Relationship of Grinding Textures and Surface Friction Coefficient of Common Steels

Distinct textures of 0°,30°,45° on the common steels of 20,45 and 40Cr were modified by grinding.Surface roughness and friction coefficient of grinding textures were studied.The results show that under the same conditions of grinding machining parameters,the surface roughness of the materials with different grinding textures from big to small was 0°,30°,45°.The friction coefficient as the texture inclined to the direction of movements with certain angle was smaller than those as the texture vertical to the direction of movement.Compared with 45,20 steels the effect of grinding texture on the friction coefficient of 40Cr steel was less.
