Electroless Plating of Micro Pencil Grinding Tools with 5 ...

Micro grinding is a promising process to produce small scale structures in hard and brittle materials. Just like macro grinding processes, a high number of abrasive grits embedded on the grinding tools, are applied. This high number of grits results in low cutting forces on individuall grits and very small chip thicknesses, thus generating surfaces with a high quality.
