    摘要: Provided are a method of manufacturing, and a working tool for, a member having a closed-bottom hole portion that can achieve a good yield of the material, can improve the durability of the cutting blade, and can reduce the force required for the work, by forming a hollowed-out bottom portion using a cutting wire having a two-point support. A method of manufacturing a member having a closed-bottom hole portion by inside-removing-working a raw material made of a carbonaceous material, the closed-bottom hole portion having a hollowed-out side portion and a hollowed-out bottom portion formed by hollowing out an inner portion of the raw material, including: a step of forming a cylindrical trench by digging the raw material frontward from a near-side end face of raw material while rotating the raw material, to form the hollowed-out side portion; and a step of forming the hollowed-out bottom portion by supporting a cutting wire inserted into a bottom portion of the cylindrical trench at two points while rotating the raw material, and pressing the cutting wire being supported at the two points in a direction approaching an axis line of the raw material.

    摘要: PROBLEM TO BE SOLVED: To provide a method of producing a member having a bottomed hole, configured to improve yield of a material and durability as a cutting blade by using a two-point supported cutting wire to form a hollowed bottom, while significantly reducing a force required for the work, and to provide a machining tool. SOLUTION: The production method comprising a process of hollowing a material made of a carbon-based material so as to produce a member having a bottomed hole provided with a hollowed side and a hollowed bottom formed by hollowing the inside of the material includes: a step of forming a cylindrical groove by forwardly drilling the material from the front side end surface while the material is rotated in order to form the hollowed side ; and a step of forming a hollowed bottom by supporting, at two points, the cutting wire inserted to the bottom of the cylindrical groove and pressing the two-point supported cutting wire in the direction approaching the axis of the material while the material is rotated.
