The invention belongs to the technical field of track link section machining, and particularly relates to a machining process of a large-size forging track link section, and the track link section. The machining process comprises the following machining steps that S1, annealing treatment is conducted, specifically, annealing equipment is prepared; S2, blanking is conducted; S3, phosphorization andsaponification treatment are conducted; S4, die forging forging-pressing forming is conducted, specifically, a blank is placed on a track link section die, the die is fixed to large forging equipment, the forging pressure of the forging equipment is greater than 10000 tons, during forging, the blank is heated to be within the range of 1200+/-25 DEG C, and the center and surface temperature difference is less than or equal to 50 DEG C; S5, punching and trimming are conducted; S6, quenching is conducted, specifically, the large-size forging track link section is quenched, continuous induction quenching is conducted, the continuous scanning heating speed is 350-380 mm/min, tap water serves as a quenching medium, and the water temperature is 20-40 DEG C; and S7, tempering is conducted. The large-size forging track link section is good in surface quality, good in mechanical performance, and not prone to brittle failure.
