Very crisp edges. I learn a lot from your videos. Thanks for making them and sharing them.

Hello, here from Stefan's channel. Super interested, I have a rough idea how this works, so only like 840,302 questions about this. Some explanation would be nice.

Psssst. Stefan sent me. You got cool stuff, I'm now subscribed.

[@rallymax2]

Here from Stefan too. Drop the music and do a voiceover of what’s happening and you’ll be a hit.

Stefan sent me, subscribed. Hope to see much more in the future! Totally fascinating!

[@mith5168]

Stefan sent me… Well Done!

Today’s technology is amazing.

All the CX guys will be happy.

Also here from Stefans channel. I have 0 experience with wire EDM, very interesting! I am an engineer and have a small toolmaking type shop. Back in the late 1980:s I worked with developing a graphite electrode sinker EDM method for the Nobel Pharma Procera titanium implants. We wrote software to compensate the electrodes and used a Chamilles unit. More than one electrode was needed to get to tolerances. Wire edm seems a much better more developed process. Will watch Your work with great interest, subscribed to Your channel. I also suggest You please drop the music and do a voice over.

Stefan sent me! Excellent work!

[@ChevySampath]

Awesome!

[@pirminkogleck4056]

is this the Honda part from gotteswinter ?

[@Tuxbotix]

Looks like that 😃

[@flo_5235]

Yes!

[@robopipiska2988]

Excellent execution!

honda cx500, made in 1978 d still alive.

great work , just drop the music

[@marianbookhahn8561]

Hey Flo, this is very impressive! My Formula Student Team is desperately looking for somebody who can help them manufacturing their planetary gear set for their first electric race car. No manufacturer seems interested in making prototypes.

[@Rickd-jh7iw]

How long is the actual cut time? Would you share how much you would charge for something like this? Thanks

[@flo_5235]

Cut time is under half an hour for this setup.

[@donsundberg5730]

If you end up being small, how do you compensate? Or maybe the better question can you and how do you rework?

[@flo_5235]

G41/G42 with a offset like on a mill or a lathe. So rework is no problem, just change the offset and cut again.

[@donsundberg5730]

@@flo_5235 I was led to believe that wire EDM didn't like taking shallow cuts. Or at least we got a lot of scrap back on parts that didn't have enough stock to remove.

[@flo_5235]

Recut a few microns will not work but if I have to recut maybe 20 30 40 microns this will work. It depends on a few things. Recut a part which is done with only a roughing cut will also not work, if its done with roughing and 1 or more finishing cuts I am able to recut. And you have to be able to measure the part on the machine, most of the time you can´t realign the part good enough for a recut.

[@SamEEE12]

Neat!

[@robopipiska2988]

Please tell me what were the electrical modes (current, frequency) and wire feed speed?

[@Janne1Hirmu]

Horrible music

[@Stoeckermann]

So turn the Volume down, i guess? xD

[@Watchyn_Yarwood]

Try the MUTE button
