Linear ball guide way are widely used in machine tool feed drives. But it has a friction force which varies periodically. If friction force's periodically changing cannot be suppressed by the control system, it appears in positioning deviation and motion error happens. In this paper, we examine the effect of the surface roughness of guide way to the position deviation and friction force in linear ball guide way. So roll the rolling element in varying surface roughness rails and measured friction force experimentally.
