Problems solved by technology

[0002] In ceramic and stone processing occasions, ordinary silicon carbide grinding wheels are commonly used for processing. The grinding wheels of this material are cheap and the technology is relatively mature, but there are also many disadvantages, such as high temperature is easy to produce black cores, short service life, and low processing accuracy. , more energy consumption, etc.
In recent years, diamond grinding wheels have gradually begun to replace silicon carbide grinding wheels, and resin-bonded grinding wheels are generally made of diamond grinding wheels, but the grinding efficiency of resin-bonded grinding wheels is low, and deformation is easy to occur during the grinding process
The ceramic grinding wheel has sufficient hardness, but its toughness is poor, and it is easy to break during use.

Abstract

The invention discloses a self-lubricating diamond resin vitrified grinding wheel. A grinding block comprises the following components in percent by mass: 45-55 percent of a diamond abrasive, 30-45 percent of a resin bond, 18-30 percent of a vitrified bond and 0-2 percent of a solid lubricant. The resin bond is polyimide resin powder. The vitrified bond comprises the following raw materials in percent by weight: 45-47 percent of SiO2, 21-33 percent of B2O3, 5-13 percent of K2O, 3-6 percent of Bi2O3, 2-5 percent of SnO2, and 2-6 percent of Sb2O3. The sintering temperature of the bond is 750-820 DEG C, the abrasive holding force is strong, damage to used diamond is greatly reduced under the design technology system, and the grinding wheel does not need to be finished during the grinding process. The solid lubricant is added, so that the self-lubricating diamond resin vitrified grinding wheel is self-lubricated during the grinding process.
