Endless Diamond Wire Resource Center

In a traditional wire saw, the wire runs from one spool to another and back — hundreds of meters of wire, reciprocating through the cut zone. In an endless wire saw, the wire is a closed loop. No spools. No reversal. The wire circulates in one direction, continuously, like a belt. That loop — the…

±0.03 mm. That’s the cutting precision tolerance on Vimfun endless wire saws — and it’s a number we stand behind across glass, ceramics, quartz, and sapphire applications. But tolerance on a spec sheet and accuracy on a finished part aren’t the same thing. One is what the machine can do under ideal conditions. The other…

A 0.5 mm diamond wire running at 60 m/s removes material from a sapphire boule without generating measurable heat at the cut zone. No blade vibration. No thermal stress cracks. Just a clean kerf less than 0.6 mm wide. That’s the core promise of cutting diamond wire — and understanding how it actually works is…
