Cutting grinding sheet and its manufacturing method

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...

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 the distance between the abrasive grains and the coating. Consolidation strength

In order to have a proper bonding strength between the abrasive grains and the coating, the required thickness of the coating is about 70% of the abrasive grains, so only about 30% of the abrasive grains can be used, which will reduce the usable abrasive grains part

[0005] In addition, the abrasive grains in the existing cutting abrasive sheets are generally arranged in a single layer, so when the single layer of abrasive grains is worn away, the life of the cutting abrasive sheet is also over.
