摘要：This apparatus has plural fixed grinding machines (10,11), which are installedalong the direction of travelling line of billets (1). And, facing pair of grinders (3,4) areequipped in a manner that the distances between each facing pair of grinders (3,4) aregradually shorter along the travelling direction of the billets (1) from the upstream sideto the downstream side. In such a multiple-stage grinding machine, the burr on thewelded part of the top and bottom side of the billet (1) are ground sequentially by thegrinders (3,4), and the burr on welded part of the right and left side of the billet areground sequencially by the grinders (3,4).
