ABSTRACT
This paper compares the grindability of conventionaland nanostructured material coatings in terms ofnormal grinding force， specific grinding energy， surfacefinish and surface topography. Material removalmechanism is correlated with the microstructures of thematerials such as material grain size. The effect of thedecreasing material grain size in nanostructuredmaterials on the grindability is studied.
1 INTRODUCTION
In grinding of ceramics， the effects of grindingprocess parameters have been extensively studied (e.g.，Kirchner and Conway， 1985;Tönshoff and Brinksmeier，1988; Blake et al.， 1988). It is of equal importance tostudy the influence of material microstructure. One ofthe material microstructures is the grain size， whichinfluences the mechanical properties， such as h
