Problems solved by technology

But it also has some disadvantages: due to the poor wear resistance of the copper-plated steel wire, the life of the steel wire is short
Moreover, the surface is smooth, and the ability to carry abrasives is poor. During cutting, the free blades are easy to slip with the steel wire, which makes the cutting speed and processing efficiency low.

Embodiment 1

[0020] A steel core wire free cutting wire, the preparation method of which is as follows: after coupling treatment of the surface-purified filler, mix it with a resin binder, then add a solvent and a curing agent, and mix evenly to obtain a slurry; then apply the slurry On the surface of the purified steel wire core wire, it is obtained after the diameter is limited and solidified, the details are as follows:

[0021] ①Steel wire purification treatment: A single stainless steel wire with a diameter of 0.1mm is degreased with 25wt% sodium hydroxide solution at 50~70°C. Sulfuric acid solution activated the surface for 5 minutes, washed with deionized water until neutral, and dried for later use.

[0022] ②Preparation of coating composite agent: The filler (the filler is composed of diamond micropowder, silicon carbide micropowder, aluminum oxide micropowder and copper powder) is treated with ultrasonic wave in acetone for 20 minutes (frequency 18 kHz) and then dried, followed b...

Embodiment 2

[0026] In this example, the difference from Example 1 is that the filler used is composed of diamond micropowder, copper powder, silicon carbide micropowder and aramid fiber chopped strands. The prepared slurry contains 2% diamond powder with a particle size of 0.5 microns, 8% silicon carbide powder with a diameter of 5 microns, 8% copper powder with a diameter of 2 microns and a volume content of 5% with a diameter of 5 microns. 1 mm aramid chopped strands.

[0027] The dicing wire produced had a diameter of 0.12 mm and a resin bond coating of about 10 microns.

Embodiment 3

[0029] In this embodiment, the difference from Embodiment 1 is that carbon steel wires are used instead of stainless steel wires.

[0030] The dicing wire produced had a diameter of 0.12 mm and a resin bond coating of about 10 microns.

Abstract

The invention relates to a steel core wire free cutting line. The steel core wire free cutting line comprises a steel core wire and a resin adhesive coating coated on the core wire; a resin adhesive used in the resin adhesive coating has the softening temperature of more than 150 DEG C; the coating contains filler fixed to the coating, wherein the diameter of the filler is smaller than the thickness of the coating; and the filler is micro-powder and / or a chopped wire, and the content of the filler is less than 65 percent of the volume of the coating. The cutting line is manufactured by coating the resin adhesive coating blended with the filler on the surface of the steel core wire. Compared with a copper plated steel wire, the cutting line has good abrasion resistance of the coating, particularly, the twisted multi-strand coating line has strong sanding capability due to rough surface; and when the cutting line is used for cutting and processing hard and brittle materials, the cuttingefficiency can be remarkably increased, the service life of the cutting line is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of cutting materials, and in particular relates to a cutting wire with a steel wire as a core wire and a resin binder coating on the surface and a preparation method thereof. This type of cutting wire is used for monocrystalline silicon, polycrystalline silicon, jade, sapphire , glass, quartz and other high hardness, high brittleness, high wear resistance materials cutting processing, with high efficiency, high life, high finish. Background technique [0002] Hard and brittle materials include gems, glass, stone, silicon crystals, quartz crystals, ceramics, hard alloys, etc. Hard and brittle materials are mostly semiconductors or non-conductors, with high hardness, high brittleness, high wear resistance, high resistivity and other properties. Hard and brittle materials are widely used in sound, light, electromagnetic, machinery and chemical industries because of their excellent properties that are incompara...
