Contour Cutting Magnet Materials: Guide

Key Takeaways Craft cutters such as Silhouette machines only handle flexible rubber-bonded magnets up to about 1 mm thick; sintered NdFeB, SmCo and hard ferrite require industrial cutting equipment. Compared with laser (heat demagnetization risk), waterjet (rough edges) and CNC milling (slow), the diamond wire saw delivers the best combination: ±0.02 mm precision, mirror-finish edges and under 5% material waste. Diamond wire saw cutting is CNC-controlled and coolant-managed below 50 degC, achieving contour accuracy of ±0.02 mm and edge roughness under Ra 0.5...

Magnetic Materials: Properties & Applications Guide

Key Takeaways Magnetic materials fall into three families: permanent magnets (NdFeB, SmCo, AlNiCo, フェライト), soft magnetics (silicon steel, soft ferrite, amorphous and nanocrystalline alloys, permalloy) and functional materials (magnetostrictive, recording media, spintronics). Each family fails differently under cutting: NdFeB microcracks and demagnetizes, ferrite crumbles at the edges, amorphous ribbons are extremely hard (up to 900 HV) and thin, and nanocrystalline alloys degrade above 150 degC. End-use magnetic performance depends on edge quality (flux leakage), dimensional accuracy (air gaps) and freedom from heat- or...

Precision Cutting of Ferrite Magnets: Guide

Key Takeaways Ferrite (セラミック) magnets are sintered iron oxide with strontium or barium carbonate: cheap, corrosion-resistant and stable up to 250 degC, but hard and brittle — so cutting method directly decides yield. Grinding leaves 50-100 micrometer micro-cracks and runs slowly; laser adds a heat-affected zone that alters magnetic properties; waterjet leaves Ra >3 micrometer edges needing polishing. Diamond wire saw cutting is the best fit: a 0.1-0.3 mm diamond-coated wire gives chip-free edges (Ra <0.5 micrometers), no heat damage, ±0.02 mm tolerances...

Precision Cutting of Magnetic Materials

1.What Are Magnetic Materials? Magnetic materials are a fundamental class of substances defined by their ability to generate a magnetic field and to respond in a significant, measurable way to an applied magnetic field. This property originates from the quantum mechanical spin and orbital motions of electrons within the atoms, which create tiny magnetic “dipoles.” The macroscopic magnetic behavior of a material is determined by how these microscopic magnetic moments are arranged and interact with one another. Key Takeaways Magnetic materials fall into...

Can CNC Milling Cut Magnetic Materials?

Key Takeaways CNC milling can cut softer magnetic materials — low-carbon electrical steels, nickel alloys like Permalloy and soft ferrites — but struggles with hard, brittle magnets. On NdFeB, hard ferrites and high-carbon steels, milling faces rapid tool wear, heat that can demagnetize the part, and brittle fracture at edges. Diamond wire loop cutting is the better route for hard magnetic materials: thin kerf saves expensive material, coolant prevents demagnetization, and tolerances reach ±0.05 mm crack-free. Rule of thumb: soft magnetic steels and nickel...

Crack-Free Glass Machining: ダイヤモンドワイヤーソー

Key Takeaways Optical glass is brittle and sensitive to thermal shock; cracks usually start at the exit edge of the cut. Diamond wire machining keeps cutting force low and constant, producing crack-free edges. Coolant and feed control matter far more than cutting speed. Why Crack-Free Cutting Matters in Optical Glass Machining Optical glass, such as SCHOTT B270, N-BK7, and fused silica, is widely used in high-precision applications like camera lenses, laser optics, medical imaging, and aerospace components. でも, traditional cutting methods—such as diamond blade...

Diamond Wire vs Blade: Optical Glass Surface Test

In precision optical manufacturing, surface quality directly impacts component performance. Our controlled tests reveal: - Endless diamond wire saws achieve 60% lower surface roughness (Ra 0.18µm) vs blades - Blade cutting generates 3-5X more subsurface cracks at 100µm depth - Wire saw kerf loss is 40% narrower (0.25mm vs 0.42mm) This study quantifies these differences using SCHOTT B270 glass samples analyzed with white-light interferometry and SEM imaging. The surface comparison below is one part of a wider method described in optical glass cutting. Diamond Wire Cutting...
