Problems solved by technology

This existing manufacturing method is quite complicated, and the manufacturing cost of product is high
[0004] If electroformed diamond grinding wheels or metal sintered diamond grinding wheels are used, electric sparks are needed to trim the outer circumference of the two diamond grinding wheels into a special-shaped surface; moreover, these two kinds of diamond special-shaped grinding wheels do not have polishing functions and cannot be used to align waistlines. Polishing, and the production cost of these two kinds of diamond grinding wheels is also very high

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] see Figure 1-Figure 10 , the resin diamond abrasive tool comprises a matrix 1 and an abrasive layer 2, and the abrasive layer 2 is formed by mixing and casting a binder, an abrasive and a filler; wherein, the binder is composed of a phenolic epoxy vinyl ester resin solution, an initiator and a promoter The abrasive material includes diamond and silicon carbide. The weight ratio of the above components is: 100 parts of novolac epoxy vinyl ester resin solution, 2 to 3 parts of initiator, 1 to 4 parts of accelerator, and 10 parts of diamond ~20 parts, silicon carbide 10~30 parts, filler 80~120 parts.

[0029] The filler in this embodiment is any one or a combination of any two or more of alumina powder, quartz powder and cerium oxide polishing powder; the initiator can use ketone peroxide, here methyl ethyl ketone peroxide can be selected; the acc...

Abstract

The invention discloses a resin-bonded diamond abrasive tool, a method and a mold for producing the resin-bonded diamond abrasive tool. The resin-bonded diamond abrasive tool comprises a matrix and an abrasive layer, and the abrasive layer is prepared from binder, abrasive and packing by way of mixed casting, wherein the binder is prepared from epoxy novalac type vinyl ester resin liquid, initiating agent and accelerating agent through mixing; the abrasive comprises diamond and silicon carbide; and the packing is one or more of powdered alumina, quartz powder and cerium oxide polishing powder; and the components above in parts by weight are as follows: 100 parts of epoxy novalac type vinyl ester resin liquid, 2 to 3 parts of initiating agent, 1 to 4 parts of accelerating agent, 10 to 20 parts of diamond, 10 to 30 parts of silicon carbide, and 80 to 120 parts of packing. The invention has the advantages of good sharpness, strong self-sharpness, good grinding and polishing effects, simple and reasonable manufacturing process, precise one-stop special-shaped surface production, high grinding and polishing efficiencies, high comprehensive performance, and low production cost, and is flexible in operation,.

Description

technical field [0001] The invention relates to a resin diamond grinding tool, a manufacturing method thereof and a manufacturing mold. Background technique [0002] At present, it is more and more common to make waistlines with special-shaped surfaces from materials such as ceramics, stone, glass, and resin. The more common method is to cut ceramic polished tiles into strips, and then use a grinding wheel with the same grinding surface as the special-shaped surface. Grind and polish it into shape. [0003] Waist line is a kind of architectural decoration method, which generally refers to the decorative line on the surface of the building. Because the special-shaped surface of the waistline is relatively wide, generally more than 40mm, if the resin bonded with diamond grinding wheel formed by hot molding such as phenolic resin powder is used to grind and polish the special-shaped surface of the waistline. The two sides are relatively strong, while the middle is relatively ...
