The invention relates to the technical field of low-temperature curing processes, in particular to a grinding wheel low-temperature curing process comprising the following step I of burdening; the step II of mixing; the step III of die filling; the step IV of primary heating, placing a die in a hot press for segmented heating; the step V of cooling; the step VI of reheating, placing the die in thehot press again, gradually heating to 240 DEG C from original 0 DEG C at the rate of 10 DEG C per minute, and finishing the whole process in closed environment; and the step VII of taking out the diefrom the hot press, wrapping the die with thermal insulation materials, and cooling the die slowly. According to the grinding wheel low-temperature curing process, by adopting staged and gradual temperature rise methods, the bonding capacity between abrasive particles and binding agents is improved, so that the hardness and mechanical strength of a grinding wheel are improved; by adopting the low-temperature curing proces
