Claims

[Claims for Utility Model Registration] For dressings that are rotatably and slidably supported along the axial direction and have a diameter larger than the width of the grinding surface of the upper and lower grinding wheels of a double-head surface grinder at the tip end thereof. a sleeve in which two grindstones and two truing grindstones are installed alternately at the same circumference; a rotary drive device that rotates the spindle to rotate the dressing whetstone and the truing whetstone; and a rotary drive device that moves the sleeve forward and backward to move the dressing whetstone and the truing whetstone back and forth in a straight line. A dressing device for a double-head surface grinder, comprising a linear drive device that provides motion, and an indexing device that rotates the sleeve 90 degrees to index the dressing grindstone and the truing grindstone at predetermined positions. .
