Zusammenfassung:	The present invention relates to a method for reproducing display manufacturing process parts, which corrects flatness while increasing the hardness of the display manufacturing process parts. To this end, the method comprises: a heat treatment and correction step of naturally cooling display manufacturing process parts while performing primary heat treatment and first correcting flatness along with the heat treatment; a hardening heat treatment step of increasing hardness by hardening heat treatment of the display manufacturing process parts after the heat treatment and correction step; a reproducing step of performing reproduction by removing a process film or process contaminants attached to the display manufacturing process parts; a step of secondarily correcting the flatness of the display manufacturing process parts without heat treatment; and a step of rinsing and drying the display manufacturing process parts. 본 발명은 디스플레이 제조공정 부품의 재생 방법에 관한 것으로서, 디스플레이 제조공정 부품의 경도를 향상시키면서 평탄도를 교정하는 디스플레이 제조공정 부품의 재생 방법에 관한 것이다. 이를 위해 디스플레이 제조공정 부품을 1차적으로 열처리하면서 자연 냉각시키고, 열처리와 함께 평탄도를 1차 교정하는 열처리 및 교정 단계, 열처리 및 교정 단계 후에, 디스플레이 제조공정 부품을 경화 열처리함으로써 경도를 향상시키는 경화 열처리 단계, 디스플레이 제조공정 부품에 부착된 공정피막 또는 공정 오염물을 제거하여 재생처리하는 단계, 열처리 없이 디스플레이 제조공정 부품의 평탄도를 2차 교정하는 단계, 디스플레이 제조공정 부품을 린스 및 건조하는 단계를 포함하는 것을 특징으로 하는 디스플레이 제조공정 부품의 재생 방법이 개시된다.
