Rare Earth Magnets are expensive, brittle and hard permanent magnets made from \u2014 Neodymium (NdFeB) and Samarium Cobalt (SmCo).<\/p>\n\n\n\n

They demand careful & precise grinding.\u00a0<\/p>\n\n\n\n

Nissei\u2019s rigid structure ensures smooth grinding without breakages, protecting your high-value magnet batches.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Nissei offers Double Disc Grinding solutions for below processes in magnets manufacturing:<\/p>\n\n\n\n

<\/p>\n\n\n\n

\u2460Material Block Grinding<\/strong>
After sintering and pressing, two surfaces are ground on Nissei grinder followed by slicing process.<\/p>\n\n\n\n

For cube magnets without a slicing process, all six faces are ground on Nissei Double Disc Grinders.<\/p>\n\n\n\n


\u2461Mass Production after Slicing<\/strong>
High Volume Magnets such as those for EV motors,<\/p>\n\n\n\n

require grinding on all six faces, and Nissei provides an automated grinding line.<\/p>\n\n\n\n


\u2462Large Size Magnets<\/strong>
Magnets larger than those for EV motors are ground on Nissei machines with large-diameter grinding wheels.<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

Nissei Advantages:\u00a0<\/strong><\/p>\n\n\n\n

– Patented features make operation simple and precise.<\/p>\n\n\n\n

– High Productivity, High Precision with highest levels of repeatability, Maintenance free operations with faster return of investments.<\/p>\n\n\n\n

– Nissei Grinders offered as individual machines or as line for grinding of multiple faces of magnets.<\/p>\n\n\n\n

– Well Proven technology for Rare Earth Magnet grinding across Japan, Europe & USA.<\/p>\n\n\n\n

– Strong Sales, Service, After sales and Technical support with over 85 Nissei machines installed in India.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\n

Nissei machines are a proven system built for longevity, precision, and reliability.<\/p>\n\n\n\n

For rare earth magnets, there\u2019s no safer or smarter choice.<\/p>\n<\/div>\n\n\n\n

We take this opportunity to introduce Nissei technology for Double Disc grinding to support rare earth magnet manufacturing in India for EV motors apart from aerospace, wind turbines application.<\/p>\n\n\n\n
