Embodiment 1

[0054] Take a large steel sheet with a thickness of 0.1 mm, cut it into several small steel sheets with a length of 3.14 mm and a width of 2 mm, and braze or electroplate diamond particles 1 on the small steel sheets to obtain a diamond substrate 5 . Such as Figure 1a As shown in , the diamond substrate 5 is composed of diamond particles 1 and small pieces of steel sheet 2 .

[0055] Select a multi-strand alloy steel wire rope 4 with a diameter of 1mm, coat the surface with epoxy resin after degreasing treatment, then coat the bottom surface of the prepared diamond substrate 5 (without diamond surface) with epoxy resin, and curl it into a It is cylindrical and bonded to the wire rope 4 at intervals of 5 mm.

[0056] After the glue is cured, evenly coat a layer of two-component polyurethane adhesive (flexible) on the alloy steel wire rope 4 bonded with the diamond substrate 5, and the polyurethane adhesive buries the steel wire rope 4 and the diamond substrate 5 except cutting...

Embodiment 2

[0060] Such as Figure 4 As shown in , take a large steel sheet with a thickness of 0.1 mm, cut it into several irregularly shaped small steel sheets with a length of 3 mm and a width of 0.8 mm, and braze or electroplate diamond particles 1 on the small steel sheets , obtain a diamond substrate 5, the diamond substrate 5 is composed of diamond particles 1 and a small piece of steel sheet 2.

[0061] Select a steel wire 4 with a square (side length of 0.8 mm) cross-section, and then spot-weld the prepared diamond substrate 5 to one of the steel wires 4 at intervals of 5 mm. on flat surface. After the welding is completed, the square steel wire rope welded with the diamond substrate 5 is twisted into a spiral shape. At this time, the diamond substrate 5 is distributed in each direction of the square steel wire rope.

[0062] Get the adhesive (flexible), which includes 89% polyurethane adhesive, 10% diamond powder (600 mesh) and 1% polyurethane fine fiber by weight percentage i...

Embodiment 3

[0066] The prepared length is 3mm, the width is 2mm, and the diamond substrate 5 with at least one diamond particle is brazed or electroplated for use. The diamond substrate 5 is made up of diamond particles 1 and small pieces of steel sheet 2, such as Figure 1a shown in .

[0067] Choose a multi-strand alloy steel wire rope 4 with a diameter of 1 mm. After surface degreasing treatment, the bottom surface of the prepared diamond substrate 5 (without diamond surface) is directly welded to each direction on the gold steel wire rope. Every two adjacent diamond substrates The interval between the sheets 5 is about 6 mm.

[0068] On the alloy steel wire rope 4 that is bonded with diamond substrate 5, evenly coat one deck of two-component polyurethane adhesive (flexibility), the polyurethane adhesive buryes the area other than the cutting surface on the steel wire rope 4 and the diamond substrate 5, After the above adhesive is completely cured, a polyurethane layer 3 is formed. In...

Abstract

The invention discloses a diamond wire saw, which comprises diamond grinding grains, a flaky base, a rubber plastic material layer and a center line positioned in the center of the rubber plastic material layer, wherein the diamond grinding grains are fixed on the flaky base, and the rubber plastic material layer covers all parts on the center line, the flaky base and the diamond grinding grains except cutting surfaces. The diamond wire saw has the advantages of simple manufacture process and low production cost and difficult falling of the diamond grinding grains in the wire saw in the cutting process.

Description

technical field [0001] The invention relates to a diamond tool, in particular to a diamond wire saw. Background technique [0002] As the hardest material, diamond is widely used in the processing of materials, especially the grinding and cutting of non-metallic brittle and hard materials, and is widely used in cutting tools such as diamond wire saws and diamond wire saws. Diamond wire saws are mostly used for crystal cutting, and their diameters are mostly within 1mm. The diamond wire saws used for crystal processing (obtained by depositing very fine diamonds on steel wires by electroplating) have small diameters, small slits, and have the ability to be cut. The material consumption and waste are small. However, because the diamond abrasive particles attached to the wire saw are small, the particle size is mostly below 0.1mm. Therefore, if it is used for stone cutting, the cutting efficiency is very low and cannot meet the requirements of production. need. At present, in ...
