The invention relates to a supporting machine table. The supporting machine table comprises a plurality of pin holes, supporting pins which can move up and down are accommodated in the pin holes, at least one groove is formed in the walls of the pin holes, balls are accommodated in the grooves, freely roll in the grooves, and located around the supporting pins accommodated in the pin holes, and each ball can roll in the corresponding groove and a part of each ball always protrudes out of the walls of the pin holes due to the shape and the size of the grooves. According to the supporting machine table, the balls are arranged in the pin holes, when the supporting pins are deflected or bent, sliding friction between the supporting pins and the walls of the pin holes is converted into rolling friction between the supporting pins and the balls, generated particles can be reduced, particles adsorbed on a liquid crystal display panel are greatly reduced, Shell Mura is prevented from generating in the liquid crystal
