Embodiment Construction

[0015] Embodiment 1 of the present invention. A method for manufacturing a vitrified diamond composite grinding wheel, comprising the steps of:

[0016] a. By mass, mix and granulate 75-85 parts of diamond, 8-12 parts of silicon carbide and 4-6 parts of binder, then carry out compression molding, dry at 90-110°C for 4-6 hours, and then dry at 370 Pre-fire at -430°C for 1-3 hours, and then sinter at 800-900°C for 4-6 hours to obtain node units.

[0017] Mixing and granulation refers to adding diamond, silicon carbide and binder to 5% polyvinyl alcohol aqueous solution for wetting, then mechanically sieving and granulating.

[0018] The binding agent adopts the existing β-spodumene.

[0019] b. Process the grinding wheel base according to the existing process, put the node unit and the grinding wheel base into the mold, arrange a circle of node units outside the grinding wheel base, inject polyimide composite material between the node unit and the grinding wheel, and pass thro...

Abstract

The invention discloses a method for manufacturing a ceramic diamond composite grinding wheel, which is characterized by comprising the following steps of: by mass, mixing and pelletizing diamond, silicon carbide and a bonding agent, carrying out compression molding, drying, pre-burning and then sintering to obtain a joint unit; and placing the joint unit and a grinding wheel matrix into a die, pouring a polyimide composite material between the joint unit and the grinding wheel, carrying out pressing, then carrying out cooling and sintering to obtain the grinding wheel. According to the composite grinding wheel manufactured by the method disclosed by the invention, an integrated pressing sintering or embedding splicing mode is adopted; the polyimide composite material is used as a transition adhesive; and the integral grinding wheel is manufactured after carrying out secondary hot pressing and sintering. The chip accommodating and drainage space surface coverage rate of the ceramic diamond composite grinding wheel can reach 30 to 70 percent. The ceramic diamond composite grinding wheel has the following excellent grinding characteristics that the cutting depth is large; the grinding precision is high; in the forming and grinding process, the retentivity of a molded surface is good; the application range is wide; the grinding wheel can be used for dry grinding and has resistance to the high temperature of 350 DEG C and splicing units cannot fall off and blocks cannot fall off; and the grinding wheel has high revolving strength.

Description

technical field [0001] The invention relates to a manufacturing method of a vitrified diamond composite grinding wheel, which belongs to the technical field of grinding wheels. Background technique [0002] In the prior art, multi-node vitrified diamond (or cubic boron nitride CBN) composite grinding wheels have similar structures at home and abroad, but the combination of the node units and the grinding wheel base is a common adhesive bonding structure, which has poor corrosion resistance , and it will fail and fall off automatically over time, so it cannot be used for dry grinding at all, and its grinding performance is unreliable. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a vitrified diamond composite grinding wheel. High gyration strength, excellent grinding properties, long service life, can be used for dry grinding, high temperature resistance of 350 ℃, and the inlaid joint unit does not fall off,...
