Description

Technical Field

[0001] The utility model relates to the technical field of grinding tests, in particular to a rapid clamping grinding test device for a diamond burr. Background Technique

[0002] At present, in the process of cleaning grooves or treating texture structures in oral teeth, dental burs are required. The rotation of the dental burs is driven by a handpiece, and path-moving grinding is performed. Multiple cutting edge structures are arranged on the surface of the existing dental burs. In order to further improve the service life of the dental burs, diamond is attached to the surface of the dental burs to improve their grinding ability and grinding quality. However, since the combination of diamond is likely to fall off during use, in order to detect the peeling force, a bonding test needs to be carried out. Currently, it is all judged through actual use and experience. The stability of the adhesion of diamond on the dental burs is judged as a whole, with low overall judgment efficiency and poor accuracy. There are also mechanical structures used for testing, but they cannot test dental burs with different structural forms and are not universal, and the test models are single.
