The slider mechanism of wheel head by intermittent holding of vertical guideway is proposed and studied. The experimental apparatus is made for the model of the vertical guideway. The grinding wheel head slider is fixed to the vertical guideway during grinding by the elongation of PZT actuator and is released during feed motion in the direction of depth of cut. Metalic slide material is tried to be used for the guideway surfaces without lubrication oil. The characteristics of the static rigidity and the repeated motion of holding and releasing are examined experimentally and considered. Further, method to check guideway space and device to keep constant pressing force are proposed. The results are as follows: (1)Increase of pressing force (holding force (holding force) causes increase of static stiffness. The stiffness is able to be estimated with the relations between contraction and pressed force of guideway surface. It is estimated that the static stiffness of the apparatus on pressing force=P=150 N(Stress=0.3MPa) is more than 6 times of the static stiffness of usual guideway.(2) Good response of repeated motion is obtained. Slider keeps the same position during grinding operation and also the depth of cut 0.05 μm is easily fed.
