I like the simplicity of your chopper. On the commercial machines I have run they put the copper right behind the pinch rollers in the back of the machine. Now their choppers chop the wire into around 3-4 mm long pieces. Because of the design if they don't vary the speed of the chopper to match the wire speed it will jam up into the chopper and usually cause a short. Or the wire will spool out everywhere (It usually does both). Also the cutter head is a special cutter and carbide cut/guide the wire passes thru are expensive. Not to mention the motor that runs the thing. And if you don't have spares. You are in trouble if they need to be replaced and are in the middle of a job. The wire chopper on commercial machines was, for me the most troublesome thing on the machine.

You can use ceramic cutting edges, or insulate it by plastic mounting brackets? Makino never did a cutter like Mitsubishi, they squeeze the wire between the pitchrollers so the wire will form a good ring in the trash bucket. Works really good, but you need more than a 10l bucket for that. As edge precision said it's a pain in the ass on most commercial ones, and they are built good, but still need alot.of maintenance.

This is just awesome! I would have let the feed tube go in tangentially on the lid and placed the chopper rotating radially in the bucket though, to leave more headroom for the cut wire. I suppose that would make the bucket too heavy to carry if it ever got that full.

That's effectively what the machine shop I work for does with their commercial (non-diy) EDMs. There is a acrylic box (one per machine) about 3' on each side that the spent wire spools into. Then when it fills up, they dump it into the brass scrap bin.

It makes poor use of space. The guy above me said that theirs is 27 ft^3, and it will probably only accept 10% of the wire you can fit if you chop it. Then you have problems with being able to stuff thin wire into the box as it gets more and more full. Ever hear of "pushing rope"?

Hi nice job, on my charmilles 510 ( open flush ) it has crimping rollers on the bottom head so as the wire goes through the feed rollers it crimps and then the wire stays flat in the bottom of the machine and after we have run 15k meters of wire i pull out and put in a rig and compress to make a mini bail the scrap people dont like it loose.

Actually the chopper will only be electrified if you chose to make the parts out of conductive material, if you use a ceramic cutting edge there will be no back feed into the EDM machine itself.

I am following this project right from the begining, and a wire edm would be the last important thing for my hobby shop. However, one thing I am worried about is all the pumps and water filtration systems that are needed. Can you make a detailed video on that? Without those in mind, I cannot estimate a cost on how much it would cost me to build such a machine. Thanks! :)

Wouldn't it be easier to drill out the hole on the cutter arm and add a machined/3D printed plastic spacer in between the motor shaft and the cutter arm? That way you wouldn't have to redesign really anything, and you gain the ease of controlling the cutter with your cnc controller.

A new spool costs about 80 Euros, and has 12.000 meter wire on it. With an average speed of 6 meter/minute you can machine 2000 minutes or 33.3 hours. The wire cost is then 2.4 Euro/hour. This is an average, the wire speed must be higher for some parts.

There's more to ToT's style than hands in front of the camera. This complaint makes about as much sense as "all the other newsrooms can't have the anchorman/woman behind a desk looking at the camera, because X news channel used the format first." Even if that bit from ToT was copied, it can be interpreted as an homage to ToT. Imitation is the sincerest form of flattery, and all that.
