Abstract:
A machine for machining cylindrical surfaces of circular cylindrical parts by tangential movement over the cylindrical surface of a workpiece, in at least one machining station, of an abrasive belt which, fed from a pay-out spool, passes over a pressure roller before the abrasive belt is rewound onto a take-up spool, the workpiece being supported by a pair of spaced parallel support rollers, wherein said machine comprises a support assembly (12, 112) on which the support rollers (16, 116) are mounted so that they can rotate about their axis, a machining assembly (5, 105) carrying the machining station or stations (6, 106), one of said assemblies being mobile in translation parallel to the axis of the support rollers relative to the other assembly, means (4, 104) for rotating the rollers about their axis, and means (3, 103) for moving one of said assemblies in translation parallel to the axes of the support rollers relative to the other assembly,and wherein said machine comprises a plurality of successive machining stations (6, 106) in the translation direction.
