Problems solved by technology

During electroplating consolidation, this size difference will cause the position and flatness of the abrasive grains to be inconsistent, resulting in uneven distribution of the abrasive grains on the coating
This uneven distribution will reduce the grinding capacity and efficacy
[0004] In addition, because the abrasive grains are fixed on the metal substrate by electroplating, the geometric shape of the abrasive grains will produce a shielding effect during the electroplating process, so that the coating around the abrasive grains forms a concave surface, thereby reducing t

Example Embodiment

[0039] The detailed structure and manufacturing process of the present invention are further given through the following description.

[0040] Such as figure 1 As shown, the manufacturing steps of the present invention are: 1. Place abrasive grains on a substrate (Step 202), 2. Form a base layer to consolidate the abrasive grains on the substrate (Step 204). 3. A consolidation layer is formed on the base layer (step 206). 4. Remove the substrate (step 208). 5. Remove the base layer as appropriate (step 210), thereby forming a cutting abrasive sheet.

[0041] figure 2 It is used to illustrate the step of forming a base layer 24 to consolidate the abrasive grains 22 on the substrate 20. The abrasive particles 22 are made of materials with abrasive capabilities, such as materials such as diamond, boron nitride, and aluminum oxide. The material of the base layer 24 can be a polymer material, a metal, a metal compound, or a carbide, for example, iron, chromium, nickel, copper, zinc,...

Abstract

A cutting abrasive disk is composed of at least one solidified layer and a layer of abrasive particles embedded in said solidified layer. Its preparing process includes such steps as arranging the abrasive particles on a substrate, forming a basic layer on said substrate for binding said abrasive particles onto substrate, forming a solidifying layer, attaching at least one solidifying layer and one layer of abrasive particles, and removing substrate.

Description

1. Technical field [0001] The invention relates to a cutting abrasive sheet and a manufacturing method thereof. More specifically, the present invention is a cut-off abrasive sheet with a flat and contoured abrasive surface and a manufacturing method thereof. 2. Background technology [0002] With the development of modern industry towards high precision, the required grinding accuracy is also increasing when processing precision molds or components. [0003] In the existing cutting and abrasive sheets, the abrasive particles are consolidated on the metal base by means of a coating. The abrasive grains are screened before use, but there are still size differences. During electroplating consolidation, this size difference will cause the location and flatness of the abrasive grains to be inconsistent, resulting in uneven distribution of the abrasive grains on the coating. This uneven distribution will reduce grinding capacity and efficacy. [0004] In addition, because the...
