  • Publication number: 20220016741
    Abstract: A workpiece grinding method includes a groove formation step, a groove removal step, and a full surface grinding step. In the groove formation step, the workpiece is ground by performing grinding feed of a grinding unit while rotating a spindle without rotation of a chuck table, so that an arcuate groove is formed with a depth not reaching a finish thickness on a side of a back surface of the workpiece. In the groove removal step, rotation of the chuck table is started with the spindle kept rotating, so that the groove is ground at side walls thereof and is removed from the workpiece. In the full surface grinding step, grinding feed of the grinding unit is performed while the spindle and chuck table are rotated, so that the workpiece is ground in an entirety thereof on the side of the back surface until the workpiece has the finish thickness.
