Dressing equipment for non-conductive grinding wheel

The invention relates to dressing equipment for a non-conductive grinding wheel. The dressing equipment for the non-conductive grinding wheel comprises a main shaft, a workbench, an electrode and non-conductive grinding wheel mounting shaft, wherein the main shaft is used for mounting a conductive grinding tool; the workbench has at least transverse and longitudinal relative degrees of freedom tothe main shaft; the electrode is mounted on the workbench for dressing the grinding tool in an electric spark dressing manner; and the non-conductive grinding wheel mounting shaft is mounted on the workbench through a corresponding shaft seat and parallel to the main shaft. When the dressing equipment is used, through the relative movement of the workbench and the main shaft, the electrode is enabled to dress the grinding tool in the electric spark manner, and then the grinding tool is enabled to carry out grinding machining on the non-conductive grinding wheel; the grinding tool is dressed bythe electrode on line, so
