NdFeB magnets are strong, compact, and easy to damage during cutting. The problem is not only hardness. In NdFeB magnet cutting, the real trouble usually comes from brittle grain fracture, edge chipping, coating damage, wire vibration, and fine grinding debris trapped in the kerf. That is why a diamond wire saw is often a better
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 carbide inserts because the heat has nowhere to go — its thermal conductivity is roughly 7 W/m·K, about one-sixth of steel. Pure tungsten is harder

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 quality, and faster throughput. Get it wrong, and you’re stuck with equipment that doesn’t match your production reality — either too small for your volume

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 $50 SmCo blank with a groove in it. Before you adjust anything, read this magnet cutting troubleshooting guide — because the most common fix we
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 a sludge that clogs your filtration system for no benefit — ferrite doesn’t corrode in water. And on SmCo, it barely matters which you use,

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 to hold stable flux in a satellite for 15 years without maintenance. Then SmCo is suddenly the only option. The problem is that SmCo is

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 magnet segments go into automotive sensors, micro-motors, loudspeakers, and household appliances every year. And every one of them needs to be cut from a sintered

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 that go directly into bonded assemblies. But for magnets heading into electroplating or precision motor applications, “good enough off the saw” and “ready for coating”

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 input during cutting can permanently damage the microstructure — reducing the magnet’s achievable performance when it’s finally magnetized downstream. We’ve processed hundreds of NdFeB blocks

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 irregular edge damage, and may contain subsurface cracks that won’t show up until the part fails during downstream processing. The material is the same. The
