ABSTRACT:
A deburring machine for plate- or sheet-like workpieces has a horizontal table on which a workpiece to be treated is supported during movement in parallelism with at least one of its elongated marginal portions. At least one set of coaxial cylindrical brushes is adjacent to the one marginal portion of the moving workpiece and the brushes form at least one pair of neighboring brushes which are driven to rotate in opposite directions whereby the metallic bristles of one brush treat the underside and the metallic bristles of the other brush treat the upper side of the one marginal portion. The frame of the machine can support two sets of coaxial brushes if the workpieces have parallel marginal portions. Such workpieces are advanced between the two sets of brushes so that one set treats one of the parallel marginal portions and the other set treats the other marginal portion. The brushes of each pair can be driven in opposite directions by a single motor and one or more transmissions which eceive torque from the motor or from one of the brushes if the one brush receives torque directly from the motor or from a shaft which is common to the brushes of a set and is or can be driven by the motor. Each set can be assembled of two or more pairs of neighboring brushes, and each marginal portion of a workpiece can be simultaneously treated by two sets of brushes which define a nip for entry of the marginal portion which requires deburring or an analogous treatment.
