The Enhancement of Micro Grinding Process by Using NdFeB to Seize Material Dust

By the substitution of ferrite to NdFeB materials, the process of seizing material dust in
micro grinding process will be faster. Magnetic, chemical, corrosion, mechanical and
magnetisation properties of the different materials are described and compared to enable
the replacement. The concept design of magnetic steel attachment is to build a close steel
attachment that can be adhered to pressure vessel so that the material dust will not be
plunged out to the environment work. The sample of bonded NdFeB magnet is prepared by
mixing die NdFeB powder with 5% of epoxy binder, NdFeB magnet also undergoes
Scanning Electron Microscope (SEM) and X-Ray Diffraction (X-RD) test for further
analysis. The final test would be the micro grinding process is operated with NdFeB
bonded magnet placed at the base of the steel attachment.
