Specifically, the invention ensures that the dust really achieves the effect of zero emission through the combination modes of collecting and filtering the polishing dust, back blowing and circulating and filtering tail gas, turbulent treatment on the grinding wheel and the like. The technical characteristics of the structure can be applied to manual polishing and polishing machines, artificial intelligent automatic polishing and polishing machines and all the devices in various fields which generate raise dust and need dust collection and treatment. Therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
