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
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.
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
A customer cutting sapphire wafers contacted us two months into production for technical support: his wire life had dropped from the 150 hours we’d specified to about 80 hours. We
A customer once asked us why two visually identical diamond wire loops — same diameter, same diamond grit size, same advertised tension rating — gave them wildly different cutting results.
Do you know how large companies cut graphite, which is a hard black block? Special tools make it possible to make clean, smooth cuts. After working in the field for
We had a cutting line producing 300μm silicon wafers with ±25μm TTV — three times the spec limit. The operator swore the wire was defective. Static bench testing showed the
