Embodiment 1

[0018] The vitrified diamond grinding wheel is made of the following raw materials in parts by weight: diamond abrasive 50, chrome corundum abrasive 12, scrap steel powder 5, walnut shell grain 1.4, polyamide wax micropowder 2.2, trioctyl trimellitate 1.2, bentonite 2, dolomite 2. Black manganese ore 3. Quartz sand 3. Scrap iron powder 2.1. The bentonite, dolomite, black manganese ore, quartz sand, and scrap iron powder are smelted at a high temperature of 2687° C., cooled, and then ball-milled into nano-ceramic powder to become a vitrified bond.

[0019] The preparation method of vitrified diamond grinding wheel comprises the following steps:

[0020] (1) Put each component into the mixer according to the above formula, mix for 1 hour, and mix well;

[0021] (2) Pour the mixture into the mold, then put the mold into the press for pressing, and heat the mold at the same time, pre-pressurize 1 MPa, heat the upper and lower plates of the press at 300°C for 2 minutes...

Abstract

The invention discloses a ceramic diamond grinding wheel. The ceramic diamond grinding wheel consists of the following components in parts by weight: 50-60 parts of diamond grinding materials, 10-20 parts of rubing grain grinding materials, 4-8 parts of steel scraps powders, 1-3 parts of walnut shell grains, 2-3 parts of polyamide wax micro powders, 1-2 parts of trioctyl trimellitate, 2-5 parts of bentonite, 2-5 parts of dolomite, 3-6 parts of hausmannite, 2-5 parts of quartz sands and 2-3 parts of scrap iron powders. According to the ceramic diamond grinding wheel, a binding agent adopts ceramic materials, the grinding wheel is not easy to deform, good in heat resistance and has extremely high wear resistance; the adhesion of various ceramic materials is good, so that the cracking is prevented effectively, and problems that a conventional grinding wheel is poor in heat resistance and easy to deform can be solved. The problems that the conventional grinding wheel is not good in adhesion and the grinding wheels fall off easily can be solved. Due to the addition of metal powders, namely the scrap iron powders, the heat conduction property of the grinding wheel is improved, the heat dissipation is rapid, the grinding temperature is low, furthermore, the rigidity and the strength of the grinding wheel are improved, the cracks caused by rigid grinding are reduced, the grinding efficiency and the service life of the ceramic diamond grinding wheel are superior to those of a conventional grinding wheel, and the comprehensive benefits are improved by more than 50%.

Description

technical field [0001] The invention discloses a vitrified diamond grinding wheel and a preparation method thereof, belonging to the technical field of grinding tool processing. Background technique [0002] Grinding wheel is the most important type of abrasive tool in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing and Fine grinding as well as grooving and parting off etc. The substance used to bond the abrasive in the grinding wheel is called a bonding agent. The performance of the bonding agent determines the strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel. At present, the bonding agent is mainly divided into four types: ceramic, resin, rubber and metal, among which the ceramic bonding agent has good he...
