Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, and in particular relates to a grinding device for a hard alloy tool. Background Art

[0002] Carbide tools are a type of cutting tools. During their machining and manufacturing process, not only do they need to grind away the burrs on the tool surface to prevent the burrs from hurting the user, but they also need to sharpen the tool, that is, grind the blade. After a period of use, the blade will often become blunt or even curl due to excessive use. At this time, the blade needs to be re-grinded to ensure its normal use.

[0003] At present, most of the existing cemented carbide tool grinding devices do not have the function of adjusting the grinding angle during the grinding process. During the grinding process, the tool is fixed on the fixture, and the grinding disc is connected to the grinding motor, and only a fixed angle can be formed between the two, making it difficult to adjust the angle of the fixture. For this reason, we propose a cemented carbide tool grinding device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
