preparation example Construction

[0029] The preparation method of the above-mentioned vitrified bond is to mix the above-mentioned raw materials evenly, melt at 1300°C for 100 minutes, water quench, crush, dry, and sieve to obtain a fine vitrified bond of 200 mesh or more.

[0030] The vitrified bond diamond grinding wheel provided by the present invention comprises a substrate and a grinding block. The raw material of the grinding block contains the above-mentioned vitrified bond, and also includes diamond abrasives and fillers. The vitrified bond, diamond abrasives and fillers are collectively referred to as powder crystals. The raw material of the grinding block can also include a pore-forming agent and a temporary bonding agent. The pore-forming agent and the temporary bonding agent are additional additives, which can be used as pore-forming and forming aids. Most of the time, the pore-forming agent is fired And the temporary binder will volatilize or burn away. The matrix may be a steel matrix, an aviati...

Embodiment 1

[0046] Raw material ratio of vitrified bond: SiO 2 : 40wt%, Al 2 o 3 : 12wt%, B 2 o 3 : 20wt%, Na 2 O: 10wt%, CaF 2 : 12wt%, Li 2 O: 5wt%, TiO 2 : 1wt%;

[0047] The preparation method of the above-mentioned vitrified bond: mix the above-mentioned raw materials evenly according to the proportion, then melt at 1300°C for 100 minutes, water quench, crush, dry, and sieve to obtain a vitrified bond with a particle size of no more than 75 μm (screened with a 200-mesh sieve) .

Embodiment 2

[0049] Raw material ratio of vitrified bond: SiO 2 : 45wt%, Al 2 o 3 : 9wt%, B 2 o 3 : 20wt%, Na 2 O: 8.5wt%, CaF 2 : 11wt%, Li 2 O: 5wt%, TiO 2 : 1.5wt%;

[0050] The preparation method of the above-mentioned vitrified bond is the same as in Example 1, and the particle size of the obtained vitrified bond is not greater than 75 μm.

[0051] Several examples of the vitrified bond diamond grinding wheel of the present invention and the preparation method thereof are enumerated below.

Abstract

The invention belongs to the field of grinding tools, and discloses a diamond grinding wheel and a preparation method thereof. The diamond grinding wheel comprises a base body and an abrasion block, and a raw material of the abrasion block contains a ceramic binding agent made of the follow raw materials: SiO2 of 40-46wt%, Al2O3 of 8-13%, B2O3 of 18-22%, Na2O of 8-10%, CaF2 of 11-15 wt%, Li2O of 4-6wt% and TiO2 of 1-2wt%. The diamond grinding wheel can effectively improve processing efficiency of gorilla glass, reduce processing cost, reduce pollution to environment, and meets the requirements for grinding and processing the gorilla glass. In addition, according to the diamond grinding wheel, firing temperature of a binding agent is low, holding force on an abrasion material is strong, damage on diamond is greatly reduced under a process system, and the grinding wheel does not need to be repaired in the grinding process.

Description

technical field [0001] The invention relates to the field of abrasive tools, in particular to a vitrified bond, a vitrified bonded diamond grinding wheel and a preparation method thereof. The vitrified bonded diamond grinding wheel of the present invention can be applied to high-hard metals and non-metallic hard materials that are difficult to process with ordinary material grinding wheels. Grinding of brittle materials, but mainly used in the grinding of diamond glass. Background technique [0002] Due to its wear resistance and high strength, diamond glass is widely used in the panels of communication terminals such as Iphone and Ipad. With the continuous development of processing technology, the application of diamond glass will become more and more extensive. [0003] In the past, free silicon carbide abrasives were mainly used to grind diamond glass, and its processing efficiency was extremely low. Manufacturers who ordered large quantities of grinding equipment still ...
