News Ecut

These two toothed crowns were becoming a problem! The module is not standard, and there’s no creator ready. As usual the customer needs it right away.
Of course, a CNC milling machine, and so on. But the thickness, and the particularly difficult material make the cost rise, to the point of making it almost prohibitive.
Wire EDM, therefore. But that who owns it is not there waiting for you,… and then a wire erosion has its price!

In many sectors there are not large numbers, and Ecut that between operating cost and depreciation cost does not exceed 3 € / hour is an unsurpassed solution.
If you are in competition with those who own an Ecut, you have no choice in such situations. He takes the order.

Forget the sterile clichés about Chinese living with a handful of rice. Look at the pictures next door. You’ll notice the dirt, which is what’s immediately obvious!
But there are only two people (two!!) who make 19 cars go, who work day and night. The cars, not the people. They do their 8 hours, like everywhere. Just think how much people here in Italy cost you!

Returning to the two crowns from which we started, the client arrived in the afternoon at 4 p.m., and at 9 p.m. his crowns were finished! The next morning he took them away!
Two hours and thirty minutes for the sixteen teeth with a diameter of 200 mm, with perfect geometry, cut without any burrs, and without superficial hardening!
If they had been ten pieces, even better! The smallest Ecut cuts up to a thickness of 300 mm. Then put one on top of the other, just one placement and for 30 hours the machine would have worked… alone.
The total cost is about 7,5 euro… but the customer was very happy to pay 50!

How much does a smear cost?

Often in production the nose is slammed with problems of apparent simplicity but underestimated in terms of cost.
The processing of thin tubes, whatever the material, but especially when expensive and valuable, makes it necessary to take precautions and care that increase costs.
Tubes of a few tenths of a thickness cannot be tightened without criteria, under penalty of deformation. Therefore, shaped pliers and special, special tools, and as such expensive, must be studied.
Cutting with conventional methods, but also with lasers, water, etc., always leaves burrs or micro burrs whose accurate elimination is almost always considerably more expensive than the cut itself.
If the cut is not straight, but has a profile, the use of shearing dies is necessary.

In the presence of large lots, everything is justified, but when there are no large quantities, the matter becomes complicated.
Electroresion has been used for decades to cut the tubes of hypodermic needles, but there, the high numbers have justified the use of special wire EDM machines.
Wire erosion cutting would be ideal. No need to tighten the workpiece, just keep it in place. No burrs, clean and precise cutting, and, given the very thin thicknesses, even short cutting times.
The problem is the high hourly cost of operation, and the fact that these machines are not mixed up with the production men. ( They are not all mould makers ! ).

E.cut represents a revolution.

The hourly cost of operation from 10 to 20 times lower than that of conventional wire erosion, the extreme simplicity of management, and even more ‘the ease’ of use within the reach of any worker, make it unbeatable adoption in these cases.

Incredible cut of 4 superimposed stainless steel tubes. Cutting practically impossible with conventional wire erosion, except with very low cutting speeds.
