Problems solved by technology

Therefore, if the resin film with abrasive grains is peeled off from the steel wire, the steel wire itself will be exposed, and the abrasion of the steel wire will progress rapidly due to the free abrasive grains supplied when the workpiece is cut, causing the wire to break.
In addition, if the workpiece is cut with a steel wire with the abrasive resin film peeled off, the surface accuracy of the cut workpiece will deteriorate, and the quality of the workpiece will deteriorate.

experiment example 1

[0055] A rolled wire rod (diameter: 5.5mm ). After heat treatment (leading treatment (LP) at 550°C), wire drawing is performed once to a diameter of 0.88mm, and then heat treatment (leading treatment (LP) at 550°C) is performed. Then, the plating layer shown in the following Table 1 was formed, the wire was secondarily drawn to a diameter of 0.132 mm, and then degreased, whereby the base filament was produced.

[0056] As the plating layer, any of Cu—Zn plating layer, Cu plating layer, and Zn plating layer can be formed. The Cu—Zn plating layer has a component composition of Cu: 63% by mass and Zn: 37% by mass, and is formed by electroplating. Cu plating and Zn plating are formed by electroplating. The types of plating layers formed are shown in Table 1 below. In addition, No. 1 and No. 2 in Table 1 are examples without forming a plating layer.

[0057] The drawing speed is 1.70 m / s or 3.30 m / s when the second drawing reaches a diameter of 0.132 mm. The wire drawing spee...

experiment example 2

[0081] As in Experimental Example 1 above, the rolled wire rod was first drawn to a diameter of 0.88mm, and then heat-treated (leading treatment (LP) at 550°C), and then Cu plating was formed, and then secondarily drawn to a diameter of 0.132mm, followed by Degreasing is carried out, thereby producing basal filaments.

[0082] When the second wire drawing was performed to a diameter of 0.132 mm, an oil-based lubricant ("Metelsin (trade name)" manufactured by Kyoeisha Chemical Co., Ltd.) was used. The oil temperature of the lubricant was 25° C., and the wire drawing speed was 3.30 m / sec.

[0083] In Experimental Example 2, degreasing was performed under the following conditions.

[0084] No. 21 shown in the following Table 2 is an example of a base yarn that is not degreased after secondary drawing to a diameter of 0.132 mm.

[0085] No. 22 is an example of a base yarn obtained by degreasing after second drawing to a diameter of 0.132 mm, followed by immersion in acetone for ...

experiment example 3

[0096] As in Experimental Example 1 above, the rolled wire rod was first drawn to a diameter of 0.88mm, then heat-treated (leading treatment (LP) at 550°C) to form a Cu plating layer, and then secondarily drawn to a diameter of 0.132mm, followed by Degreasing, thereby producing basal filaments.

[0097] When the second wire drawing reaches a diameter of 0.132 mm, use an oily lubricant ("Metelsin (trade name)" manufactured by Kyoeisha Chemical Co., Ltd.) or a water-soluble oil lubricant ("Efuko Liyu" manufactured by ADEKA Chemical Suplay Co., Ltd.) 一ベ (trade name)"). The oil temperature of the lubricant was 25° C., and the wire drawing speed was 3.30 m / sec.

[0098] In Experimental Example 3, the conditions at the time of degreasing were changed as follows.

[0099] No. 31 shown in Table 3 below is an example of a base yarn that is not degreased after being secondarily drawn to a diameter of 0.132 mm.

[0100] No. 32 is an example of base yarn obtained by degreasing after sec...

Abstract

Provided is a base wire that is used as a coated saw wire having an organic film on the surface, wherein the base wire is able to minimize the peeling of the organic film. Furthermore, the base wire for the coated saw wire provides the coated saw wire with excellent resistance to the peeling of the organic film. The base wire for the coated saw wire having an organic film on the surface has a steel wire and a galvanized layer formed on the surface of the steel wire.

Description

technical field [0001] The present invention relates to a saw wire used for a sawing machine, and more specifically, to a base wire for a saw wire that is used by blowing abrasive grains onto the saw wire when cutting workpieces such as metals and ceramics. Background technique [0002] Workpieces such as metal and ceramics are cut by a sawing machine equipped with a saw wire. The wire runs in one direction or in both directions (reciprocating direction), and by bringing the wire into contact with the workpiece, the workpiece is cut with an arbitrary width. [0003] The workpiece is cut while spraying a solution containing abrasive grains (hereinafter referred to as free abrasive grains) to the wire. Free abrasive grains contained in the sprayed solution are caught between the workpiece and the wire, and the abrasion of the workpiece is promoted, and the workpiece is cut off. [0004] As a saw wire used for cutting a workpiece while spraying a solution containing free abra...
