Every cutting diamond wire application comes down to four numbers: wire speed, wire tension, feed rate, and wire diameter. Get these right and the process runs itself — clean cuts,
A cutting diamond wire loop doesn’t fail all at once. It degrades gradually — grain by grain, pass by pass — until the cutting performance drops below what the job
Has anyone ever seen the diamond loop stop a big cutting machine because it was dirty or loose? In the 11 years I’ve worked with this equipment, I’ve seen a
Is cutting in a lab a way to lose small pieces? Yes, that’s right. A lot of time and money is wasted when samples are lost in the lab. Little
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
±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
Most engineers setting up their first diamond wire cut ask the same question: how fast should the wire run? The short answer — for most hard and brittle materials, somewhere
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.
A sapphire cutting customer switched from traditional spool-based diamond wire to our endless diamond wire loop last year. He’d been running his cutting line at 20 m/s with a reciprocating
We spent three days debugging a cutting line that was producing wafers with a periodic waviness — clean cuts for 80% of the wafer surface, then a recurring ridge pattern
