PROBLEM TO BE SOLVED: To provide a grinder capable of simplifying the structure of a truing device.SOLUTION: The grinder includes a truing device 60 disposed on a prescribed position on the grinder for grinding a workpiece W by controlling a grindstone 32 in the X-direction and in the Z-direction, for truing a processing surface of the grindstone 32. The truing device 60 includes: a movable base 70 disposed movably in the X-direction in the pressed state to the X-direction by an X-direction pressing mechanism 62 with respect to a support medium; and a truer 77 disposed rotatably around the axis in the Z-direction with respect to the movable base 70, for truing the grindstone 32 by being follow-up rotated in the contact state with the grindstone 32 by a pressing force of the X-direction pressing mechanism 62. |
