PURPOSE:To enable efficient burr removal in a short time with the chamfering method and device, which removes burrs at the edge of metal parts etc., by furnishing a grinding member and a retaining plate with holes to retain a work rotatably. CONSTITUTION:A grinding member 1 provided with a grinding face 3 at the oversurface is rotated by a drive shaft 5 installed at the undersurface in its center. The oversurface is equipped with a retaining plate 7 having in the periphery a number of retaining holes 15 to retain a work 17, and is fixed to a fixation part 11 by a mounting piece 9 with the aid of screws 13. Here the grinding liquid supplied from a pump 29 through a supply pipe 27 is supplied to the work 1 from a plurality of through holes 23 provide at the inside of bosses 25, and burrs are ground off by contact frictions due to relative rotation. Because works 1 do not collide one another, their surfaces are free from risk of flaw to lead to efficient burr removal in a short period of time. |
