Abstract
Machine for machining using abrasive belts circular workpieces supported by at least one pair of parallel rollers. To pass the workpieces under the machining station(s) 6, the support rollers 16 driven in rotation are moved in translation parallel to their axes. The rollers 16 are preferably mounted on a table 13 mobile in translation which can also carry means 19 for positioning the workpieces to be machined.
Claims10
A machine for machining, in particular superfinishing, 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 it is rewound onto a take-up spool, the workpiece being supported by a pair of spaced parallel support rollers, characterised in that it 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 axes 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.
A machine according to any one of the preceding claims characterised in that the mobile assembly (12, 105) is moved in translation by a screw nut drive system (3, 4, 103).
A machine according to any one of the preceding claims characterised in that it comprises a plurality of successive machining stations (6, 106) in the translation direction.
