Problems solved by technology

[0006] 3. Single crystal corundum abrasive, its particles are composed of a single crystal, and has a good multi-edged cutting edge, high hardness and toughness, strong grinding ability, and low grinding calorific value. The disadvantage is that the production cost is high and the output lower, so the price is higher

Abstract

The invention discloses a composite cutting abrasive and grinding tool and a manufacturing process thereof. The composite cutting abrasive and grinding tool comprises the following raw materials in parts by weight: 50-70 parts of brown fused alumina, 10-20 parts of white corundum, 4-8 parts of green silicon carbide, 4-8 parts of black silicon carbide, 3-5 parts of cryolite, 5-8 parts of iron sulfide, 7-11 parts of chromium fused alumina, 8-15 parts of fused alumina zirconia, 4-7 parts of phenolic aldehyde and 5-9 parts of naphthamine. The manufacturing process of the composite cutting abrasive and grinding tool comprises the following steps: weighing the raw materials and then uniformly mixing; placing the mixed raw materials in a press to perform high-pressure treatment at 500 MPa to obtain a semi-finished product; measuring the mass of the semi-finished product to guarantee that the mass error is smaller than or equal to 2 g; placing the qualified semi-finished product in an electric furnace, and performing constant temperature treatment under the condition of 20-220 DEG C for 19-20 h to obtain the finished product. The manufacturing process is simple, high in efficiency, environment-friendly and pollution-free; the product is stable in quality, and the service life reaches up to 10 years.

Description

technical field [0001] The invention belongs to the technical field of abrasive tools and abrasives, in particular to a composite cutting abrasive and a manufacturing process thereof. Background technique [0002] Abrasives are a general term for abrasives and abrasive tools, including abrasive products and abrasive products. Abrasives are known as industrial teeth. Abrasives or grinding tools are often used as grinding tools in grinding to machine parts to be processed to meet certain technical requirements. [0003] Among them, abrasive products are mainly divided into two categories: corundum abrasive and silicon carbide abrasive. Specifically, there are basically the following types: [0004] 1. Brown corundum abrasive, the main component is Al2O3, which has medium hardness, high toughness, sharp particles, relatively low price, and is suitable for processing metals with high tensile strength. Both microcrystalline corundum abrasive and black corundum abrasive are its...
