know how to get finish setting and when I should make rough and finishing?
