Abstract

The invention discloses a forging and pressing process for a low-impurity steel cutter. The forging and pressing process comprises the following steps that A, firstly, cutter machining raw material steel is put into a hot die forging press to be forged; B, the forged cutter is put into a heating furnace to be heated; C, the cutter is taken out, and the cutter is immediately put into a quenching furnace for quenching; D, the quenched cutter is subjected to heat treatment; and E, finally, the cutter subjected to heat treatment is subjected to grinding machining. The forging and pressing technology is easy to operate, and the obtained steel cutter is high in hardness, good in abrasive resistance, high in corrosion resistance and low in forging and pressing cost.
