Problems solved by technology

[0006] Although this prior art has slightly improved the performance of the abrasive carrier, it usually takes a lot of time to change the outer surface of the cutting wire, which reduces the manufacturing process and increases the production cost, and the performance of the abrasive carrier will also decline with the use process.

Embodiment 1

[0056] A wire rod with a carbon content of 0.70-1.05% and a diameter of 5.5 mm is drawn twice, then heat-treated and brass-plated, and finally drawn to a diameter of 0.100 mm to prepare a monofilament steel wire. Next, using a corrugation device, corrugations were provided on two planes of the monofilament-type steel wire that was finally drawn and not provided with corrugations, and εx P was 0.1, and εx d was 0.15h to produce a corrugated monofilament-type steel wire for cutting. The obtained corrugated monofilament steel wire for cutting was evaluated for its wire diameter, corrugation period, elongation, and elongation at break, and the results are shown in Table 1 below.

[0057] On the other hand, after cutting a silicon ingot with a diameter of 150 mm using a slurry made of silicon carbide, the physical properties and productivity of the wafer were evaluated by the following methods and the results are listed in the following table 1.

Embodiment 2

[0064] When drawing a wire rod with a carbon content of 0.70 to 1.05% and a diameter of 5.5mm, heat treatment and brass plating are performed twice, and finally drawn to 0.115mm to prepare a monofilament type steel wire, and when corrugated , except that εx P was set to 0.5 and εx d was set to 0.32h, the rest were carried out in the same manner as in Example 1 to produce corrugated monofilament steel wires for cutting, and the physical properties were evaluated and listed in the following Table 1 together.

Embodiment 3

[0066] Except that εx P was set to 1.0 and εx d was set to 0.26h, the rest was carried out in the same manner as in Example 2 to produce corrugated monofilament steel wires for cutting, and the physical properties were evaluated and listed in Table 1 below.

Abstract

The present invention relates to a wavy-patterned monowire for cutting hard material such as hard glass, semiconductors and superhard alloy. The wavy-patterned monowire for cutting can maintain the performance of an abraser and improve cutting workability and the quality of a cut surface.

Description

technical field [0001] The present invention relates to a corrugated monofilament type steel wire for cutting, and more particularly, the present invention relates to a corrugated monofilament type steel wire for cutting semiconductor ingots, ceramics, glass or similar hard materials. Background technique [0002] Wafers made of silicon (solar cell substrates, etc.), quartz (used in various industrial fields such as automobiles), gallium arsenide (high-frequency electronic products), etc. are ingots that will be made into cylindrical shapes. Formed after cutting into thin disks. The cutting mechanism of the crystal ingot is to use abrasive and wire to cut the object to be cut. At this time, brass-plated monofilament type steel wire was used as the existing wire that functions as an abrasive carrier, but recently, products have been developed in which the surface of the wire is processed to enhance the ability to carry abrasives in order to improve cutting performance.
