    摘要: A balance arm for flat weighing machines has a rigid frame formed by girder-section rails extending between side beams. A pair of knife-edges are attached to each rail to extend parallel to the longitudinal axis thereof with the sharp edges of each pair of knife-edges in alignment. The rails are secured to the side beams such that all the sharp edges lie in a common plane. The configuration of the rails enables all the knife-edges to be precision ground on a common grinding machine after attachment to the inside of the rails and before the side beams are attached to the rails.
