Cutting SmCo and Ferrite Magnets with Diamond Wire
SmCo magnets crack without warning. We’ve had a customer send us a batch of Sm2Co17 arc segments — 40 pieces total — and ask why their blade saw was destroying

Hard metal cutting is where most conventional tools fail fast. Titanium alloys, tungsten, and molybdenum share a reputation that anyone who’s machined them knows well: they destroy tooling. Ti-6Al-4V eats
Buying a magnet cutting machine is a decision most shops only make once every 5–10 years. Get it right, and the machine pays for itself in reduced scrap, better surface
Something went wrong with your cut. The edges are chipped, the surface is grey, the thickness varies across the slice, or the wire broke mid-cut and now you’ve got a
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
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,
