Description

Technical Field

[0001] The invention belongs to the technical field of electroplated diamond tools, and in particular relates to a method for manufacturing orderly arranged electroplated diamond tools. Background Art

[0002] Electroplated diamond tools refer to a type of tool formed by consolidating diamonds on a metal substrate with a certain shape by metal electrodeposition. It has the characteristics of simple process, high diamond edge, and sharp cutting (grinding). However, due to the dense diamonds in the tool and the small chip space, it is not easy to remove chips, resulting in high cutting (grinding) temperature and affecting the quality of the processed products. In order to solve this problem, the diamond density is reduced, and the diamonds are arranged in an orderly manner according to a certain pattern to increase the chip space between diamonds, so as to take away the cutting (grinding) heat in time and reduce the cutting (grinding) temperature to improve the processing quality. At present, the method of making diamonds in an orderly arrangement in electroplated diamond tools is to use an insulating single-sided adhesive to punch holes in a certain pattern with a punch (or drill press), and then tear off the single-sided adhesive and stick it on the metal substrate of the tool. The places with holes can be plated with nickel and diamonds, and the places without holes cannot be insulated and cannot be plated with nickel and diamonds. After plating, tear off the insulating adhesive to obtain an electroplated diamond tool with diamonds in an orderly manner in a certain shape.

[0003] According to the above-mentioned production method, since the diameter of the punch of the punch machine or the drill bit of the drilling machine can only be at least 0.5mm, and the density of the punching (drilling) cannot be too high, the diamonds cannot be arranged in an orderly manner one by one, but are arranged in an orderly manner piece by piece. This still cannot meet the requirements of some very demanding use environments (such as grinding of space lenses, etc.). In order to solve this problem and realize the orderly arrangement of diamonds one by one, the present invention proposes a method for producing an orderly arranged electroplated diamond tool. Summary of the invention

[0004] The object of the present invention is to provide a method for manufacturing orderly arranged electroplated diamond tools to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for manufacturing an orderly arranged electroplated diamond tool, the specific steps comprising: S1: firstly coating or spraying a layer of UV light-cured insulating ink on a metal substrate of the tool, and then placing it under UV light irradiation for hardening;

[0006] S2: After the ink is hardened, use CO 2 The laser punches small holes in the ink one by one according to the pattern arrangement, and the diameter of the small hole is determined by the size of the diamond straight hole;

[0007] S3: Diamonds are plated into each small hole one by one by electroplating;

[0008] S4: After removing the insulating ink layer with alkaline solution, an electroplated diamond tool with orderly diamond arrangement can be obtained.

[0009] Preferably, in S1, the thickness of the coated UV light-curable insulating ink layer is 0.3-0.6 mm.

[0010] Preferably, in S1, the insulating ink layer is photocured by UV light with a wavelength of 200-400nm at a temperature of 25-45°C, the irradiation time is controlled to be 3-8min, and the light brightness during curing is controlled to be 1000-3000mj / cm 2 .
