Claims

[Scope of utility model registration request]

An iron-based dressing roll, a rotation drive device for the dressing roll, and a grindstone and dressing roll that enable grinding of the surrounding surface of the dressing roll using the surrounding surface of the grinding wheel, that is, dressing of the surrounding surface of the grinding wheel. The feeding device, which performs relative movement between At a second dressing speed where the dressing efficiency is less than half of that of the first dressing speed,
and a numerical control device that controls the feeding device so as to perform dressing of less than half of the machining amount at a second dressing speed, and to separate the grindstone and the dressing roll from each other after finishing the dressing at the second dressing speed. Dressing device for ultra-hard abrasive grinding wheels.
