PURPOSE: To provide a tool grinding machine excellent in the operability by the manual operation without preparing a complicate program or the like.

CONSTITUTION: A turning table 8 is provided on a base 3 of a tool grinding machine 1 in a manual and turnable manner. A spindle 16 which is turned at the turning angle synchronous to the turning angle of the turning table is provided on the turning table 8, and an end mill E Is provided on the spindle 16 in an attachable/detachable manner. A grinding wheel G1 to grind the edge rear part of the end mill E and a grinding wheel shaft driving motor 24 to drive the grinding wheel G1 are provided on the base 3. In addition, a first encoder to detect the turning angle of the turning table 8 and a second encoder 19 to detect the rotating angle of the spindle 16 are provided on the tool grinding machine 1, and the rotating angle of the spindle 16 is synchronized to the turning angle of the turning table 8 based on the detected signal from the first encoder and the second encoder 19.
