往復動装置。 a grindstone head rotatably supporting a whetstone shaft with a whetstone attached to its tip; a drive cylinder that reciprocates the whetstone head in the direction of the whetstone shaft; and a drive cylinder that moves back and forth in a direction substantially perpendicular to the direction of movement of the whetstone head. A grindstone reciprocating device for an internal grinding machine, comprising: dressing means for dressing the grindstone; a set moving speed of the grinding wheel head that is stored in the set moving speed of the grinding wheel head, and a moving speed of the grinding wheel head detected by the grinding wheel head speed detecting means and a set moving speed of the grinding wheel head that is stored in the set moving speed of the grinding wheel head that is stored in the set moving speed of the grinding wheel head. and a grinding wheel head speed comparing means for calculating the difference between the two, and supplying the drive cylinder to the drive cylinder so that the difference between the moving speed of the grinding wheel head calculated by the grinding wheel head speed comparing means and the set speed is within a predetermined range. A grindstone reciprocating device for an internal grinding machine, characterized in that it is equipped with a hydraulic oil amount control means for controlling the amount of hydraulic oil.
