Problems solved by technology

[0003] At present, there are cast-type diamond dry grinding discs for stone grinding, but they have the following problems: 1. The abrasive grains have low holding strength, and the abrasive grains fall off without being fully utilized; 2. The wear resistance of the abrasive discs The abrasiveness is poor, which leads to the low strength of the carcass in the dry grinding process of the grinding disc, and the diamond sinks, which does not give full play to its grinding use; 4. There are large pores on the surface of the dry grinding disc, and the large pores are uncontrollable. The method of vacuuming and defoaming is high in manufacturing cost and it is not easy to realize the temperature control of the mould.

Abstract

The invention discloses a pouring dry grinding piece material. The pouring dry grinding piece material comprises the following components, by mass, of 30%-40% of bonding agents, 10%-15% of diamond grinding materials, 5%-10% of silicon carbide, 5%-10% of white corundum, 20%-30% of fillers, 1%-5% of toughening agents, 0.5%-2% of coupling agents and 0.3%-1% of defoaming agents. The pouring dry grinding piece material has the advantages of high in grinding particle holding strength and good in heat resistance and abrasion resistance and is capable of improving the processing effect and reducing the processing cost.

Description

technical field [0001] The invention relates to the technical field of stone grinding and polishing, in particular to a diamond dry grinding disc with high abrasive holding strength, good wear resistance and good heat resistance. Background technique [0002] Casting dry grinding discs are mainly used for grinding and cutting stone cutting surfaces. The previous process is metal saw blades. After sawing, dry grinding discs can be directly used to polish and polish, so that the sawing surface and the surface have the same gloss. Dry grinding discs Grinding and polishing are no longer required after grinding. [0003] At present, there are cast-type diamond dry grinding discs for stone grinding, but they have the following problems: 1. The abrasive grains have low holding strength, and the abrasive grains fall off without being fully utilized; 2. The wear resistance of the abrasive discs The abrasiveness is poor, which leads to the low strength of the carcass in the dry grind...
