Murali - This is possible some machines are better than others at drilling holes to depth and also some are better at redressing the electrode to help make a flatter bottom hole. However you will not get a very small diameter hole - I would expect 0.4-0.5mm. You should expect to have to do a few test holes in a spare piece of metal (same as test part)
@dsfs17987

I've always wondered why the electrode would not spark sideways to the part, only at the tip, I understand that it is a function of the feed rate, making the clearance at the bottom the smallest gap for the spark to jump and the tip erodes somewhat larger hole than the electrode diameter, thus creating clearance that the spark would have to jump, but since the electrodes aren't perfectly straight and are being rotated (as I could see when the electrode exited the SS part), I'd expect some side sparking/erosion going on, or is there some sort of dielectric coating on the electrode sides?
@edmprecision
@edmprecision 6 жыл бұрын
Note that the clean dielectric (de-ionized water in this case) is being pumped at high pressure through the centre of the tube - this encourages the sparks to be generated in the location required (the end of the electrode). However, there will be some sparking on the side of the tube near the tip and often after machining the electrode can be bullet shaped which demonstrates this. - I would say EDM holes are not perfect but they work well when conventional drilling is not possible

On the part in the video we used brass, when we drill alu we try to use copper tubes as the recast layer is less which makes secondary ops such as wire eroding less troublesome. The holes in the tubes are relevant if you are drilling a through hole or hole to a depth, otherwise its all about good electrical conductivity and dimensional reliability.

Thank you very much for answering, you're a great company. I've been thinking about magnetic filtration. Little research and I found this. "...ability to remove 100%* of ferrous particles including sub-micron particles from the process. Traditional filtration systems typically leave particles smaller than 5-10 microns circulating in fluid causing damage to process equipment and finished products."
@edmprecision
@edmprecision 6 жыл бұрын
If you are only going to machine ferrous metals then magnetic is good but not perfect as the brass or copper tubes also get eroded into the water system, and the magnetic system wont collect these. We erode a wide variety of material and not a lot of ferrous, so we will always have to use traditional filers.

What is the purpose of dielectric fluid
@joshhalton9977
@joshhalton9977 4 жыл бұрын
@@sj1130 the purposeof the DI fluid is to cool the electrode and flush the hole. If the electrode becomes coated with the erroded material it will not be as conductive. It may struggle and/or blow out a side wall and damage the surrounding material. It also acts as a insulator until it atomizes from the heat. Then it acts as a coductor and allows the sparks to jump the "gap" between the electrode and the work piece. Thats what causes the cotrolled and accurate erosion. If the electrode loses flush it will heat up and depending on its size, possibly disintergrate. Normally at my shop we also use other flush lines at the hole entrances to avoid this. We hold hole size tolerances at +/-.001 of an inch with a position tolerance a .010 of an inch through several inches of material.

Electrode is rotating to make sure entire bottom is eroded. Electrode is hollow to push a liquid for cooling, removal of debris, as dielectric and to stiffen the electrode. If the electrode would not rotate it would leave a plug that would stuck in the electrode and would stop liquid from flowinng.

@edmprecision 6 жыл бұрын
Hi - I do not believe that the electrode was bending by gravity - they are not that flimsy when they are of a diameter of 0.7mm or more - probably an optical illusion. We have drilled many holes using the B axis which is available on this machine and the we inspect them they are not curved they do remain straight. However, if we were drilling a deep small diameter hole we would test drill in a piece of similar material as the workpiece and if we found that the hole was not straight - we would look to setting the work piece up at the required angle and drill in Z axis only. Engineering is often about problem solving "Adapt and Overcome"

It would be helpful to state what point (time-wise) in the video you are referring to. I sure do not see any bending (or even see the electrode) as he begins the angled hole in the loose block. Surely it would take an inch or so of unsupported extension, depending on electrode diameter, before any significant bending from gravity would take place, and the electrode guide would almost always be placed much closer than that.
