Abstract: uch attention is paid to the development and use of ceramic materials in China. Pre-cision grinding is of high importance to make use of ceramic materials in various areas of high technology.An investigation on the precision grinding of zirconia workpiece used for tensile test is reported.A new type of fonn dresser developed by the authors is used for truing and condi-tioning the arctype diamond wheel.The surfaee finish,profile in the arc portion and symmetry of the workpiece are discussed.

Key words: zircoma, ceramics, precision grinding, form dressing
