CUSTOMER STORIES
Real cutting tests, application examples, and customer-side material results from Vimfun endless diamond wire saw systems.
Pick the wrong coolant for magnet cutting and you’ll know within hours. On NdFeB, water-based coolant turns a freshly cut surface grey with Nd(OH)₃ corrosion. On ferrite, oil-based coolant creates
Samarium cobalt is the magnet material nobody talks about — until the application requires 300 °C operating temperature, or the environment is too corrosive for NdFeB, or the magnet needs
Ferrite is a strange material to machine. It’s technically a ceramic — hard, brittle, electrically non-conductive — but it’s also the world’s most mass-produced permanent magnet material. Billions of ferrite
A diamond wire saw can produce NdFeB surfaces with Ra 0.3–0.5 μm straight off the cut. That sounds good on paper — and it often is good enough for magnets
Sintered NdFeB is one of the hardest permanent magnet materials to cut cleanly. The grain boundaries are brittle, the Nd-rich phase oxidizes fast when exposed to moisture, and any thermal
A clean cut through optical glass looks almost polished — no visible marks, no micro-cracks, no chipping at the edges. A bad cut through the same glass looks frosted, has
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
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
