Abstract
A method of grinding a workpiece includes a first grinding step of adjusting the relative tilt of a chuck table and a grinding wheel to a first state and bringing grindstones into abrasive contact with the workpiece to grind the workpiece, and a second grinding step of adjusting the relative tilt of the chuck table and the grinding wheel to a second state that is different from the first state and bringing the grindstones into abrasive contact with the workpiece to grind the workpiece. In the second grinding step, the workpiece is ground under a condition for causing the workpiece to have a smaller surface roughness than that in the first grinding step.
