Abstract

Ceramic organic composite binder for cubic boron nitride grinding wheels comprises 20-50% of AlPO4, 5-15% of SaO2, 5-30% of potassium feldspar, 5-15% of soda feldspar, 2-10% of TiO2, 15-20% of boric acid, and 5-20% of SiO2. The ceramic organic composite binder is improved in terms of wear resistance, burn prevention, shape stability maintenance and the like, and macro-performance of the binder is improved.

Description

technical field [0001] The invention relates to a ceramic organic composite binder used for cubic boron nitride grinding wheels, which can be used to make CBN grinding wheels and belongs to the technical field of binder materials. Background technique [0002] The grinding wheel is composed of three basic factors: abrasive grains, bonding agent and pores. The abrasive grains mainly play the role of cutting, and the pores mainly play the role of chip removal and cooling. The main functions of the bonding agent are: 1. Bond the abrasive grains together to make 2. After the grinding wheel is consolidated, it can withstand a certain grinding force and rotary tangential stress, and has sufficient rotary strength; 3. After the surface abrasive grains are blunted, they can be produced by external forces. Automatic shedding ability, that is, it can be made into various hardness, and it will produce self-sharpening effect when working. Therefore, the choice of bonding agent has a cr...
