News Ecut

Of course, the latest generation of tools have often helped to solve the problem of machining difficult materials such as stainless steel, titanium, inconel, monel, kidney’, ecy…,….
The machining of alloys whose characteristic is to harden at the high temperatures developed by the cut, is still to be addressed with great care, because the mistakes cost dear, very dear, given the high cost of the material.

Wear, breakage, and therefore the cost of tools often affects in an unexpected way. The risks, and the “rognosis” of the processing of these materials leads to estimates that take into account all this, and therefore to high final costs, and to the loss of orders that would be interesting.

Wire erosion would be the ideal solution: no influence of the toughness and hardness of the material, absolute precision of machining, no broken or worn tools, no chips, but scrap resaleable at cost.
Unfortunately, the high hourly cost, (from 5 to 8 euros/hour of only operating cost!), makes it impractical to adopt it!

The working with E.cut represents in these cases a “magic” and revolutionary solution.

The hourly cost of less than 0.4 €/hour of E.cut is the basis of the “magic” that brings the cost of machining this piece to less than a tenth of the previous milling.
Precise, clean and burr-free. An impeccable solution.

The E.cut technology, with the possibility to cut thicknesses up to 300 mm already with the smallest machines, allows to revolutionize and to face in a totally new way the “process” to obtain certain pieces.

These could be the expressions of those who bought a Used Wire Erosion instead of an Ecut.

The irony is evident, but some simple considerations make the images very plausible.

The following table, allows to compare, in a single and synthetic given the reason.

For wire erosion are considered: wire, distilled water, ion exchange resins, filter cartridges, wear parts. The annual maintenance costs have been calculated as if the machine were new, while the risk with a used machine is much higher, and at higher costs.

For Ecut are considered: Wire, liquid/sap to be emulsified with normal water, wear parts, and routine maintenance. (practically non-existent for several years on new machine)
It is evident that considering a use of 3000 hours, (quite low value for an erosion, machine that operates day and night), the difference in cost of management is over 10,000 € / year.

Other factors must be considered:

1) The management of wire erosion is much more complex and demanding than the management of Ecut.

2) Ecut is more precise than used wire erosion.

3) The smallest Ecut cuts up to 300mm thickness. No wire erosion that cuts this thickness can cost, even if used, less than a new Ecut,

4) Ecut allows to overlap pieces to be cut, without suffering from the barrel effect.

5) Ecut does not work with an immersion tank, so it is possible to cut even large pieces.

6) Ecut technology does not cause surface hardening, nor does it trigger microcracks, allowing it to be used even in sectors where normal wire erosion is prohibited. ( Aviation ).

7) At the price of any used wire erosion, (in good condition), it is possible to buy an Ecut with the possibility of cutting, X,Y,Z, considerably higher.
