I had access to a professional EDM machine in my last job - the potential uses are endless: chisels for the lathe made from hardened HSS blanks takes minutes, high precision parts from titanium w/o the work hardening, thin-walled jewelry from super-alloys, a complex clamping mechanism that withstands high temperatures? That EDM machine saved us so much time and money!

@barrag3463 Месяц назад

Random comment but you should be careful with using superalloys for jewelry; dermatological nickel allergies are a thing and they are not fun. From personal experience even just having Inconel chips on my skin for a couple minutes can cause my skin to get hives.

@f.d.6667 Месяц назад

@@barrag3463You are absolutely correct. Nickel is no joke and we were anal with the alloys we picked for our regular products (professional coffee makers). Some of the stuff we made were display things that only had to survive a photo shooting and were then put in storage. The other thing we found out is that some alloys are pretty "hot" in terms of radiation. Some of our suppliers were pretty careless when smelting scrap metal so we had to check all their shipments with radiation meters...

@arthurmoore9488 Месяц назад

@@jungletek Note that radiation risk is relative, and depends on the type. If it's alpha, then a simple glaze would work. If it's something else, then dose matters. For example, Uranium glass is safe to keep on a shelf and drink from, but probably not the best for jewelry. Course, that doesn't fly for a commercial product without regulatory approval.

@@jungletek China. From what I hear, a lot of the imported leather goods are so radioactive that they get confiscated by customs... there was a wave of cases of radiation sickness in major cities across China last year that can be linked to the burning of contaminated coal from a mine in Northern China. What virtually nobody in the West is aware of, is the fact, that for every kilogram of neodymium (essential for EVs and wind turbines), the same amount of radioactive Uranium and Thorium is dumped in open tailings ponds and then carried as dust across Northern China and India. Cancer rates of 44% are "normal" in the regions where mining/refining of those rare earth elements is taking place...

Its so refreshing to see people so positively "hooked" in the things they do

@kenmagalnik6596 Месяц назад

With professional wire machines, the use cases tend to be: Since there is no tool to part contact, they are incredibly accurate. If something needs to be spot on, wire it. 2. It cuts anything conductive, without care for how hard it is. It will cut hardened steel. 3. It can cut an almost square inside corner (limited by the wire diameter which is very small). These 3 combine to make wire machines the primary method for making stamping tools

@gogota_ Месяц назад

Not even diamater but radius :)

@AllSeeingEy3 Месяц назад

@judlex7300 Месяц назад

What if square wires were made, would that make a perfect inside square corner

@gogota_ Месяц назад

@@judlex7300 That would be sick at one point but there are other options. On corner wire edm stops for short period of time to machine corner. Or you can use smaller diameter of wire to make even smaller radius. For that kind od WEDM we use 0.1mm wire instead of standard 0.25 or 0.3mm 😎

@kenmagalnik6596 Месяц назад

@@judlex7300 almost, but no. You need a bit of space between the wire and the metal you are cutting, for where the spark jumps and where the water washes out the burned metal. It's about half the wire diameter. So with a square wire you'd get a radius of about half the wire diameter rather than the whole diameter. Also, I suspect it won't be an arc, but rather some kind of parabolic who knows what shape. A lot of machines are made to run multiple wire diameters. 0.010 for most cuts, plus .002 for the super fine stuff. But really, .01 inside radius is pretty damn small, and you can usually just deal with that.

List of things to further DIY for EDM: A controller to handle all of the below. Flushing! Pumps, nozzles, variable water pressure, high and low flushing conditions. Deionizing filter, industry standard is glass beads in a bottle that can be recharged. Water resistivity sense, so that the DI filter doesn't make the water too clean. Water level sense, so the work tank can cycle water by itself. Paper filters, to clean out the larger chips. Wire sensor touch, auto wire threading, and water chilling are probably out of reach. Not a bad deal if you can't buy something like the Sodick VN400Q.

@SolarMillUSA Месяц назад

Water chilling doesn’t sound too unapproachable. You can get refrigerated units for laser cutters and Tig welders for relatively cheap. If for some reason the metallic sides and parts too many ions into the water, then I could imagine an open source solution with a plastic coil submerged in a refrigerated heat exchange fluid being a good community project.

@26:50 I have a bunch of hobbies, including the fiber arts, and this happens all the time with yarn, too. You always have to look at the dye lots on the yarn labels, to see which were dyed together, and therefore have the same color. If you get yarn that looks identical, but has different dye lots, and then knit with one for half a sweater, and with another for the other half, you'll most likely see it. It'll look like half the sweater was left out in the sun for years and faded a bit. You can get around it pretty well by alternating skeins every row. That's a bit harder with 3D printers.

If you're going to EDM within a magnetic field, be prepared for some interesting movements of your wire due to Lorentz forces.

The best tool/machine isn't the one that's the best, it's the one you can have/afford/manage. I develop software for industrial extruders: to give you an idea, during processing they use tens of kg of plastic per minute, the feed screw alone weighs 20 tons and they have tanks of 1 or 2 tons of pellets. They are certainly better and faster than our 3D printers: but if you don't have several millions, a warehouse, 4 or 5 operators etc. you can't have or use it. Same thing for CNC: I modified an Ender 5 Pro and a Plus to also use a spindle. In aluminum I can only do 0.16/0.2 DOC: slow but better than nothing. Next thing: EDM for sure.

It feels too bad to just throw plastic out like that when it's only been used once and I know the exact material, so I've been kind of... holding out for a way to affordably recycle it, and only printing things with immediate practical uses in the meantime. If you have a 3D printer with constant, closed-loop filament diameter sensing (shouldn't be too hard? Technically you want the cross-sectional area [or in-nozzle pressure?], not just the diameter, since it could be out-of-round, is this really that bad?), you could use fairly inaccurate home-extruded filament effectively, as long as the equipment to shred and extrude it is accessible.

EDM is awesome and if it can plunge you just need a cheap mill to make the dies out of graphite

The Bettawire looks absolutely amazing. I was wondering when someone would build something like this. I'll wait another year or two to let them iron out the kinks, but I'm pretty sure that I will buy one of those sooner or later.

Amazing what was created in the face of adversity (job loss). Brilliant ideas!

If reliable, I could see purchasing a larger unit for my engineering department. I would love one for EDM cutting large gears. 40k USD would be a good target price for a large corporation to not blink twice on it.

I'mma definitely send some filament to that project, and give them some donation as well. That's an awesome project that'll help a ton when it comes to finding replacement colors, or colors that might look good together.

I thought about going to. RMRRF. Wish I had cause I probably would've met that stand and have been able to donate in person. Though.. I actually picked up like 15 spools of filament that Saturday from someone who was leaving the hobby. So, I guess I may have lost out on that deal if I did go. (100 bucks for I believe 14 spools of PLA, and 2 spools of TPU. Don't remember exactly. Most were 800+ grams left. Only two had less)

With an EDM machine I could at last make use of the titanium and tungsten I have in my scrap box. It would even cut tungsten carbide heating elements.

the shredder is by far the most interesting, ontop of a cheap shredder we need a cheap filament creator (cheaper than the one you tested already) and cheap filament dryer
