The utility model provides a cutting saw plate grinding machine which is ingenious in structural design and easy and convenient to operate. The sliding stability of the cutting saw plate grinding machine can be well ensured, the grinding angle deviation can be better avoided, and the grinding reliability can be ensured; through the combination of the cutting saw plate grinding machine, a grinding wheel type grinding unit structure with an angle-adjustable grinding groove and an installation structure of the grinding wheel type grinding unit structure, the service life of a grinding unit can be greatly prolonged, grinding is made finer, and the grinding finish degree is increased; sawtooth breakage is not prone to happening when a grinding wheel conducts rotating friction for grinding, the sawtooth deviation conditions can be corrected when the grinding groove of the grinding wheel extrudes sawteeth in a rolling mode in the grinding process, and therefore the good grinding effect is achieved, and a device implementation scheme is provided for solving the problems that the manual grinding operation is complex, the sawtooth cutting edge grinding angle is not good, and sawtooth breakage is prone to happening.
