Grinding wheel, method for grinding workpiece, and method for manufacturing chip

Abstract

A grinding wheel 1 is for grinding a back surface side of a plate-shaped workpiece having a front surface and a back surface on the side opposite to the front surface, and includes a wheel base 10 having a first surface 11 and a second surface 12 on the side opposite to the first surface 11, the first surface 11 side being mounted on a spindle rotating in a predetermined rotation direction, grinding abrasive products 20 disposed on the second surface 12 side of the wheel base 10 and having a bottom surface 21 in contact with the back surface of the workpiece, and a movement controller 30 that movably controls the grinding abrasive product 20 such that the contact area of the bottom surface 21 is changed in terms of the bottom surface 21 of the grinding abrasive product 20 with respect to the back surface of the workpiece.
