Thin diamond blade is widely used for the precision slicing of electronic parts such as magnetic head. It is well known experientially that some properties of blade have a great influence on the machining characteristics of workpiece, i.e. the work damage and the blade wear.ln order to understand the relation between the properties of blade and the machining characteristics, the mechanical properties of thin diamond blade are investigated in detail through the measurements of the tensile strength, the dynamic visco-elasticity and the wear resistance of bonding material. It is found from the experiments that there are notable differences in the mechanical properties of various blades.
