A beveling machine having a table provided with a plurality of fixing stands in tandem for fixing glass plates and a head stand carrying working heads equipped with working wheels rotatably in the same number as the fixing stands comprises means for causing the table and the working heads to conduct a relative movement in two directions in a horizontal plane, means for spinning the working wheels around a vertical axes. The relative movement of the table and the working heads in the two directions and the spinning movement of the working wheels around the vertical axes in the machine are controlled by a numerical control device in which the face of the glass plates to be ground and the grinding face of the grinding wheels are always kept at substantially a same contact angle.
