EDM Precision technologies - Spark Erosion

[@stayfrosty1758]

short, simple and comprehensive video made with a gentle and professional tone. So many youtubers should learn from this video!

[@ManuelGutierrez-bo1fb]

A regular machinist could take a lifetime to achieve the accuracy and finished surface using conventional tools and techniques....Marvelous to see this technology applied to plastic injection for Plastic models....Sweet !! Thanks for sharing this...

[@alfredchen4579]

Thank you very much for making this video! It helps quite a lot.

Hello sir Thank you for your video it's helpful But u say that at finish path electrode move orbital is that mean that electrode rotate? In video it's not rotate

Precision engineering is still a surprisingly competitive market. As a result it is difficult to get the true value of the work from customers. If all machine shops charged a bit more then there would be more money available to reward staff.

I’m not sure where you live, but where I live these guys can command like £1k a day

[@chrisfell5109]

Ain't that the truth lol

​@globalgears5175 where do u live, lucky if I get that a week lol

Thank you😊

[@wiraxbox360]

I see the black carbon that prevents follow, if the electrode had small letters the result would be very blurry?

[@MielExpres]

whats the price of this machine or work?

[@cncit]

I'm new to this technology. If you were making a hole to fit a ground dowel pin for locating another fixture to it for example how much undersized would the electrode need to be. Or would you rough it out then use the cnc x and y travels on the machine to form a larger hole.

[@edmprecision]

Your second statement is correct. - An electrode smaller than hole is used , once it has sparked to depth the program would include an "orbital" path moving in both x and y simultaneously with the orbit gradually increasing until the required size is achieved.

[@wealllikeitsomilkit4301]

Ah yes.. spark erosion machine.. I definitely need to learn about this as an english major..

[@shifty5159]

Educational, thank you!

[@satyaprakash-sf1pc]

Thank you ... Its very informative !

[@edmprecision]

Thank you - we have videos on wire erosion and fast hole drilling too www.edmprecision.com

[@GraphicManInnovations]

Great Vid I know that the machined part takes exactly the shape of the electrode within about 2 microns, but how the debris have a chance to come out when using a straight electrode like the one in the video, also with such a small space between the walls of the machined part and the electrode how the fluid comes out?! even without a fluid the air can stop the electrode from getting inside?

[@edmprecision]

Hi The precision you should expect from spark erosion would be under normal conditions +/- 0.010. The gap between the electrode and the work piece is called the spark gap and from this we create the under sizing of the electrode relative to the feature - we would normally go with 0.18/side under sizing this allows good flushing and debris removal during the rough machining to depth. We then orbit the electrode in x and y in a circular, square, hexagonal pattern with progressively lower power until the desired size and finish is achieved (this is the machining strategy). In short greater under sizing of the electrode enables a larger spark gap = bigger spark, faster material removal, but rougher surface finish. If the machine you have can orbit you do not necessarily need one or more finishing electrodes with less under sizing to get great results you may be able to use the same electrode but with smaller finishing sparks as the electrode is orbited closer to the work piece. I hope this answers your question

[@GraphicManInnovations]

Prompt and perfect explanation, thank you very much sir!

[@TheWireEDM]

To add to the great answer from EDM Precision, thhe lectrodes for blind cavities typically have flushing holes drilled in to them. These can be very small, like 0.5 mm, just to let the gases escape (important when the electrode is like an inverted cup) and to provide fresh clean dielectric to the spark gap. Somewhat larger holes are usually done to provide suction, so that the machine sucks the oil and debris through the electrode. In a blind cavity this prevents the side walls from overburning to a tapered shape as the debris is not flowing between the finished sides of the workpiece and electrode, which would otherwise create a shorter spark gap condition and spark through the debris.

[@ecncshop]

What is the typical speed ? How long it took to make that hexagonal cavity of ~20mm or 1" depth in this video ?

[@edmprecision]

Machine speed is very dependant on the surface finish required - fine surface finishes Ra 0.8 or better could take twice as long as Ra 3.2. For a basic Hex in Aluminium as per the video 30 mins. Tip - Ensure you specify only the surface finish that you really need.

[@pawantiwari412]

Please explain finishing setting. I am unable to find finish surface. I reduced current and TOn but did not find desired finish.

[@edmprecision]

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

[@prodengmohamd8238]

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

[@MTmasterMacchine]

Awesome technology. We also show videos of this technology on our channel. it's a fantastic technology !!!👍

[@TheRainHarvester]

Would using spark plug electrodes resist erosion of the tool?

[@edmprecision]

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

[@TheRainHarvester]

@@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?

[@edmprecision]

@@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

[@TheRainHarvester]

@@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.

[@edmprecision]

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

[@manishsharma7645]

How it's work in x and y axis

[@edmprecision]

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

[@e122720]

Why the sparks don't erode the copper electrode?

[@edmprecision]

The electrodes do get worn - but on low melting point materials the wear is low a few % The Generators in the machine can help you protect the electrode - this can slow the machining down so you would tend to only use this if the electrode is tricky (expensive) to make.

[@sunbee5834]

Was that a spark on time or a spark off time?

[@edmprecision]

Hi Sun Video was shot some time ago - I do not recall the specific machine settings. If you email me with specific requirement I will do my best to reply [e-mail] Kind Regards Paul
