and conducted research for various polishing applications. Figure 10.40
shows the schematic diagram of MAF apparatus. A cylindrical workpiece
is clamped into the chuck of the spindle that provides the rotating motion.
The workpiece can be a magnetic (steel) or a nonmagnetic (ceramic) material,
the magnetic eld lines go around through the workpiece. Axial vibratory
motion is introduced in the magnetic eld by the oscillating motion of the
magnetic poles relative to the workpiece. A mixture of ne abrasives held in
a ferromagnetic material (magnetic abrasive conglomerate (Figure 10.41)) is
introduced bet ...
