The diamond grinding wheel is installed on the main shaft, and the main shaft rotates under the control of the controller to drive the diamond grinding wheel to rotate; the dressing distance fine-tuning system supports the electrolyte tank and finely tunes the height of the electrolyte tank. The utility model has high dressing efficiency and good protrusion of abrasive grains on the grinding wheel surface; by adjusting the grinding wheel speed, electrolytic voltage or current, and the distance between the dressing head and the grinding wheel surface, rapid dressing and precision dressing of the grinding wheel can be realized, which not only ensures good protrusion of abrasive grains, but also ensures strong holding force of the binder for the abrasive grains.

[0004] The existing off-line electrolytic dressing device for grinding wheels needs to install the grinding wheel to be dressed in a protective cover, and the protective cover is used for protection during dressing. During installation, the protective cover is generally inserted into the protective cover from one side of the protective cover, and the grinding wheel is installed in the protective cover through a limiting rod. However, this installation method requires manual support for the grinding wheel all the time, and the support force for the grinding wheel can be removed only after the installation is completed, which increases the work burden.
