Description

Technical Field

[0001] The utility model belongs to the technical field of grinding machines, and in particular relates to a protective device for a grinding machine. Background Art

[0002] A grinding machine is a common device used to sharpen various knives and tools. It is also used for grinding, deburring and cleaning ordinary small parts. It is mainly composed of a base, a grinding wheel, an electric motor or other power source, a bracket, a protective cover and a water supply. It can be divided into a handheld grinder, a vertical grinder, a hanging grinder, a desktop grinder, etc. A grinding machine is a mechanical processing tool that is used in many industries. For example, during the machining process, if the tool becomes blunt due to wear or damage and loses its cutting ability, the tool must be sharpened on the grinding wheel to restore its cutting ability.

[0003] When the existing hand-held grinder is in use, the grinding wheel rotates at high speed and generates a large amount of debris. Since the protective measures of the hand-held grinder are poor, the debris is easily splashed, affecting the use of the operator. Utility Model Content
