The present invention relates to a centerless grinder which is provided to process various objects to be processed, by comprising: a fixating holder (30) which has a bending shape in order to be fastened to both ends of the central axis of an adjusting grinding roller (20); a moving bushing (40) which has an internal surface formed of a screw thread in order to penetrate the center area of the fixating holder in a single body; and a moving screw (50) whose one side is wound to the moving bushing and includes a guide socket (51). The rotation of the moving screw is conducted by mutual gearing between a pinion gear (60) which is installed to the other end of the moving screw, and a rack gear (70) which is horizontally arranged in order to be geared to the moving screw. While the position of the moving bushing (40) varies according to the rotation direction of the moving screw (50), the horizontal transfer of the fixating holder (30) is conducted in order to regulate the gap between the adjusting grinding roller (20) and a fixating grinding roller (10). |
