Problems solved by technology
[0002] As a grinding tool, the grinding wheel is widely used in precision machining and other fields. However, with the use of the grinding wheel, the grinding wheel itself will also wear out, which requires dressing the grinding wheel. The currently used dressing method is mainly to remove the grinding wheel from the processing machine tool This traditional method has the following defects: waste of time and materials, and in addition, the processing discontinuity caused by dressing the grinding wheel seriously affects the accuracy of the grinding wheel in precision machining.
