Verfahren und Einrichtung zum Schleifen rillenförmiger Außenprofile eines Werkstückes

摘要

The invention concerns a method and device for simultaneously working different parts of the surface of one and the same workpiece using two abrasive wheels. The method calls first for the smooth-polishing positions of the two abrasive wheels (4.1; 4.2) to be calculated. When the two abrasive wheels (4.1; 4.2) have been brought into these positions, the abrasive wheels (4.1; 4.2) are shaped with a dressing tool (1), thus producing the surface roughness appropriate for rough-grinding. Subsequently, the abrasive wheels (4.1; 4.2) are brought into the calculated rough-grinding positions and the rough-grinding carried out. The abrasive wheels (4.1; 4.2) are then brought into the smooth-polishing positions. In the following dressing procedure, the surface roughness appropriate for smooth-polishing is produced. The smooth-polishing is then carried out. In the device proposed, the abrasive-wheel carriages (14.1; 14.2) are disposed such that the two abrasive wheels (4.1; 4.2) have a common axis of rotation (15). A rotating dressing tool (1) mounted on a device (16) which can move in two dimensions is disposed parallel to this axis (15). The dressing tool (1) can be used to shape all the parts of the abrasive-wheel surface. The surface thus produced is reproduced accurately on the workpiece (2).
