  GrindBall: an advanced micro-grinding tool | Production …

  2013420 · The choice of material for both the grinding sphere and the electromagnets is vital in order to be able to determine the sphere’s position and control it. In particular, different materials (e.g. ferrite or powder composites) and improving the distribution of magnetic quality and mechanical stability need to be examined.
