The invention relates to the technical field of drilling, in particular to a novel drilling process which comprises the following steps: acquiring the straightness of a hole in a plurality of drilling processes; determining the working height of the electric grinder based on the variance of the straightness of the hole; determining a first corresponding pressure of a drill bit of the electric grinder based on the temperature rise rate of the shell of the electric grinder, or preliminarily judging that the interference degree of high-pressure equipment to the electric grinder exceeds an allowable range; the corresponding adding volume of cooling liquid is adjusted based on the drilling roughness; second corresponding pressure of the drill bit is determined based on the drill bit deformation quantity of the electric grinder; an electric grinding machine is fixed to the base according to the determined working height, and the electric grinding machine conducts drilling according to the re-determined drill bit pr
