Embodiment Construction

[0011] The embodiment is an electroplated diamond grinding disc whose outer ring surface is a coarse-grained diamond abrasive layer and whose inner ring surface is a fine-grained diamond abrasive layer.

[0012] In order to manufacture the above-mentioned electroplated diamond grinding disc, the process includes bottom nickel plating, diamond abrasive layer, cleaning and other processes, which is characterized in that the process of upper diamond abrasive layer adopts partial covering and partial electroplating, that is, the fine-grained diamond abrasive is first covered On the first part, coarse-grained diamond abrasives are applied; then the cover is removed, and fine-grained diamond abrasives are applied; two diamond abrasive layers of different particle sizes are plated on the base of the grinding disc steel sheet. This process not only ensures that the coarse-grained diamond will not be mixed into the fine-grained diamond abrasive layer, but also ensures that the working s...

Abstract

An electroplated abrasive diamond disc is composed of a steel disc as basic body and with central axle hole, an electroplated abrasive diamond particle layer on the external ring on steel disc and an electroplated abrasive diamond particle layer on the internal ring on steel disc. The diamond particles for external and internal rings have different granularities. Its preparing process includes such steps as plating Ni layer on steel disc, shielding internal ring, plating coarse diamond particles onto external ring, removing the shielding layer, plating fine diamond particles onto internal ring, and cleaning.

Description

1. Technical field [0001] The invention relates to a grinding disc and its manufacturing process, in particular to an electroplated diamond grinding disc and its manufacturing process. The electroplated diamond grinding disc is a tool for grinding and polishing natural gemstones, artificial gemstones, glass products, tungsten steel products or the like . 2. Background technology [0002] At present, in gemstone processing and production, most of the electroplated diamond grinding discs used are one grinding disc with one diamond grain size. When forming and faceting gemstones, first use a coarse-grained diamond grinding disc (diamond grain size of 500 to 10 microns) to roughly grind the facets until roughly shaped; then use a fine-grained diamond grinding disc (diamond grain size of 50 to 0.5 microns), Carry out fine grinding and faceting to shape; then according to different gem materials, choose different polishing materials for polishing. Whether it is red sapphire, cry...
