A deburring method. An upper grinding head motor (11) drives an upper abrasive belt (7) into horizontal rotation by driving an upper active drum (6). A lower grinding head motor (20) drives a lower abrasive belt (4) into a horizontal rotation by driving a lower active drum. When a workpiece-to-be-deburred passes a passage constituted by an active feed roller row (14) and the upper abrasive belt (7), for each rotation by the upper abrasive belt (7), under the action of an upper abrasive pressure wheel set (17), an upper abrasive block (5) fixed on the upper abrasive belt (7), where the upper abrasive block (5) is flexibly in touch with a surface of the workpiece and is driven by the upper grinding head motor (11) and by the upper active drum (6), twice completes polishing and deburring of the obverse side of the workpiece, while at the same time, for each rotation by the lower abrasive belt (4) arranged beneath the workpiece and driven by the lower grinding head motor (20) and by the lower active drum, under the pressing action of a lower abrasive belt pressure wheel set (21), a lower abrasive block on the lower abrasive belt (4), where the lower abrasive block is flexibly in touch with a surface of the workpiece and is driven by the lower grinding head motor (20) and by the lower active drum, twice completes polishing and deburring of the reverse side of the workpiece. The method is simple and convenient to operate, of great reliability, and allows for improved deburring efficiency. Also disclosed are a deburring machine abrasive belt and a deburring machine that deburrs twice per rotation.
