Rare Earth Magnets at the Center of Modern Industry
Neodymium-Iron-Boron (NdFeB) and Samarium-Cobalt (SmCo) are the world’s most powerful permanent magnets. They are used in electric motors, wind turbines, MRI systems, and industrial drive technologies. As global electrification continues to accelerate, demand for these high-performance materials is growing rapidly—along with the need to machine them with maximum precision and minimal material waste.
Key Challenges
• Brittle crystal structure – high risk of chipping during cutting• Strong magnetic fields – make clamping and positioning more challenging• High susceptibility to corrosion – water cooling should only be used with suitable additives• High material costs – every millimeter of cutting waste increases production costs
The DRAMET Solution
DRAMET diamond band saws equipped with fine-grit diamond-coated saw bands and operating with minimal cutting pressure produce clean, chip-free cut edges when machining NdFeB and SmCo magnets. Custom-designed clamping solutions for magnetic workpieces can also be supplied to ensure safe handling and maximum process stability.
Conclusion
The market for rare earth magnets is expanding rapidly as the global energy transition and electrification continue to accelerate. Manufacturers seeking economical and highly precise machining need cutting technology that meets these demanding requirements. DRAMET delivers exactly that.
