Abstract
An apparatus for truing the cylindrical outer peripheral grinding surface of a grinding wheel includes a truing head which is movable toward or away from the grinding wheel in a first direction which is parallel to the grinding surface and in a second direction which is perpendicular to the first direction. A truing wheel is rotatably supported on the truing head, has a truing surface and is movable with the truing head for truing the grinding surface. A contacting detection member is secured to the truing head, projects therefrom toward the grinding surface and has an end surface which can be brought into contact with the grinding surface. A device is provided for detecting the contact of the end surface of the detection member with the grinding surface and producing an output signal upon detecting their contact. Three feed control devices are provided to move the truing head in various directions. Detecting devices and memories are provided for detecting the position of the truing head and for controlling movement of the head.
