- the circumferential grooves 16a to 18b of the rollers 16A to 18B have a predetermined arrangement as shown in FIGS. 4A and 4B when viewed from the wire traveling direction. Therefore, the wire 11 travels in the same plane between the dancer rollers 16A and 16B and the traverse rollers 17A and 17B and between the dancer rollers 16A and 16B and the guide rollers 18A and 18B.
- the wire 11 travels between the traverse rollers 17A and 17B and the guide rollers 18A and 18B within the rotation surface of the dancer rollers 16A and 16B. Accordingly, it is possible to prevent the wire 11 from being twisted in the wire travel path between the bobbins 12A and 12B and the main rollers 13A and 13B.
- the workpiece W is pressed against the wire 11 between the main rollers 13A and 13B while supplying the slurry containing abrasive grains to the workpiece W. Can be cut with high accuracy.
- the wire 11 is a type that holds diamond abrasive grains, it is not necessary to supply slurry.
- the portion of the wire 11 that travels between the traverse rollers 17A and 17B and the guide rollers 18A and 18B is positioned on one plane. For this reason, it can suppress that the wire 11 twists between the bobbins 12A and 12B and the main rollers 13A and 13B. As a result, it is possible to improve the machining accuracy of the workpiece W and prevent the wire 11 from being disconnected. Further, by suppressing the twist of the wire 11, when the wire 11 is a type that holds diamond abrasive grains, it is possible to prevent the diamond abrasive grains from falling off the wire 11.

- the bottoms of the circumferential grooves 18a and 18b of the guide rollers 18A and 18B respectively coincide with each other on the same plane. Accordingly, the positions of the wire portions 11a and 11b and the positions of the rollers 16A, 16B, 17A, 17B, 18A, and 18B are appropriately determined by visual observation and the cameras 19a and 19b, and the rollers 16A to 18B are centered in one direction. Can be easily executed at once.
- the wire portions 11a and 11b are parallel to each other. Therefore, it can be confirmed from one direction whether or not the point 17P on the traverse rollers 17A and 17B and the point 18P on the guide rollers 18A and 18B are aligned with the bottoms of the circumferential grooves 16a and 16b of the dancer rollers 16A and 16B. For example, it is possible to determine whether the centering of the three rollers 16A to 18A or 16B to 18B is accurate. In addition, it is also advantageous in this confirmation that there is no need to change the viewing angle by visual observation or the cameras 19a and 19b, and that there are few viewing points.

Guided by a limited number of rollers. For this reason, the influence of the inertia which acts on a wire with a roller can be reduced, and the unnecessary load which acts on a wire can be reduced. And since there are few positions where the running direction of the wire 11 is changed with a roller, it can suppress that the wire 11 is twisted by a roller. As a result, it is possible to improve the processing accuracy and processing efficiency of the workpiece W, and further prevent wire breakage and diamond abrasive grains from falling off.
- the angles R2a and R2b formed with the surface are not obtuse angles but obtuse or acute angles. For this reason, the torque acting on the wire 11 in the twisting direction is reduced. Thereby, since the twist of the wire 11 is suppressed more effectively, it is possible to further improve the processing accuracy of the workpiece W and further prevent the wire breakage and the diamond abrasive grains from falling off.
- the traverse rollers 17A and 17B are centered on the point 17P where the portion of the wire 11 extending from the dancer rollers 16A and 16B to the traverse rollers 17A and 17B is first applied to the traverse rollers 17A and 17B. It can swing. For this reason, the traverse rollers 17A and 17B can swing according to a change in the amount of the wire 11 wound around the bobbins 12A and 12B. Further, even if the traverse rollers 17A and 17B swing, there is no deviation between the traverse rollers 17A and 17B and the guide rollers 18A and 18B that cause the wire 11 to be twisted.
- the wire saw of the second embodiment is different from that of the first embodiment in that bobbins 12A and 12B and traverse rollers 17A and 17B are arranged so that the wire portion 11a is not parallel to the wire portion 11b.

- the rotating surfaces of the dancer rollers 16A and 16B are horizontal, and the rotating surfaces of the traverse rollers 17A and 17B and the rotating surfaces of the guide rollers 18A and 18B are the dancer rollers 16A and 16B. It is inclined with respect to the rotation plane.
- the point 17P on the traverse rollers 17A and 17B and the point 18P on the guide rollers 18A and 18B are arranged at the bottoms of the circumferential grooves 16a and 16b of the dancer rollers 16A and 16B. By looking at the same height from one direction, it can be determined whether or not the arrangement of the six rollers 16A to 18B is appropriate.
