Embodiment Construction

[0038] Please check figure 1 , figure 2 and image 3 , an orderly arranged diamond grinding disc, including a base disc 1 and several grinding discs 2 . Each of the grinding discs 2 includes several gel grinding rods 3 containing diamond abrasive grains, several gel grinding rods 4 not containing diamond grinding grains, and epoxy resin 5 used as a bonding agent. In this embodiment: epoxy resin is selected as the binding agent, but it is not limited to this, and any one of phenolic resin, polyimide resin, photocurable resin, thermosetting resin, etc. can also be selected as required. Mixing of the above several kinds; the abrasive grains are selected from diamond abrasive grains, but not limited to this, and any one of CBN, alumina, silicon carbide, etc., or a mixture of the above-mentioned types can also be selected as required.

[0039] The gel grinding rods 3 containing diamond abrasive grains and the gel grinding rods 4 not containing diamond grinding grains are arrang...

Abstract

The invention discloses a grinding disc arranged in order and a preparation method thereof. The grinding disc comprises a base disc (1) and multiple grinding pieces (2). The multiple grinding pieces (2) are fixedly connected to the base disc (1). Each grinding piece (2) comprises multiple gel grinding rods (3), a binding agent (5) and multiple gel rods (4) containing no grinding particle. Each gel grinding rod (3) contains grinding particles (7). The multiple gel grinding rods (3) and the multiple gel rods (4) are fixed into a whole through the corresponding binding agent (5). The gel grinding rods (3) are used for achieving grinding processing. After the gel rods (4) are hydrolyzed, containing cavities can be formed. The grinding disc has the beneficial effects that the gel rods do not contain grinding particles; after the gel rods are hydrolyzed, the containing cavities can be formed, so that concave pits are formed, and a great number of containing spaces are formed in the surface of the grinding disc; and therefore, the problems that existing fine grinding tools are insufficient in scrap containing space and easy to block are solved.

Description

technical field [0001] The invention relates to an orderly arranged grinding disc and a preparation method thereof. Background technique [0002] Engineering ceramics, optical glass, artificial crystal and other hard and brittle materials are widely used in national defense, aerospace and other precision engineering fields due to their high hardness, good chemical stability, not easy to oxidize, wear resistance, high temperature resistance, corrosion resistance and other advantages. . In these applications, the workpiece is required not only to have high shape accuracy, but also to have high machined surface quality. However, these hard and brittle materials are very difficult to machine due to their extremely high hardness and great brittleness. [0003] Grinding as a precision machining method is widely used for precision machining of hard and brittle materials. So as to achieve the purpose of grinding material. In order to obtain a more precise machined surface and red...
