Fast Hole and Wire EDM | Learn to Burn

Zero Tolerance LLC shows how to harness the power of fast whole and wire EDM to solve a problem in their molding department.
Fast hole and wire EDM are two powerful tools often used in the EDM department. Fast hole is typically used to machine extremely precise holes in the mold block while wire EDM is used to machine features on parts or molds that require extremely tight tolerances.
In this video, Steve Michon from Zero Tolerance LLC, shows how they cleverly used fast hole and wire EDM to machine holes and pins designed to hold aluminum parts in a mold block.

Thanks. I am a 70 yr old self taught manual machinist in Land Down Under. Know nothing about EDM and will never have, or want, the EDM equipment. However, really good to learn the capabilities of EDM if someone ever brings something to me which is outside my current sphere of knowledge. I am a supposedly retired self taught machinist, self taught mechanic, self taught welder etc. So this sort of education is a real bonus to me. Please keep it up the educational videos. Will look at older videos to see what else I can learn. Have a 660mm x 2500mm Taiwanese copy of a Victor lathe, a Bridgeport copy mill and a Pacific universal mill with NT40 taper, plus a tool and cutter grinder which I know little about and have used on few occasions, but am learning. I am very lucky with the home 16m x 8m hobby workshop that I enjoy.

[@puiaturuburu906]

Me too, self taught mechanic, self taught welder, driver, motorcyclist, painter, barber and self taught electrician. You are lucky enough to be able to manage those equipments. I have arc welding machine, hand drill and a hand grinder, that's all i got. Still hoping to learn more in near future. I'm 31.

🤣🤣🤣 You're crazy dude🤣🤣🤣🤣I think I will be better here without trying

[@sikz3506]

I love to see the EDM content. I have been running EDM's for almost 20 years. Mainly high speed hole drilling on Current EDM's and most recently Belmont. Sodick sinkers and Fanuc wires, and after all that experience seeing someone else do it, you can always learn something new! Thank you!

[@thomasbarlow4223]

Super crazy how you can watch a video like this for years because you're just interested in it and then one day your researching it again because you're developing your own product

[@sikz3506]

Must add that your pm's are impeccable! Most of my wires won't self thread any longer!

[@jozefdzugan1828]

Thanks Steve for great content.. looking forward for next episodes !

Thank you Jozef!

Working on getting my budget edm machine up and running which should be by the end of this week getting excited watching people apply it in machine shops

Thank you very much! You are the best!

[@saulpadilla1331]

Great video! I am running a Makino U6 extreme which uses .016" wire. I hope in future videos you can go over the different parameters and settings for different materials and thickness.

[@zerotolerancecnc]

Thanks for watching! We're always looking for topic recommendations, our next episode will talk a little more about machine settings for copper, graphite & copper tungsten and we plan to get a little more technical on the differences in results.

Holycrap that is so cool its a manual machine...... its like a Futuristic Milling Machine

Pretty sure 0.001" dia wire machines exist now as well. Ran ram edm for a few years in a die shop. Cool stuff.

[@Borntobife]

Hi, Thanks for the information. Could you expand please the differences in wire material, I've seen some machines uses molybdenum wire instead of brass.

[@fuego173]

Hello, I have problems threading from a height of 10" inches. The machine is a Mitsubishi MV2400 R. Can you help me? I already calibrated the brass thread with its alignment device but nothing.

Hello. What is the accuracy of this machine (edm drill)? Are the holes tapered?

[@wesleymiller9453]

Hi, I recently acquired the guts of a pulse edm machine- all the electronics, so I built the rest of it up as a “fast hole” sinker. I have attempted to drill a 1/16” hole though a piece of carbon steel about 4 inches long and have spent well over 6 hours only getting to a depth of about 5mm. not to mention this burned up a solid 6 inches of the copper electrode I was using. There is a hole for flushing through the center but I’m at a loss here. any thoughts or suggestions would be appreciated!

[@geoffcharbeneau9573]

How did you pick up the block in the wire EDM? Did you use one of the fast holes for location? Or did you pick up the block on 3 sides and work from the edge?

[@zerotolerancecnc]

Hey Geoff! We normally pick up off a ground edge on the outside of the block.

[@showkathossain1088]

Niece.

[@JazzLowrider]

Could someone explain how the brass or copper wire cut the hard steel and doesn't melt itself ?

[@nathanleigh4306]

The soft copper or brass electrode doesn’t actually touch the hard steel block so there’s no mechanical force involved. The soft electrode actually “erodes” through the hard material. The process causes many small but powerful electrical arcs to form in the tiny spark gap between the workpiece and electrode. Each of those sparks causes a small crater to be blasted into the workpiece ( and electrode ), many per second, as the wire or tube electrode advances into the work. The purpose of the dielectric water or oil is to provide a stable environment for the discharge to form in the spark gap, and to flush away the material that’s melted in the process. Also keeps the wire from breaking under tension, or the tube from overheating..

[@peterfitzpatrick7032]

​@@nathanleigh4306 thats why it used to be called spark erosion...🤫
