CNC DIAMOND WIRE SAW

Price from 22’000 EUR

PURPOSE:

Diamond wire cutting technology is not new, it has been existing for more than 50 years. Basically, the equipment using fixed abrasive wire-cut technology originated from special design multi-wire machines which work with a straight cut only with high performance. It was used, in most cases, for the radio-electronic industry for precision cutting of silicon carbide. In the 21st century, the relevance of this technology has increased.

There are a huge number of new non-conductive materials which require economical cutting as materials based on carbon fiber, special alloys with low inductance but very high hardness, sandwich structure materials (composites) using ceramics and various plastics, compound materials, various minerals, as well as synthetic porous and brittle materials.

We, as manufacturers and sellers of electro-erosive equipment, constantly faced requests for test processing of various materials that are on the verge or beyond the capabilities of electro-erosive processing. Of course, the tests were not successful. However, it pushed us to the idea of creating a universal machine that works on the principle of abrasive friction of diamond wire on the workpiece and using the proven mechanical part with almost no modifications from the M series EDM machine.

The control Cabinet was correspondingly modified for 2‑axis control and the CNC system used was the MEATEC CNC system, which was developed by SPE MEATEC itself. The equipment turned out to be universal, inexpensive and reliable. The CNC abrasive wire-cutting machines of our MK series are widely used for cutting silicon carbide and other carbide alloy materials, graphite electrodes, plates made of epoxy resins, marble, jade, optical glass, ceramics, ferrite, semiconductor materials, refractory bricks and other non-conductive and conductive materials, which hardness is a little bit less than diamond.

FEATURES:

Machining any materials with hardness just a little bit less than diamond.
Мinimum cutting thickness, equal to 0.33 mm, allows to save processed material.
