Abstract

A gearlike tool for dressing abrasive, gearlike, tools used for precision machining gear workpieces has tooth flanks which are coated with diamond grains. The gaps between teeth of the base member which has the diamond coating are enlarged, for example by removing teeth, in order to make the application of the coating easier. In order to assure a fully meshing engagement, the dressing tool can be combined with uncoated guide wheels which have teeth which meshingly engage the teeth of the precision machining tool.
