The mesh-type polishing tool, the backing of which is knitted with almost flat cross-sectional shaped polyester fiber (average diameter : 125μm) is a newly developed polishing tool. The polishing tool has meshes of size about 100μm. And fine abrasive grains are coated on both sides of the backing. Chips generated during the grinding process can easily go through the mesh. As a result, the tool can grind the surfaces of the workpiece under constant conditions as loading does not occur. To clarify the grinding characteristics of this polishing tool and its features, in this research, the tool performance was evaluated by comparing the experimental results with the most used conventional polishing tool. Moreover, in order to find out the optimum grinding conditions of the mesh-type polishing tool, finishing experiments were carried out by changing the effective grinding parameters and observing the experimental results such as accumulated stock removal, surface roughness, tool surfaces and so on. Finally, the important grinding conditions affecting the amount of stock removal and surface roughness were clarified from the analytical results of multiple regression analysis.
