A dressing apparatus for a dished or plate-shaped grinding wheel of a tooth flank-grinding machine, comprising a dressing carriage or slide which can be radially advanced or fed by means of a radial drive in relation to the grinding wheel. The dressing carriage supports a dressing tool which serves for dressing the outer surface of the grinding wheel and a feeler which serves to scan the active end surface or rim of the grinding wheel. The feeler serves to control the axial advancing or infeed movement of the grinding wheel, and such feeler, during such advancing movement, always moves radially with respect to the grinding wheel. The dressing tool is arranged upon a tool support in off-set relation to the feeler in the peripheral or circumferential direction of the grinding wheel. The tool support is adjustably arranged at the dressing carriage or slide for movement essentially parallel to the active end surface or rim of the grinding wheel and is controlled by an auxiliary or additional drive which is connected with the radial drive.

Dressing apparatus for a dished grinding wheel at a tooth flank-grinding

An indexing generating method for grinding gears having an involute-shaped tooth flank profile, wherein there are accomplished between a dished or plate-shaped grinding wheel and the gear teeth to-and-fro generating movements as well as feed or advance movements in the tooth lengthwise direction, adjustment movements for compensating for the wear of the grinding wheel, and, finally, indexing movements. The grinding wheel is advanced between two respective indexing movements, independently of the magnitude of the adjustment needed for compensating for wear of the grinding wheel, by such an amount towards the tooth base or bottom land that also such tooth base is ground.
