Abstract
In a process and apparatus for tooth-flank grinding of gearwheels, the opposing flanks of two adjacent teeth are initially ground simultaneously. In the terminal stages of the process, each flank is ground separately. A slight rocking motion of the gearwheel, provided by pivoted pawl in an indexing wheel, applies the grinding tool first to one tooth flank and then to the other. Any undesirable rounding off of the tooth flanks occurring during simultaneous tooth flank grinding can thus be corrected.
