Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheels, and particularly relates to a burr electric grinding wheel. Background Technique

[0002] An electric grinding wheel is a device used for grinding tools or cutters, and is also used for grinding, deburring, and cleaning of ordinary small parts.

[0003] For some burr electric grinding wheels in the prior art, a protective housing is provided on the outer periphery of the grinding wheel to prevent debris from splashing during the process of the grinding wheel grinding the tool. However, part of the grinding wheel is still exposed to the outside for grinding. Therefore, in order to ensure the safety of the operator, the operator is required to wear safety glasses to avoid damage to the operator by the debris. However, during the actual operation, there are still operators who do not choose to wear safety glasses because: the safety glasses will tighten the face during use, which is quite uncomfortable, and when used in winter, the side of the safety glasses close to the face has a higher temperature, while the side far from the face has a lower temperature, and it is easy to have the phenomenon of "fogging", which is not conducive to use, and the debris falling into the protective housing is not easy to take out and clean. Based on this, a burr electric grinding wheel is designed. Content of the Utility Model
