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.

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane). Surface texture is one of the important factors that control friction ...

A Nano-grinding centre as shown in Fig. 2 (a) developed by Aurich et al. was used to integrate the fabrication of micro-pencil grinding tool and perform the micro-grinding of silicon [1]. Dimension of the machine was 900×600×600 mm and it could provide a wide speed range of 15,000 to 160,000 rpm.

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.
