This study has been undertaken in order to examine the relation between the luster of finished surface and the adhesion property of materials cut usually called as affinity. High speed steel tool and carbide tool are used for the comparison of performance. Brass, Al alloy, pure iron and pure titanium are used as materials cut. Adhesion tests in the vacuum furnace are carried out for each combination of the above tools and materials cut and their results are compared with the luster and roughness of the finished surface. The results obtained are as follows. (1) The luster of finished surface has a close relation to the roughness of finished surface. (2) The effect of diamond tool for the luster of finished surface is due to the less roughness of finished surface and affinity for materials cut. (3) Diamond tool shows an excellent luster in the finishing of brass and Al alloy in the correspondence with the less affinity for them. But, it shows a poor luster in the finishing of pure titanium and pure iron which have better affinity.
