< Topic >It possesses the sharpness which is superior, furthermore and it offers the wire saw which is difficult to cause plugging up by the sawdust. SolutionsThe 1st metal wire rod 1 which consists of the cobalt basic alloy and, 2 it consists of the cobalt basic alloy 2nd metal wire rod 2a and 2b and, 3 it consists of the cobalt basic alloy which is wound around 1st metal wire rod 1 3rd metal wire rod it has the substance 6 which possesses with 3a - 3c. 2nd metal wire rod 2a and 2b, crossing mutually helically to opposite direction, in 3rd metal wire rod are respectively wound 3a - 3c. The cutting blade is formed from the convex section 8 which is formed 2 by the intersection of 2nd metal wire rod 2a and 2b. < Selective figure >Figure 3【課題】優れた切れ味を有し、さらに切り粉による目詰まりを生じ難いワイヤーソーを提供する。【解決手段】コバルト基合金からなる第1の金属線材1と、コバルト基合金からなる2本の第2の金属線材2a、2bと、第1の金属線材1に巻き付けられたコバルト基合金からなる3本の第3の金属線材3a~3cとを有する本体6を備える。第2の金属線材2a、2bは、互いに反対方向へ螺旋状に交差して、第3の金属線材3a~3cにそれぞれ巻き付けられる。切断刃は2本の第2の金属線材2a、2bの交点により形成される凸部8から構成される。【選択図】図3
