The invention discloses a micron-sized guide pillar hole machining device and method. The micron-sized guide pillar hole machining device comprises a machine base, a machining power head is installed on the machine base, a fixing block is fixed to the bottom of the machining power head, a sliding block is installed on the lower end face of the fixing block, the sliding block is slidably connected with the fixing block, a rotating sleeve is installed on the lower end face of the sliding block, the rotating sleeve is rotatably connected with the sliding block, and a grinding roller is mounted at the bottom of the rotating sleeve and is in sliding connection with the rotating sleeve. The micron-sized guide pillar hole machining device and method have the beneficial effects that the size error of a guide pillar hole can be controlled to be +/-0.001 mm, so that the precision of the guide pillar hole is improved, the positioning precision of other machining processes is greatly improved, and the smaller the eccentr
