▎ 摘　　要

NOVELTY - A graphene composite binding agent-based porous cubic boron nitride grinding wheel working layer comprises 15-20 mass% cubic boron nitride abrasive grains, 5 mass% graphene particles, 15-20 mass% ammonium bicarbonate particles and 55-65 mass% copper-tin-titanium composite solder. USE - Graphene composite binding agent-based porous cubic boron nitride grinding wheel working layer. ADVANTAGE - The working layer has high porosity, high strength, better water permeability and better thermal conduction properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene composite binding agent-based porous cubic boron nitride grinding wheel working layer.
