The technical field of saw blade grinding machine refers to a new type of electric saw blade grinding machine that can adjust the Angle. The saw blade grinding machine adopts a fixed motor and a grinding wheel to grind the saw blade. The grinding machine of this structure realizes the efficient operation of the mechanical grinding saw blade, including a guide rail, a grinding wheel working device, a gear working device and a gear gear device. The grinding wheel working device includes a transmission motor and a grinding wheel, the transmission motor drives the grinding wheel to rotate, the guide rail seat and the gear shifting device are installed on the work table, which is characterized in: An adjustment seat is arranged between the grinding wheel working device and the guide rail seat for vertically adjusting the longitudinal Angle of the rotating motor, and an Angle adjustment mechanism is arranged on the adjusting seat to adjust the horizontal position Angle of the grinding wheel to adjust the Angle in all directions.
