Abstract

The invention discloses a microcrystalline glass ceramic binding agent, a preparing method thereof, an SG grinding wheel and a preparing method thereof. The binding agent is prepared from, by weight percentage, 40% to 65% of SiO2, 6% to 20% of Al2O3, 5% to 18% of Na2O, 0.5% to 5% of CaO, 3% to 10% of K2O, 8% to 35% of B2O3, 0.5% to 2% of MgO and 2% to 6% of TiO2. The microcrystalline glass ceramic binding agent is formed by reasonably selecting the raw materials, the scientific ratio is adopted, the binding agent has the beneficial effects of being low in thermal expansion coefficient and crystallization temperature and high in strength accordingly, the microcrystalline glass ceramic binding agent is suitable for being used as a binding agent of the SG grinding wheel, the firing temperature of the SG grinding wheel is greatly reduced, and the firing time of the SG grinding wheel is greatly shortened; and meanwhile the work efficiency and the machining accuracy of the SG grinding wheel are improved, grinding heat is reduced, and the service life of the grinding wheel is prolonged.

Description

technical field [0001] The invention belongs to the field of abrasive materials, and in particular relates to a glass-ceramic bond and a preparation method thereof, an SG grinding wheel and a preparation method thereof. Background technique [0002] SG grinding wheel has good wear resistance, sharp abrasive grains, large feed rate, less grinding heat, strong burn resistance, long dressing cycle during grinding, small dressing amount, long service life, etc. It is often used in various profile grinding, cut-off and plunge-cut grinding, especially for gear grinding, lead screw grinding, thread grinding, worm grinding and grinding of various rolls and rubber rolls. [0003] SG abrasive, produced by seeding gel sintering process, is a revolutionary new generation of alumina abrasive, with a grain size several thousand times smaller than that of ordinary white corundum. A SG abrasive with a particle size of 60 mesh is actually Composed of millions of particles, it breaks along t...
