Abstract

The invention discloses a method used for detecting holding force of a ceramic binder on abrasive particles, and belongs to the technical field of super hard material abrasive material abrasive tool and ceramic binder super hard material product. The method comprises following main steps: the ceramic binder is mixed with an abrasive material, and an mixture is prepared into a block-shaped sample strip; the block-shaped sample strip is conveyed onto a grinding machine for grinding so as to exposure abrasive particles; a torsion tester is used for torsion test of the block-shaped sample strip with exposed abrasive particles so as to obtain the maximum torsion force value used for realizing shedding of the abrasive particles from the ceramic binder, wherein the maximum torsion force value is the holding force of the ceramic binder on the abrasive particles. The beneficial effects are that: the torsion tester is adopted to detect the torsion force value, and the torsion force value is used for representing the holding capacity, so that a difficult problem that direction measuring of holding force is impossible to realize is solved; the torsion tester is a digital display torsion tester, so that error caused by manual reading is avoided, and measurement is more accurate; the torsion force is used for qualitative analysis of holding capacity, and novel theoretical foundation is provided for manufacturing ceramic binder abrasive tools.

Description

technical field [0001] The patent of the present invention relates to the technical field of abrasives and vitrified bond products, in particular to a method for detecting the gripping force of vitrified bond on abrasive grains. Background technique [0002] The holding force refers to the physical adhesion, mechanical mosaic force and chemical force of the bond to the diamond abrasive grains in the diamond tool to ensure that the diamond abrasive grains can be firmly bonded without falling off. The service life and performance of vitrified bond diamond tools mainly depend on the ability of vitrified bond to hold diamond, so improving the interface bonding effect between vitrified bond and superhard material and improving the holding force between the two have a great impact on ceramic bonding. The application and development of agent superhard material products are of great significance. [0003] When ensuring sufficient strength of the binding agent, the chemical bonding ...
