An embodiment of a wire saw using a piano wire will be described below. (1) A method in which a piano wire is used as a part of a saw to work on a workpiece to be cut while a normal piano wire is used and a diamond abrasive mixed solution is dropped. (See Fig. 2a) (2) Use thick Cu-plated piano wire and its softness
A tool that holds a diamond abrasive grain of a diamond abrasive grain mixed liquid dropped on a Cu plating layer and acts as a saw when cutting a workpiece. (See FIG. 2b) (3) A diamond wire is attached to the skin portion of the piano wire in advance via a metal to form a saw and improve cutting performance. (See FIG. 2c.) In the figure, 1 indicates a piano wire, 2 indicates a thick Cu-plated piano wire, 3 indicates a soft metal layer, and 4 indicates diamond abrasive grains.

高いものとなる。[0003] Here, when the piano wire of (1), (2), and (3) is evaluated as a saw, the one that immediately uses the piano wire of (1) is the manufacturing cost. Although not high, the cutting performance is low, the diamond abrasive grains are easily detached during cutting of the workpiece, and the diamond abrasive grains scratch the piano wire surface and are liable to break. (2) The one using thick Cu-plated piano wire has good cutting performance, but the diamond plating is well held by the Cu plating layer during cutting, and the piano wire body is dyaded by the Cu plating layer. Approximately 10μ as Cu plating to keep the abrasive grains in order to prevent the inability to form the abrasive grains
Is necessary, and ultimately 20 to 50μ Cu plating is required on the piano wire, and to obtain a plating layer of this thickness, usually 10
The plating is required about once, and the cost is extremely high. (3) In the case where diamond abrasive grains are previously adhered to the skin portion of a piano wire and the diamond abrasive grains are embedded by Ni plating or the like, the cutting performance is good, but the cost is extremely high.

られる。[Manufacturing method] A method for manufacturing a piano wire according to the present invention will be described below with reference to the equipment shown in FIG. The heating furnace 6, the holding furnace 8, the lead bath furnace 9, and the winding unit 10 are arranged in tandem, and gas is supplied to the heating furnace 6 and the holding furnace 8 from the atmosphere gas supply unit 7.
A reel around which the high-carbon steel wire 5 is wound is installed on the inlet side of the heating furnace 6, and the wire 5 is wound by the winding unit 10 after undergoing the processing described below. The high carbon steel wire 5 is heated in a heating furnace 6 at 850 to 950 ° C. for 1 to 10 minutes in an H 2 + H 2 O atmosphere. At this time, the steel hardly oxidizes, and only decarburization proceeds. By selecting the temperature and time, a predetermined decarburization depth from the skin can be obtained. The wire 5 leaving the heating furnace 6 is placed in
Since it is maintained at 750 ° C. for 10 to 20 seconds, the decarburized portion can be easily transformed from austenite to the softest ferrite. Thereafter, the lead wire is quenched at a constant temperature of about 550 ° C. in a lead bath furnace 8 at a constant temperature of about 550 ° C., and the patenting is completed. Is obtained.
