News Ecut

Perfect and impeccable.

In front of a piece of this kind (about 60×40 mm x 4mm thickness) any good mechanic stops to reflect.

The first question you ask concerns the mind of those who designed it!

Once you have ascertained that this is the way to do it, you begin to think about how to do it. Work center, broach for the teeth of the hole, teeth of the half-corona,.. If then the material is difficult, or must be treated the matter becomes even more complicated.

In the end, only wire erosion remains. If you already have it, that’s fine, otherwise with traditional processes it’s a nice headache,

But with wire erosion, the cost is still high. The removal times are the same as they are, the placing times, with the need to respect guidelines and phases, too. If we put too many pieces one on top of the other to gain some time, there is the trap of the barrel effect, so the precision goes to be blessed …

If your competitor has an E.cut, he’ll almost certainly take the order!

With E.cut you can easily “pack” about fifty pieces and cut them all in one go.
Since there is no beating effect, from the first to the last will be in the couple of hundredths of tolerance.

Add that the hourly cost of exercise is more than ten times lower, so even if you go over it again to bring the roughness up to 0.8 Ra, the final cost will still be extremely low.

I’ll cost you.

If you make your customer pay half of what it would cost him with a conventional wire, he’s very happy, and you still earn a lot of money!

Probably that’s why those who own an E.cut don’t care much about letting them know!

The execution of the housings of the electronic boards in the baskets (racks), would benefit greatly from the processing with wire erosion. However, this process is not suitable for designers of aeronautical materials, and for anyone who has to produce parts that will be subjected to extreme stress and risk of breakage.
For many, hostility is considered unfounded, but in reality there are reasons. In fact, the ellectrosion, because of its principle of operation, causes surface hardening, and very dangerous microcracks because ‘trigger of possible breakage. The phenomenon is well known by mould makers and by those who produce dies for extrusion.

The E.cut technology is basically that of wire erosion, but the peculiarity of being able to slide the wire from 60 to 100 times faster, allows to increase the number of discharges per second, and decrease the intensity. The result is a much lower material “stress”.

In-depth laboratory analyses carried out in one of the most famous Italian research and testing centres for materials, found on the same material (ERGAL 7075) “… the presence of a slight deformed/concred layer…” for processing with conventional wire EDM, and instead “… the absence of microstructural alterations…” for processing with E.cut.

The possibility of running the wire so fast is given by the fact that the wire is not thrown away, but is wound/unwinds on a drum, being used for a very long time. The cost of the process is drastically reduced.
Even if the problems related to cracks and hardening are not relevant, the cost of making a basket is reduced with E.cut from 10 to 20 times compared to conventional wire erosion.
