PROBLEM TO BE SOLVED: To provide a grinding machine for reducing a flow rate of a grinding liquid, and reducing motive power of a grinding wheel shaft motor even if there are fluctuation in a grinding point by rotary motion of a workpiece and fluctuation in the grinding point by abrasion and truing of a grinding wheel surface. SOLUTION: In this grinding machine, a grinding liquid supply nozzle supplies the grinding liquid to the grinding point. The grinding liquid jetted from the grinding liquid supply nozzle, is supplied on the upstream side of the grinding point in the rotational direction of a grinding wheel even when a grinding wheel diameter is minimum. A shape of a tip part of the grinding liquid supply nozzle is formed in a tapering-off shape of 40°or less to a nozzle port or a straight shape of maintaining a shape of the nozzle port in 10 mm or more.
