The method comprises the following steps: wiping oil stain on the roller head base by using a piece of clean cloth; slightly wiping outer contour surfaces of the roller head base by using oilstone of #220 in granularity, cutting high points to be flat or slightly concave by using oilstone or a scraper; placing the roller head base on a wiped plate, slightly, without collision; checking the perpendicularity of adjacent outer contour surfaces around by using a square ruler, wherein the perpendicularity is not greater than 0.02mm; checking the parallelism of the outer contour surfaces by using a dial gauge, wherein the parallelism is not greater than 0.01mm; moving a parallel gauge base with the clamped dial gauge to the roller head base, enabling a dial gauge testing head to contact the surfaces, moving the pointer of the dial gauge away from an initial position for 20 scales, moving the dial gauge base, and observing value variations of the pointer of the dial gauge at different testing points on a tested surface, wherein the variations should not be greater than 0.01mm. The method is simple to operate, convenient to check and capable of ensuring accurate inspection results.
