PROBLEM TO BE SOLVED: To control a grinding feed means so that a grinding wheel does not lose its spontaneous edge-sharpening action in case a plate-like workpiece formed of hard-to-be-ground material is subjected to grinding.SOLUTION: A grinding method including use of a grinding device 1 includes: a first grinding feed step, in which, when a loading value of a grinding wheel 15 acting on a plate-like workpiece W has reached a predetermined threshold value, a control section 7 brings a grinding feed means 20 to raise a grinding means 10 at a prescribed grinding feed velocity; and a second grinding feed step in which, when, due to the raise, the loading value of the grinding wheel 15 acting on the plate-like workpiece W is found to have no load, the control section 7 brings the grinding feed means 20 to lower the grinding means 10 at a predetermined grinding feed velocity. The first grinding feed step and the second grinding feed step are alternately repeatedly performed. Consequently, even if the plate-like workpiece W formed of a hard-to-be-ground material is put to grinding, the grinding wheel 15 is free from losing its spontaneous edge-sharpening action, with the resultant continuation of grinding being performed on the plate-like workpiece W. |
