Rare Earth Magnets are expensive, brittle and hard permanent magnets made from — Neodymium (NdFeB) and Samarium Cobalt (SmCo).

They demand careful & precise grinding. 

Nissei’s rigid structure ensures smooth grinding without breakages, protecting your high-value magnet batches.

Nissei offers Double Disc Grinding solutions for below processes in magnets manufacturing:

①Material Block Grinding
After sintering and pressing, two surfaces are ground on Nissei grinder followed by slicing process.

For cube magnets without a slicing process, all six faces are ground on Nissei Double Disc Grinders.

②Mass Production after Slicing
High Volume Magnets such as those for EV motors,

require grinding on all six faces, and Nissei provides an automated grinding line.

③Large Size Magnets
Magnets larger than those for EV motors are ground on Nissei machines with large-diameter grinding wheels.

Nissei Advantages: 

– Rigid box-type construction.

– Patented features make operation simple and precise.

– High Productivity, High Precision with highest levels of repeatability, Maintenance free operations with faster return of investments.

– Nissei Grinders offered as individual machines or as line for grinding of multiple faces of magnets.

– Well Proven technology for Rare Earth Magnet grinding across Japan, Europe & USA.

– Strong Sales, Service, After sales and Technical support with over 85 Nissei machines installed in India.

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.
